CHAPTER 1 Description
Introduction
The Medtronic MiniMed 2007D Implantable Insulin Pump System, shown in
Figure 1, brings together sophisticated new technologies to provide continuous
intraperitoneal insulin therapy for patients with Insulin Dependent Diabetes
Mellitus (IDDM). The development of the Medtronic MiniMed 2007D
Implantable Insulin Pump System is the result of years of cooperative research
and development between Medtronic MiniMed and:
• The Johns Hopkins University, Applied Physics Laboratory
• U.S. National Aeronautics and Space Administration, Goddard Space
Flight Center. U.S. National Institutes of Health
Figure 1: Implantable Insulin Pump and
Personal Pump Communicator (PPC)
Description

This manual is intended for use by the physician, surgeon, nurse specialist and all
other members of the healthcare team who care for patients with the Medtronic
MiniMed 2007D Implantable Insulin Pump System.
The Medtronic MiniMed 2007D Implantable Insulin Pump System can be used
with special U-400 insulin formulations specifically labeled for use with the
Medtronic MiniMed Implantable Insulin Pump System.
The system consists of three major components:
• Implantable Insulin Pump
• Side Port Catheter
• Personal Pump Communicator (PPC)
Each of these components, as well as system safety features, are discussed in
detail in the following sections.
Description 3
Implantable Insulin Pump
The Implantable Insulin Pump (Pump) is a round disc, 8.1 cm (3.2 inches) in
diameter, 2.0 cm (0.8 inches) thick. The Pump weighs 131 grams (4.6 ounces)
when empty. The outside case of the Pump is made of titanium. Titanium is a
biocompatible metal used in many types of implantable medical devices. A
tangential Side Port Catheter is attached to the Pump prior to implant, using a
locking connector (see Figure 2).
Figure 2: The Implantable Insulin Pump
The Implantable Insulin Pump is an advanced insulin infusion device with
sophisticated microelectronics. It delivers a special insulin medication, using a
pulsatile solenoid pumping mechanism that is hermetically sealed inside the
biocompatible titanium case. Insulin delivery rates and profiles are programmed
using an external device, the Personal Pump Communicator (PPC). Specific
information on the Implantable Insulin Pump features is outlined in the following
sections.
Description
4
The Pump has six major components. These components are outlined below:
• medication reservoir
• pumping mechanism
• microelectronics
• antenna
• battery
• tone transducer
Other components of the Pump include the inlet valve, fill port, septum,
cyclopentane gas and 20µm filter. Figure 3 shows the interior components of the
Pump.
Figure 3: Interior of the Implantable Insulin Pump
The Medication Reservoir stores approximately 15 ml or 6,000 units of a
special U-400 insulin. Depending on an individual’s insulin requirements, the
medication reservoir is refilled once in approximately every two to three months.
The medication reservoir is maintained at a negative pressure (vacuum) at all
times to allow for safe and reliable filling. This vacuum prevents any risk of
insulin leakage in the event of a breach in the Pump case or reservoir. The
reservoir is refilled with a special needle (Medtronic MiniMed Refill Needle
MMT-4102). The fill port has a 20 micron filter to prevent particulate material
from entering the Pump and a redundant septum and valve configuration to
prevent entry of body fluids.
Description 5
The Pumping Mechanism is a solenoid-operated, hermetically-welded pulsatile
system. The pumping mechanism is designed to seal automatically to prevent
leakage both into and out of the reservoir under physiologic temperatures and
pressures. The mechanism is designed to provide an insulin delivery accuracy of
within 10% from its labeled stroke volume. Individual Pumps are calibrated to
one of seventeen different stroke volumes, ranging from 0.42 µL to 0.58 µL per
stroke, in increments of 0.01 µL.
The Microelectronics act as the brain of the Pump. The microelectronics contain
two microprocessors which monitor and control all pump-stroke activity. All
commands delivered from the PPC via RF telemetry to the Pump are then
acknowledged back to the PPC. The Pump has a large memory which stores
Pump specifications and programming history.
The Antenna receives radiowaves from the PPC and delivers PPC programming
commands to the Pump microelectronics.
The Battery is a custom-made lithium carbon mono-fluoride power cell, which
supplies energy to the pumping mechanism and microelectronics. It is similar to
batteries used in pacemakers and is designed to provide 6 to 10 years of service,
depending on the infusion rate (refer to pump specifications).
The Tone Transducer emits beeps to indicate certain alarm conditions. These
beeps are designed to be audible through the skin and can be set with the PPC to
one of two volumes. The Pump can also be programmed to emit beeps that signal
a programmed change in the medication delivery rate.
Radio-Opaque Identification is featured in the Implantable Insulin Pump. In
the event of an emergency, the name of the manufacturer and the Pump model
number can be identified with an x-ray.
Insulin medication
Only specially formulated U-400 insulins that are specifically labeled for use
with the Medtronic MiniMed Implantable Insulin Pump System can be used in
the model 2007D Pump.
These special U-400 insulins are supplied in 10mL vials.
Description

Side Port Catheter
The Side Port Catheter (Catheter) transports insulin from the Pump into an
individual’s peritoneum where it is absorbed. The Catheter is made of
polyethylene-lined silicone rubber, which is biocompatible with subcutaneous
and intraperitoneal tissues and supports the stability of the special insulin. The
Catheter is designed with two perpendicular sections: a proximal subcutaneous
section which attaches tangentially to the Pump with a locking connector, and a
distal section which is placed in the peritoneum (see Figure 4). To enable post-
implant localization, a radioopaque stripe runs the length of the Catheter.
The Catheter Side Port is intended to provide access to the Catheter and Pump
outlet, in order to perform the non-surgical interventions and diagnostic
procedures described in Appendices E, F and G. The side port allows for the
introduction of a needle and small syringe to clear Catheter obstructions using
pressures up to 100 psi. It also allows for the introduction of a needle to verify
Pump stroke volume.
Figure 4: The Intraperitoneal Catheter and Side Port
Description 7
Personal Pump Communicator (PPC)
The Personal Pump Communicator (PPC) is the hand-held component of the
Medtronic MiniMed 2007D Implantable Pump System (see Figure 5).
The PPC allows the physician and patient to communicate with the Pump by
transmitting radio frequency messages when the PPC is held within 3” of the
Pump. Additionally, the PPC stores important programming information in its
memory.
Figure 5: Personal Pump Communicator (PPC)
The PPC has been designed so the physician and patient can:
• Program basal infusion rates (up to 48 basal rates per day, 3 different
patterns)
• Deliver or suspend an immediate, Square Wave, or Dual Wave Bolus of
insulin
• Deliver or cancel a temporary basal rate
• Review the insulin delivery history
• Enter personal events (meal, snack, exercise)
Independent of the programming function, the PPC is able to receive and record
certain programming data from the Pump. The recorded information is accessible
and can be displayed on the screen.

CHAPTER 2 Indications and
contraindications
Indications for use
The Medtronic MiniMed 2007D Implantable Insulin Pump System is indicated
for intraperitoneal administration of exogenous insulin in patients with diabetes
mellitus.
The model 2007D Pump can only be used with special U-400 Insulin
formulations specifically labeled for use with the Medtronic MiniMed
Implantable Insulin Pump Infusion System.
Contraindications for use
The Medtronic MiniMed 2007D Implantable Insulin Pump System is
contraindicated in patients who:
• are unwilling or unable to monitor their blood glucose level at least four
times per day.
• are unwilling or unable to make programming modifications to the Pump
based on glucose level readings.
• are unable or unwilling to administer insulin by other means, if necessary.
• are unable or unwilling to comply with the guidance and advice of their
treating physician and other healthcare providers.
• reside at or travel (other than by pressurized commercial aircraft) at
elevations above 8,000 feet.
• have other medical or mental conditions which may place the patient at risk.
• are unwilling or unable to return for routine insulin refills according to their
dosage requirements (approximately once every 90 days).
• present or have a history of sensitivity to titanium alloy, polysulfone or
silicone materials used in the implanted components of the system.
Indications and contraindications
10
Possible adverse effects
The model 2007D is essentially identical to the model 2007C Pump except for
the change in gas needed to maintain negative pressure in the reservoir.
Evaluation of components used in the Medtronic MiniMed 2007C system has
spanned a period of approximately 4 years and involved approximately 380
patients from both the U.S. and Europe. Although clinically relevant over-
delivery of insulin did not occur during the 4 year evaluation period, there is a
potential for such an occurrence.
The following are specific adverse effects which should be understood by the
physician and explained to the patient. These do not include all adverse effects
which can occur with surgery in general or with the use of this device, but are
important considerations, particularly in the treatment of diabetic patients. The
general surgical risks, as well as operative site cosmetic risks, should be
explained to the patient prior to surgery.
• Abdominal Pain • Foreign Body Reaction
• Inflammation at Refill Site • Skin Erosion
• Infection • Pocket Lymph Edema
• Necrosis • Hyperglycemia
• Hypoglycemia • Ketoacidosis

CHAPTER 3 Personal Pump
Communicator (PPC)
Introduction
The Personal Pump Communicator (PPC) has a comprehensive set of program-
ming features to control the Implantable Insulin Pump. The PPC cannot be used
by the patient until it has been initialized by the healthcare professional. This
chapter of the manual is divided in two parts:
The first part (Part 1) will describe the PPC/PUMP system initialization process
that will be performed the day prior to implant.
The second part (Part 2) will describe how to use the additional features that the
healthcare professional or patients can activate.
PPC icons
After initialization, the PPC Main Screen displays the time (12hr. or 24hr. for-
mat), month, day and a variety of icons. The type and purpose of these icons are
as follows:
Bell Icon:
Displayed when the PPC receives a telemetry message from the Pump indicating
that the Pump has detected an alarm condition, when a PPC error is detected and
when the Pump is Suspended or Stopped.
Reservoir Level Indicator Icon:
The reservoir icon is composed of 4 segments that indicate how full the Pump
reservoir is, based on the history of Pump delivery.
Insulin Delivery Icon:
The PPC simulates spinning the delivery icon when insulin delivery is in progress
by displaying alternating patterns, the pattern changes every 4 seconds. When the
Pump is delivering a bolus, the pattern will show three delivery segments. When
the Pump is delivering a basal rate, the pattern will show one delivery segment.
When the Pump is not delivering, all four segments will be displayed.
Personal Pump Communicator (PPC)

Certain features of the PPC such as programming and dosing limits can be set
only by the healthcare professional in a password-protected mode called the
Supervisor Mode. Information pertaining to initializing the PPC and entering the
PPC Supervisor Mode is not included in the Patient User Manual.
PPC buttons
Communicating with the Pump
Place the PPC near the Pump when the screen displays,
“PPC COMMUNICATING.” The word "COMMUNICATING" will blink as
indication of successful communication. If a communication link between the
PPC and Pump is not established, a “TELEMETRY COMM ERROR 3” message
will appear. The PPC will beep six times once every minute until the screen is
acknowledged by pressing SEL and ACT. The screen will then display “PPC
COMMUNICATING” again.
After a communication is established between the PPC and Pump and program
information is successfully transferred to the Pump, the PPC will beep once and
return to the Time/Date screen.

Part 1: PPC/Pump system initialization
The Implantable Insulin Pump arrives from Medtronic MiniMed with preset fac-
tory default values. During the initialization process these preset values are
downloaded into the PPC memory. The preset values can then be changed by the
healthcare professional, allowing the system to be personalized for each patient.
The factory default values are as follows:
Initialize the PPC
When the healthcare professional receives a new PPC it must be “married” to the
Pump. Following are the basic steps used to initialize a Pump System the day
prior to implant:
1. The PPC is delivered without a battery in place.
After installing a new battery, the PPC will beep
six times and the screen will identify the PPC

CHAPTER 4 Pump implantation
Preprogramming and pre-testing the Pump
Every Implantable Insulin Pump is fully tested before shipment and is accompa-
nied by a package insert indicating the measured stroke volume and Pump type.
Prior to shipping, each Pump is filled with sterile rinse buffer to assure sterility.
Programming of the Pump may be performed a day before Pump implantation.
The Implantable Insulin Pump may be programmed through the outer tray of the
sterile package. First, the PPC needs to be “married” to the Pump, then the Pump
function is verified by performing the initialization procedure described in Chap-
ter 3, PPC/Pump System Initialization.
Registration card
To ensure proper patient identification and device serial number tracking, the
Registration Card that accompanies each Pump must be completed and promptly
returned to Medtronic MiniMed.
Supplies and solutions
Before preparing the Pump, be sure to read Appendix D, Precautions and Gen-
eral Procedures. Assemble the necessary materials prior to starting the proce-
dure:

• Sterile markers and Steri-Strips®
• Three (3) refill Kits - MMT-4105:
• 1 kit to remove shipping fluid from Pump
• 1 kit to fill the Pump with U-400 INSULIN (to rinse the pump)
• 1 kit to fill the Pump with U-400 INSULIN (final insulin fill)
• One (1) 3 mL syringe (fluid barrier)
• Three (3) Medtronic MiniMed refill needles, MMT-4102
• Three (3) 18 gauge needles
• One (1) Implant Worksheet
• One (1) Back-up Pump System: PPC, Pump, Port Catheter
Solutions
• One (1) bottle of sterile water, room temperature
• One (1) vial 10 mL Rinse Buffer (RB), MMT-2008
• Four (4) vials 10 mL U-400 INSULIN, stored at room temperature for a
minimum of ten hours prior to surgery.
Emptying and filling the Pump
To prepare the Pump for implantation, the Pump must be emptied and then filled
twice and tested with insulin. These procedures are performed in the operating
room prior to surgery. As this is a surgery, all supplies and required equipment
should be prepared in accordance with the institution’s approved sterile proce-
dures.
When you remove the Pump from the sterile box,
do not remove the plastic tubing placed at the Pump
outlet. Trim the distal part with a scalpel blade. This
tubing will be used for the “Stroke Volume Mea-
surement” procedure.
A sterile field is established in the operating room to prepare the RINSE
BUFFER (RB) syringe and remove the shipping fluid from the Pump. Document
the Pump, Catheter and PPC serial numbers on the Implant Worksheet.
!
WARNING
Pump implantation 55
Remove shipping fluid from the Pump
1. Using aseptic technique, open the Pump sterile package. Do not remove the
plastic tubing from the Pump outlet. Trim the distal part of the tubing with
the scalpel blade.
2. Remove the refill syringe from the refill kit package.
3. Firmly attach the two-way stopcock to the refill syringe and attach an 18
gauge needle to the stopcock.
4. Draw approximately 4 mL of RINSE BUFFER into the refill syringe.
5. Fill the hub of the refill needle with RINSE
BUFFER and firmly attach it to the
stopcock, prime the needle and close the
stopcock. (See Figure 6.)
6. Retract the plunger until it locks into place.
This should be no further than 55 mL. Do
not go beyond the vent hole. Press the lock
into the plunger groove to be sure it is firmly
secured.
7. Fill one 3 mL syringe with RINSE BUFFER
(RB) and attach a needle.
8. Fill the Pump fill port using the 3 mL
syringe. Any time a refill needle is to be
inserted into the Pump fill port, a fluid
barrier must be present to prevent air from
entering the Pump reservoir.
9. With the stopcock still closed, insert the RB
syringe into the Pump fill port.
10. Open the stopcock and allow the syringe
vacuum to empty the Pump of shipping
fluid. Allow 30 seconds after the fluid level
appears to have stopped rising in the refill
syringe, to assure the Pump is completely
emptied. Close the stopcock and remove the
syringe.

Rinse the Pump with insulin (IN1)
1. Remove the second refill syringe from the refill kit package.
2. Firmly attach the two-way stopcock to the refill syringe and attach an 18
gauge needle to the stopcock. Use the sterile marker to label the syringe,
“IN1”.
3. Draw 20 mL of INSULIN (two vials) into the refill syringe.
4. Remove the 18 gauge needle and expel all air bubbles in the syringe.
5. Close the stopcock.
6. Retract the plunger until it locks into place. This should be no further than 55
mL. Do not go beyond the vent hole. Press the lock into the plunger groove to
be sure it is firmly secured.
7. Shake vigorously for a minimum of 30 seconds to degas the INSULIN.
8. Point the syringe tip upward and slowly open the stopcock to vent the

2. With the stopcock closed, insert the refill needle into the Pump fill port.
3. Open the stopcock. Maintain downward pressure on the barrel of the syringe
to ensure the inlet valve of the Pump remains open.
Never push on the refill syringe plunger to fill the
Pump. When the refill needle is properly seated in
the fill port of the Pump, the vacuum in the reser-
voir will draw the insulin from the syringe.
4. Allow the Pump vacuum to draw the INSULIN into the reservoir. When the
INSULIN stops moving, the Pump is filled. Close the stopcock and remove
the syringe.
5. Prepare the IN1 syringe for aspiration. Remove any air from the syringe,
prime the needle, close the stopcock and obtain a vacuum by pulling back on
the plunger until it locks. Press the lock into the plunger groove to be sure it
is firmly secured. A fluid barrier of at least 2 mL should remain in the

Measure stroke volume
1. Place the PPC in the sterile bag. Enter the Supervisor Mode. The screen
displays “PUMP REFILL”. Press ACT until the “SET REFILL AMOUNT”
screen appears. When filling the Pump for the first time, set the
“EXTRACTED AMOUNT” to zero. Otherwise, enter the amount of insulin
extracted. Then use the and buttons to enter the refill amount from the
Implant Worksheet. Program the Pump.
2. Again, enter the Supervisor Mode and program “STOP PUMP”. From the
screen “PUMP STOPPED”, press SEL. “PUMP STOPPED” will begin
flashing. Press both the and buttons at the same time, until the screen
changes to the password screen. Reenter the password and the screen will
change to “PUMP REFILL.” Press SEL to reach the “PRIMING” screen.
“NO” will be flashing. Use the and buttons to select “YES,” then press
ACT. When the word “CONFIRM” is highlighted, press ACT again. Place
the PPC near the Pump to complete the communication process. Record the
time the priming bolus was initiated on the implant worksheet.
3. Listen for five beeps and observe that fluid is being pumped from tubing
attached to the Pump outlet.
4. Attach the 18 gauge needle (from the 3 ml syringe filled with RINSE
BUFFER) to the plastic tubing from the Pump outlet.
5. Remove the 3 ml syringe and fill the needle hub.

Figure 8: Testing Pump stroke volume with a pipette
6. Insert the pipette into the hub. A meniscus of fluid will be present in the
pipette. This should be done on a flat surface with the pipette/tubing
assembly horizontal (see Figure 8).
7. Note the exact location of the fluid meniscus in the pipette.
8. Measure the stroke volume by noting the volume displaced by a minimum of
10 pulses. Record the total volume delivered and the number of pulses on the
Implant Worksheet. Divide the total volume delivered by the total number of
pulses used to deliver that volume. The volume per stroke must be between
0.40 and 0.60 µL. Record this value on the Implant Worksheet.
Prepare the Side Port Catheter
The Side Port Catheter (“Catheter”) is attached to the Pump before implantation;
however, it must be primed with INSULIN and inspected before being attached
to the Pump.
Never insert a needle into the connector end of the
Catheter for priming or for testing. There is a preci-
sion sealing surface in the connector that may be
damaged by the insertion of any needle.
1. Keep the Catheter in its package until the Pump is prepared and stroke
volume has been verified. Remove the Catheter from its sterile package and
document the serial number on the Implant Worksheet.
2. Using the last insulin syringe (IN2) from the Pump preparation procedure,
enter the Catheter port cone and push a small volume of insulin out of the
connector end of the Catheter. This primes the proximal portion of the
Catheter and cleans any debris from the connector outlet. Remove the
syringe.

4. Inspect the outlet of the Pump for debris. Debris, especially fibers, left in the
fluid path will compromise the function of the Catheter check valve. Rinse
the outlet tube of the Pump with water from a syringe, if necessary. Avoid
wiping the Pump with gauze or drapes that will leave fibrous debris.
5. Pull the locking bar out and gently push the Catheter straight down onto the
Pump outlet. Never twist the connector.
6. Only after the Catheter is seated, squeeze the connector (see Figure 10, item
1), firmly against the Pump between the thumb and forefinger of one hand.
Then push the locking bar (item 2) into place with the thumb of the other
hand.
Figure 10: Proper attachment of the Side Port Catheter to Pump
7. Verify the Catheter is securely attached to the Pump. Look into the connector
and observe the position of the locking bar with respect to the Pump
connector outlet. Check the side port connector hub for abnormalities (e.g.,
cracks, misalignment.)
8. Using the IN2 refill syringe, enter the Catheter side port cone and push a
small amount of INSULIN out the Catheter tip. Verify that no insulin flow is
observed at the Pump/Catheter interface. Remove and reseat the Catheter if
flow is noted. Remove the syringe.
9. Confirm insulin delivery from the tip of the Catheter and note it on the
Implant Worksheet. The INSULIN will form a dome on the tip of the
Catheter. Pulsatile delivery will not be obvious. If the priming bolus has
already ended, program an immediate bolus (about 20 units) to confirm
delivery. (This bolus may be canceled after delivery is verified.)
Pump implantation 63
10. At the end of the bolus, rinse the outside of the Pump thoroughly with sterile
water to remove traces of INSULIN. The Catheter tip should not be placed in
the water. Protect the Pump with sterile drapes until the surgeon is ready to
implant it. Verify that the priming bolus is finished or canceled prior to the
implantation.
The Pump and Catheter are now ready for implantation.

64
Performing the surgical procedure
Pre-operative evaluation
The Pump implant depth should not exceed 5 cm (2 inches) beneath the surface
of the skin. If the Pump is implanted too deeply in the subcutaneous tissue it may
be difficult to access the refill port.
Formation of the pump pocket
Pump implantation can be performed either under local or general anesthesia.
After satisfactory anesthesia, a pre-selected abdominal site is prepped and draped
in the customary surgical method.
A transverse or longitudinal incision is made and deepened through the skin and
subcutaneous tissue. Care should be taken in choosing the location of the incision
so the suture line is next to but not over the Pump inlet fill port or the Catheter
side port. A subcutaneous blunt dissection is performed to create a pocket large
enough to accommodate the Pump. Meticulous hemostasis should be established
with electrocautery.
The Pump is secured to the fascia of the abdominal musculature using the three
suture tabs provided. Securing the Pump with all three suture tabs is recom-
mended, as it will prevent migration, rotation or inversion in the pocket and pos-
sible dislodgment of the Catheter.
Figure 11 indicates a possible Pump placement and corresponding incision sites.
Pump implantation 65
Figure 11: Example of Pump placement
Pump implantation
66
Catheter placement
The Catheter is not designed to be tunneled subcutaneously. The Catheter inser-
tion should be at the extreme edges of the Pump pocket.
At a site not directly beneath the Pump, the layers of abdominal musculature are
divided to expose the peritoneum. Concentric purse string sutures are placed and
the peritoneum is exposed with a 1 cm incision. The distal tip of the Catheter is
placed in the peritoneal space. The flange of the Catheter is sutured firmly to the
fascia of the abdominal musculature. Sutures should only be placed on the rein-
forced flange of the Catheter. Sutures must not be placed directly on the Catheter
itself.
Never trim or cut the tip of the Catheter.
The implant site should be irrigated with an antibiotic solution. Interrupted
absorbable sutures should be used to approximate the subcutaneous tissues and
the skin closed with a running subcuticular absorbable suture. The wound is
dressed using standard surgical technique. At the end of the surgery, place an
abdominal binder over the implant site. This binder must be worn until the cap-
sule has formed (about 1 month.) The binder is recommended because it will
obtain a better cosmetic result and minimize the post operative swelling.

Post-operative management
Post-operative hospitalization
After implantation, the surgical incision should be inspected for any signs of
unusual swelling, tenderness, pain, or drainage. Potential post-operative compli-
cations include Pump pocket seroma, wound dehiscence, wound infection, and
catheter dislodgment.
Length of post-operative hospitalization depends upon how rapidly the patient
adjusts to the Pump and how quickly blood glucose levels
stabilize. During post-operative hospitalization, the Pump can be reprogrammed
to accommodate the needs of the patient. As post-operative stress decreases,
insulin requirements may decline. It may be necessary to make several changes
in insulin delivery rates during the first few days following implantation.
Patients must be thoroughly educated in all aspects of follow-up care with the
Pump. The Medtronic MiniMed Patient Manual should be used to supplement
patient education. Prior to discharge, patients should:
• Fully understand how to use their PPC;
• Know what to do in the event of Pump or PPC difficulties;
• Have scheduled their first refill appointment;
• Have set an appointment for their first follow-up visit;
Post-operative x-rays
The Catheter has been designed with a radio-opaque stripe for identification after
implantation. A lateral and anterior X-ray is recommended after implantation to
locate and document the position of the Catheter. This radiograph should be kept
with the patient’s records for future reference.

CHAPTER 5 Pump refill procedure
Introduction
Initial appointments for Pump Refills should be made with patients at the time of
implantation. Subsequent appointments should be made in advance, normally
during each refill procedure. The Pump stores approximately 6,000 units of insu-
lin medication and typically requires a refill every two to three months. In order
to maintain the physical stability of the insulin, the Pump must be refilled at a
maximum interval of no more than 90 days. The PPC will display warning mes-
sages to alert the patient of calculated low or emptied reservoir volumes.
The low reservoir message will appear when the PPC calculates that 800 (2 ml)
or fewer units of insulin medication remain in the Pump. The empty reservoir
message will appear when the PPC calculates that 400 or fewer units (1 ml) of
insulin remain. The time to medication depletion depends upon the insulin deliv-
ery rate of the Pump.
The Pump refill procedure should always be sched-
uled in advance of PPC “low reservoir” or “empty
reservoir” messages.

Supplies and solutions
The refill kit (MMT-4105) is intended exclusively for use with the
Medtronic MiniMed 2007D Implantable Insulin Pump System. The refill kit con-
sists of a specially designed syringe and stopcock for removing fluids from and
placing fluids into the Pump. Use only refill needles (MMT-4102) available from
Medtronic MiniMed to perform all Pump refill procedures. This 22 gauge needle,
featuring a rounded, lubricated tip and a beveled side hole, has been specially
developed to mate with the Pump fill port.
Use of other needles may result in damage to the
Pump septum in the fill port, and may allow body
fluids to enter the Pump.
Below is a list of the supplies and solutions necessary to perform the refill proce-
dure:
Supplies:
• Steri-Strips® and Markers
• The Patient’s PPC, Glucose Monitoring Equipment, Drapes
• One (1) Scale (0.01 gram resolution)
• One (1) 250 ml Sterile Beaker
• One (1) Port Locating Template - MMT-4106
• Two (2) Refill Kits - MMT-4105 - Three (3) Medtronic MiniMed MMT-
4102 Refill Needles (Extra needles should be available for use.)

WARNING
Pump refill procedure 71
Prepare for pump refill
NOTE: Before beginning any refill, rinse, flush, or pressure
measurement procedure, carefully read Appendix D,
Precautions and General Procedures.
Never push on the refill syringe plunger to fill the
Pump. When the refill needle is properly seated in
the Pump fill port, the vacuum in the Pump reser-
voir will draw the insulin from the syringe into
the reservoir.
To prepare for emptying and refilling the Pump, perform the following steps:
• Use the “HISTORY” feature of the PPC to determine the amount of insulin
medication remaining in the Pump. Make sure that ACT is pressed on the
“READ PUMP DATA” screen to update PPC history from the Pump.
Record this value on the refill worksheet (Appendix C).
• Prepare a sterile field. The physician should scrub, mask and glove for the
refill procedure. Refilling the Pump is an aseptic procedure.
• (See Appendix D, Precautions and General Procedures.)
• Aseptic skin preparation of the patient’s Pump refill site should be
performed using your institution’s standard operating procedures.

CHAPTER 6 Explanting the Pump
System
Explant considerations
When the battery in the Pump is depleted or if acceptable glycemic control can-
not be achieved, it may become necessary to explant the Pump system.
Prior to explantation, it may be possible to perform interventions that could cor-
rect certain conditions. These procedures are described in Appendices E and F.
If all appropriate interventions have been exhausted without an acceptable out-
come, please contact Medtronic MiniMed prior to scheduling a Pump explanta-
tion.
Returning devices/components to Medtronic
MiniMed
Explanted Pumps and Catheters or other components should be returned to
Medtronic MiniMed for evaluation. Please call Medtronic MiniMed and obtain a
Returned Sales Order (RSO) number prior to each return.
Explanted devices must be sealed in an appropriate biohazard container and
packed with a gauze pad soaked with sterile saline. The shipping container
should be water tight. Chemical and reliability analysis require that the device
not dry out during transportation.
Be certain to include required patient information as well as the RSO number,
date, and reason for the explant and place all pertinent documentation in a water
tight document package. Put the RSO number on the shipping label.

CHAPTER 7 Warnings and precautions
Warnings
The Physician should be completely familiar with the function of the Pump,
Catheter, and PPC prior to use. Patients should be provided a complete copy of
the Patient Manual and have demonstrated the ability to program the PPC,
recognize and respond to safety alarms, and take care of the device prior to
discharge.
Only special U-400 insulins specifically labeled for use with the Medtronic
MiniMed Insulin Infusion Systems may be used in the Medtronic MiniMed
2007D Implantable Insulin Pump. Use of other insulin types may cause damage
to the Pump mechanism resulting in impaired insulin delivery or Pump failure.
Any unauthorized changes or modifications made to any component of the
Medtronic MiniMed 2007D Implantable Insulin Pump System may prevent
effective use of that and other components.
Electrotherapy
The Medtronic MiniMed 2007D Implantable Insulin Pump System has been
tested in close proximity with electrosurgical, electrocoagulation, and cardiac
defibrillation medical equipment. Typical use of this type of device has not
affected the Pump. However, patients should be instructed to test Pump function
(e.g., self test) after such procedures to determine that the Pump and PPC are
operating properly. If the system is not performing correctly, contact Medtronic
MiniMed.
Warnings and precautions
82
Diagnostic ultrasound
The Medtronic MiniMed 2007D Implantable Insulin Pump System has been
tested during diagnostic ultrasound procedures. These procedures have no effect
on Pump performance. However, patients should be instructed to test the Pump
function (e.g., self test) after such procedures to determine that the Pump and
PPC are operating properly. If the system is not performing correctly, contact
Medtronic MiniMed.
Ultrasound therapy
The Medtronic MiniMed 2007D Implantable Insulin Pump System should not be
exposed to therapeutic ultrasound procedures such as lithotripsy. Exposure to
ultrasound therapy may damage the Pump, and not be immediately apparent.
Diagnostic radiation
The Medtronic MiniMed 2007D Implantable Insulin Pump System has been
tested during diagnostic radiation procedures, such as Computed Tomography
and X-ray. These procedures have no effect on Pump performance. However,
patients should be instructed to test the Pump function (e.g., self test) after such
procedures to determine that the Pump and PPC are operating properly. If the
system is not performing correctly, contact Medtronic MiniMed.
Elevated anti-insulin antibodies
The results of clinical investigations suggest a small population of patients may
develop anti-insulin antibodies when using the Medtronic MiniMed 2007D
Implantable Pump System and U-400 insulin. Patients with multiple autoimmune
disorders may be more susceptible to developing high titers of anti-insulin
antibodies, which in turn may cause symptoms. There was no correlation
between length of exposure to the study drug and the resultant titer of anti-insulin
antibodies. Elevated levels of anti-insulin antibodies alone have been proven not
to interfere with diabetes management using continuous intraperitoneal insulin
infusion with this system.
Warnings and precautions 83
Environmental conditions
The Medtronic MiniMed 2007D Implantable Insulin Pump System should not be
exposed to extreme electrical or magnetic fields. Although it is not possible to
include every environmental condition that may affect the Pump, most are listed
below. Please contact Medtronic MiniMed when in doubt if certain
environmental exposure will affect the pump.
DO NOT EXPOSE THE MEDTRONIC MINIMED
2007D IMPLANTABLE INSULIN PUMP SYSTEM
TO ANY OF THE FOLLOWING CONDITIONS:
• Magnetic Resonance Imaging (MRI) Procedures.
• Lithotripsy Treatment.
• Large Rotating Magnetic Fields - Refers to large industrial rotating
magnetic fields, such as those found in Industrial Power Plants.
• Magnets Held Directly Over the Pump.
• High Power Radio or Satellite Transmitting Towers.
• Altitudes Above 2,400 meters (8,000 feet).
• Therapeutic Ultrasound
• Therapeutic Radiation
The Medtronic MiniMed 2007D Implantable Insulin Pump System is not
designed for use at elevations above 2,400 meters (8,000 feet). Use of the Pump
System at higher elevations may result in insulin over delivery, which may cause
personal injury or death. Therefore, patients who live at elevations above 2,400
meters (8,000 feet) should not use the Pump. Patients who use the Pump and who
plan to travel to an elevation above 2,400 meters (8,000 feet) should first have
their Pump reservoir emptied of insulin, and they must self-administer insulin by
other means for the duration of the trip and until their Pump reservoir is refilled
again.
(This warning does not apply to travel on commercial aircraft because normal
cabin pressurization is adequate to ensure proper operation of the Pump.)
• Diving Below 7.6 Meters (25 Feet).
• Physical Damage to the Pump or Pump Pocket.
!
WARNING
Warnings and precautions
84
Physicians should instruct patients to avoid any sharp blows or pressure directly
at the Pump location. A direct hit by an object such as a baseball may damage the
Pump and/or injure the Pump pocket. Extreme pressure on the Pump may cause
the sutures and the tissue pocket to be damaged. As a result, the Pump may move
from its pocket and possibly dislodge from the Catheter.
If the Pump has been damaged by such a blow, the patient should be instructed to
contact their physician. Physicians may order a pressure bandage or a reduction
in the patient’s physical activity until the pump pocket reheals completely.
• Exposure to Extreme Body Temperatures
Exposure to elevated body temperatures in excess of 104°F (40°C) will
compromise the negative pressure reservoir safety feature of the Medtronic
MiniMed 2007D Implantable Pump. Glucose levels should be monitored closely
if this occurs.
Sterilization
The Pump, Catheter and the refill kit are sterilized with ethylene oxide (EtO).
The Pump System is NOT Reusable.
If the sterile package has been opened, damaged or tampered with DO NOT USE
the packaged device.
NOTE: Do Not Re-Sterilize the Implantable Insulin Pump
NOTE: Do Not Re-Sterilize the Side Port Catheter
NOTE: Do Not Re-Sterilize Components of the Refill Kit.
The Pipette (MMT-4104), may be resterilized using autoclave, EtO or according
to hospital procedures.
The Template (MMT-4106) may be resterilized using steam autoclave or EtO per
hospital procedure. This template is made from polycarbonate plastic and will
have a limited life in steam autoclave cycle. The template will not withstand dry
heat autoclave cycles.
Warnings and precautions 85
Precautions
Emergencies and the use of conventional insulin supplies
Physicians should advise patients who are implanted with the Medtronic
MiniMed 2007D Implantable Insulin Pump System how to deal with emergency
conditions such as hyperglycemia and hypoglycemia. Patients should always
carry conventional insulin supplies with them, including insulin and a means to
inject it, in the event of impaired insulin delivery by the Pump System. Delivery
of insulin can become impaired due to a failure of a Pump and/or PPC, or a
Catheter occlusion. Replacement of the Pump, PPC or Catheter may be required.
Physicians should review the Pump replacement and Catheter clearing
procedures in this Physicians Manual
PPC reliability requirements
The PPC is a sensitive electronic device, and can incur physical damage. If the
PPC is dropped or receives an impact patients should be instructed to
immediately perform a SELF TEST to check the displays for proper operation. If
the PPC does not display correctly, a replacement PPC is required. Patients
should initiate alternative diabetes management until a replacement PPC is
received.
The PPC housing is not watertight and it may malfunction if immersed in water.
“Condensing humidity” conditions such as steam rooms should also be avoided,
because condensation can also damage the PPC’s microelectronics. If either
situation occurs, contact Medtronic MiniMed immediately and arrange for the
repair or replacement of the PPC. If the PPC is accidentally splashed, sprayed or
immersed, remove excess moisture with a soft towel and then place the PPC in a
warm place to thoroughly dry. When dry, perform a “SELF TEST.” If the PPC
does not display correctly, call Medtronic MiniMed to replace the device.
Maximum dosages
The physician can program specific limitations to insulin Basal Rates and Bolus
amounts, as well as total daily insulin usage. These limitations provide some
control of patients’ ability to program their insulin regimens, and to avoid
overdosing.
Warnings and precautions
86
Electrical and magnetic fields
Common electrical and magnetic fields that do not affect the Pump include
microwave ovens, satellite receiving dishes, common household appliances,
security devices found in department stores and airports, standard medical X-
rays, cellular phone, and radiowaves.
87
CHAPTER 8 Adverse reactions
Adverse reactions
In clinical studies, adverse reactions associated with the Medtronic MiniMed
2007D Implantable Pump included hypoglycemia, diabetic ketoacidosis,
hyperglycemia, skin erosion, infection, abnormal healing, elevated anti-insulin
antibodies, intestinal obstruction, post-operative discomfort and pain. Pump
System malfunctions in order of frequency and seriousness include, insulin
aggregation resulting in insulin under-delivery, Catheter occlusion or tissue
overgrowth, premature depletion of the Pump battery, and failure of Pump
electronics. Adverse events associated with the use of U-400 insulin are
described in the package insert accompanying the insulin medication.
Prevention
The majority of adverse reactions in patients using the Medtronic MiniMed
2007D Implantable Pump System can be prevented by teaching patients
dependable blood glucose monitoring. The patient plays a significant role in
diagnosing and correcting Pump System performance problems. Should Pump
performance change, the patient would be able to detect a change in blood
glucose levels.
Patients should be instructed to contact their physi-
cian’s office, if they experience unresolvable difficul-
ties with the Pump System. Patient visits and
diagnostic procedures may be necessary to correct
these conditions.

CHAPTER 9 System alarms and
messages
The Medtronic MiniMed 2007D Implantable Insulin Pump System is equipped
with various alarms and messages that ensure the correct function of the system.
The Implantable Insulin Pump alarm system will “beep” when certain conditions
occur. The beeps are designed to be audible through the skin and alert the patient
that the Pump needs attention. For severe alarm conditions the Pump will alarm 4
tones each minute for 10 minutes then, 4 double tones each minute for 10 min-
utes and repeat the pattern. Upon hearing the alarm, the patient must communi-
cate with the PPC, to determine the alarm condition. The alarm can be cleared by
pressing SEL then ACT. The following descriptions explain the alarm conditions
the system may encounter.
The PPC has three types of alarms: audible, vibrate and visual alarms. The chap-
ter will describe for each alarm condition, which screen message appears and the
vibrate or audible alarm associated with it.
Two audible or vibrate alarm types are used:
Alarm Type 1:
If the PPC is set to “vibrate”, the vibrator will be turned on for 3 seconds every
minute for 30 minutes.
If the PPC is set to “audible”, the PPC will beep 6 times every minute for 30 min-
utes. If the alarm is not cleared in 30 minutes, the PPC will beep 6 alternating
tones. The PPC will continue to do so every minute.
Alarm Type 2:
If the PPC is set to “vibrate”, the vibrator will be turned on for 3 seconds every
30 minutes while the condition exists.
If the PPC is set to “audible”, the PPC will beep 3 times every 30 minutes while
the condition exists.
Some alarms can be cleared by pressing SEL then ACT.
System alarms and messages
90
Pump alarms
Alarm feedback
The Alarm Feedback function allows the user to verify the Pump and Pump
alarm are operating normally. Physicians can also use Alarm Feedback to mea-
sure the time intervals between Pump strokes to verify accurate insulin delivery.
When Alarm Feedback is programmed “YES”, the Pump will beep on each of the
first five Pump strokes:
• Following a change in the delivery regimen, for example when completing
a meal Bolus and then changing to a Basal Rate, or at the start of a bolus.
• After the Alarm Feedback function is programmed “YES.” Alarm
Feedback will stay on until programmed back to “NO.”
Pump low battery
The Implantable Insulin Pump battery is designed to last approximately ten years
during conditions of normal use (see Chapter 11 for Technical Specifications).
Battery life may vary somewhat depending upon a user’s insulin delivery
requirements. When battery energy becomes low, a voltage sensor in the Pump
will trigger the Pump Low Battery Alarm. A Pump Low Battery Alarm indicates
there is approximately eight weeks of battery energy remaining.
The Pump Low Battery alarm can be cleared and the Pump will continue to oper-
ate normally. However, users should be instructed to report the alarm immedi-
ately to their physician. A Pump replacement or resumption of conventional
insulin therapy should then be scheduled.
Depleted pump battery
When there is no longer sufficient battery energy to power the Pump, the Pump
Low Battery Alarm will cease and insulin delivery will stop. Alternate insulin
therapy must be initiated.

CHAPTER 10 Troubleshooting Pump
System under-delivery
Potential under-delivery of insulin by the Medtronic MiniMed 2007D Implant-
able Insulin Pump System may result in an increase in daily programmed insulin
usage, difficulty maintaining euglycemia, occasional hyperglycemia, and prob-
lems calculating refill accuracy. This chapter describes how to diagnose potential
Pump System problems that may cause insulin under-delivery, and offers poten-
tial Pump and Catheter solutions to correct for under-delivery.
Diagnostic procedures
When refill procedures reveal the possibility of a Pump System under-delivery
problem, diagnostic procedures must be performed to verify if there is a problem
with either the Pump or Catheter. The Stroke Volume Measurement Procedure
tests Pump function, while the Pressure Measurement Procedure tests Catheter
patency. These diagnostic procedures should be performed according to the steps
outlined in Appendix G.
Under-delivery caused by backflow
Backflow results in the inverted flow of insulin through the Pump System. Back-
flow is caused by insulin deposits that compromise valve integrity, and allow the
negative reservoir pressure (vacuum) to pull insulin back into the reservoir. To
compensate for this under-delivery, the user can program appropriate increases in
their basal rates and bolus amounts.
Backflow conditions are characterized by increases in daily programmed insulin
usage, difficulty in maintaining euglycemia, increasingly negative refill accuracy
and sometimes hyperglycemia. Confirm a backflow condition by performing the
Stroke Volume Measurement Procedure. Then rinse the Pump System with
NaOH solution to dissolve insulin deposits, following the Pump Rinse Procedure
outlined in Appendix E.
Troubleshooting Pump System under-delivery
98
Under-delivery caused by catheter occlusion
Under-delivery caused by Catheter occlusion can occur either abruptly or gradu-
ally. The insulin usage and clinical symptoms are identical to those of Pump
under-delivery. Confirm a Catheter occlusion condition by performing a Pressure
Measurement Procedure. Then perform the following procedures to clear the
occlusion:
• First, flush the Catheter by using the Side Port Catheter Flush Procedure
outlined in Appendix F.
• If the Flush Procedure is unsuccessful, replace the Catheter.
Catheter replacement surgery should be performed in a manner similar to the ini-
tial Pump System implantation. PPC initialization will not be necessary. How-
ever, after the Catheter replacement, Pump function and delivery verifications
must be performed.

APPENDIX D Precautions and general
procedures
Special note and precautions
Before beginning the implant, refill, stroke volume measurement, rinse/flush, or
pressure measurement procedure, carefully read this Appendix and keep the
information in mind as you perform each procedure.
1. All procedures should be performed using ASEPTIC TECHNIQUE.
2. Air in the Pump System has been shown to be a significant contributing
factor to aggregation of insulin. Proper degassing of all solutions that enter
the Pump is essential. Read the insert in the refill kit packaging about the
degassing procedure.
3. When using the refill kit, never release the syringe-locking ring while there is
a vacuum within the refill syringe. The plunger of the syringe will snap back
forcefully and may rupture the syringe and eject the contents.
4. It is important that the syringe needle is perpendicular to the fill port to
prevent binding when entering or exiting.
5. The Side Port Catheter attachment site contains up to 20 units of INSULIN.
The distal portion of the Catheter and the tubing can contain up to 13 units of
INSULIN. However, the INSULIN in the Pump fluid pathway and the side
port receptacle can be cleared by following the procedure to pull RINSE
BUFFER through the side port. During a flush procedure to push out a
catheter tip blockage, the 13 units in the distal catheter will be delivered to
the patient. The 13 units can be managed by programming continuous bolus
amounts prior to the procedure, or with the use of oral or IV glucose as
needed during the procedure. Individual patient response to INSULIN bolus
amounts must be considered.
6. Patient blood glucose monitoring must be performed during, and up to one
hour after the procedure. Oral and intravenous glucose should be available
for glycemic management.
110
7. After the flush procedure, at least 13 units of RINSE BUFFER will remain in
the distal portion of the catheter. Programmed bolus amounts to remove the
RINSE BUFFER may be completed before the patient leaves the clinic. A
prescribed INSULIN basal rate should be programmed when the system is
clear of RINSE BUFFER.
8. Never push down on the plunger to fill the Pump. When the Medtronic
MiniMed refill needle is properly seated in the fill port, the vacuum in the
reservoir will draw the fluid from the syringe.
9. Each step of the procedure will list the syringes and appropriate fluids needed
for that step. It is suggested that the syringes be prepared and labeled prior to
the start of the procedure.
10. The Side Port Catheter is intended to be accessed only during the implant
procedure, the combined rinse/flush procedure, the catheter flush procedure,
and for diagnostic procedures. The catheter is not intended to provide access
to the peritoneum for bolus injections of fluids or for withdrawal of body
fluids.
General procedures
Before beginning any of the procedures, be sure you are familiar with the general
techniques for locating the Pump fill port and the Side Port Catheter, accessing
the Pump inlet, venting the refill syringe, and preparing the syringes.
111
Locating the pump fill port and the side port
Figure 15: Template and placement
1. Locate the Pump, then aseptically prep and drape the Pump area. Use topical
or local anesthetic if desired.
2. To locate the Pump fill port, located in the center of the Pump, align the
sterile template (MMT-4106) over the Pump by palpating the Pump
circumference. Then insert an 18 gauge needle into the central Pump fill port
as shown in Figure 15 above.
3. To locate the side port, palpate around the circumference of the Pump. It is
helpful to grasp the side port between the thumb and index finger when
aligning the template.
4. Using the template as a guide, insert the second 18 gauge needle into the side
port as shown. The side port can be accessed by inserting the guide needle
just inside the outer edge of the side port connection. This outer edge is
raised around the outer aspect of the side port, in order to help guide the
needle into the port.

Placement on Skin with
Guide Needles in Position
112
Accessing the pump inlet
(See Figure 16.) To enter the Pump fill port or the side port, make sure the refill
syringe stopcock is closed, then pass the Medtronic MiniMed refill needle
(MMT- 4102) through the 18 gauge guide needle. Pull back slightly (approxi-
mately 2 mm) on the guide needle to allow the Medtronic MiniMed refill needle
to enter the Pump fill port or the side port. The refill needle entry opens the inlet
valve of the Pump fill port.
After passing through the septum and seating in the valve, you can feel the
increased force, about 0.5 pounds, required to move the valve 0.5 millimeter to
open. Maintain this downward pressure in the pump fill port to ensure that the
inlet valve remains open. In the case of the side port, a downward pressure is not
required after the needle is completely inserted.
Figure 16: Inlet valve
113
Venting the Medtronic MiniMed refill syringe (optional)
In order to fill the Pump, it may be necessary to vent the headspace in the
Medtronic MiniMed refill syringe. Refill syringes do not have lubricant on the
syringe housing or on the plunger tip. Some syringes may be “sticky” and require
the venting procedure described below to assist the vacuum in the Pump to over-
come this condition.
To vent, hold the syringe with the refill needle pointing down. Vent the syringe
headspace by pulling back firmly on the plunger until the second sealing ring on
the rubber cap passes beyond the vent hole as shown in Figure 17.
Figure 17: Venting the refill syringe
NOTE: Be sure that the plunger is retracted far enough
that the vent hole is exposed. The syringe must
be held with the needle facing down and used
within 10 minutes once it is vented. If this time
limit is exceeded, repeat the degassing
procedure and re-vent.

the syringe in place for the next step.
125
Equilibrate and pull insulin through system
The reservoir pressure in the Pump is equilibrated with outside ambient pressure
and INSULIN is pulled through the fluid system. This procedure uses the follow-
ing volumes in syringes 6 and 7:
• Syringe 7 with residual INSULIN from previous step.
• Syringe 6 with 5 ml solution. To perform this procedure with syringes 6 and
7, follow the steps below:
Syringe 7: Insulin - Residual
1. Maintain syringe 7 with approximately 10 ml of residual INSULIN in the
Pump fill port. Verify that the stopcock on syringe 7 is open.
Syringe 6: Insulin - Residual
1. Prime the syringe 6 needle. Close the stopcock.
2. Obtain a vacuum in syringe 6 by pulling back on the plunger until it locks.
Press the lock into the plunger groove to be sure it is firmly secured.
3. Enter the side port with syringe 6 - stopcock closed.
4. Open the stopcock on syringe 6.
5. Using the PPC, program and deliver a 4 unit bolus.
6. Observe syringe 7. If the level of INSULIN approaches 2 ml, close the
stopcock to prevent air from entering the Pump. Observe syringe 6. At least 1
ml of INSULIN must pass into syringe 6 to assure removal of all the RINSE
BUFFER from the side port. If less than 1 ml enters, repeat the bolus from
Step 6, some Pumps may require 3 successive boluses to obtain 1 ml.
7. Close both stopcocks. Remove syringe 7 from the Pump. Set aside the
syringe to be weighed.
8. With the stopcock closed, remove syringe 6 from the side port. Syringe 6 will
have a vacuum from the previous step. Enter the Pump fill port with syringe
6 and open the stopcock to remove 2 ml. This will restore the negative
pressure safety feature of the Pump.
9. Close the stopcock, remove syringe 6 from the Pump, and set it aside to be
weighed.
126
Remove guide needles and record fill amount
At this point, the 18 gauge guide needles should be removed and the refill
amount should be calculated and recorded. Follow the steps below:
1. Remove the 18 gauge guide needles. Apply pressure to the needle insertion
sites.
2. Weigh syringes 6 and 7 and record on the refill form. Subtract the combined
weight from the weights obtained in step 14 of the section, “Remove RINSE
BUFFER and Fill with Insulin.” The result is the new refill amount.
3. Record the extracted and new refill amounts in the PPC.
Program new basal rate
Using the patient’s PPC, cancel the SUSPEND mode, to return to the normal
patient’s basal rate and modify if needed.
