need to use the procedure described in Appendix G, after
the Catheter has been attached.
3. Listen for five beeps and observe that fluid is being pumped from tub-
ing 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.
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/tub-
ing assembly horizontal. (see Figure 8).
Figure 8: Testing Pump Stroke Volume with a Pipette
7. Note the exact location of the fluid meniscus in the pipette.
8. Measure the stroke volume by noting the volume displaced by a mini-
mum of 10 pulses. Record the total volume delivered and the number
of pulses on the Implant Worksheet. Divide the total volume deliv-
ered 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 may be a precision sealing surface in
the connector that will 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 pack-
age and document the serial number on the Implant Worksheet.
2. Using the last insulin syringe (IN2) from the Pump preparation proce-
dure, 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 out-
let. Remove the syringe.
3. Remove the plastic tubing and tubing retainer from the Pump outlet.
Remove the tubing retainer, by rotating it one-quarter turn clockwise
to disengage it from the connector flange.Then lift and remove the
tubing and retainer together from the Pump outlet.Dispose of the tub-
ing and retainer.

Step 4 Inspect the outlet of the Pump for debris. Debris, espe-
cially 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.
Use caution when removing debris from
the outlet of the Pump. There is a precision
rubber seal on the outlet that will be dam-
aged by handling with surgical instru-
ments.
Step 5 Pull the locking bar out and gently push the Catheter
straight down onto the Pump outlet. Never twist the
connector.

Step 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.)
Step 8 Using the IN2 refill syringe, enter the Catheter side port
cone and push a small amount of INSULIN out the Cath-
eter tip. Verify that no insulin flow is observed at Pump/
Catheter interface. Remove and reseat Catheter if flow is
noted. Remove the syringe.
Step 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.)
Step 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 sur-
geon 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.

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 subcutane-
ous 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 anes-
thesia. 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 loca-
tion 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 per-
formed to create a pocket large enough to accommodate the Pump.
Meticulous hemostasis should be established with electrocautery.
Figure 11 indicates a possible Pump placement and corresponding inci-
sion sites.
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
recommended, as it will prevent migration, rotation or inversion in the
pocket and possible dislodgment of the Catheter.

Catheter placement
The Catheter is not designed to be tunneled subcutaneously. The Catheter
insertion should be at the extreme edges of the Pump pocket.
At a site not directly beneath the Pump, the layers of abdominal muscula-
ture 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 reinforced 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. Inter-
rupted absorbable sutures should be used to approximate the subcutane-
ous 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 capsule 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-opera-
tive complications 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 repro-
grammed 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 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 identifica-
tion 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 approx-
imately 6,000 units of insulin 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 messages 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 delivery rate of the Pump.
The Pump refill procedure should always be
scheduled in advance of PPC “low reservoir” or
“empty reservoir” messages.

Introduction 99
Prepare for pump refill
NOTE: Before beginning any refill, rinse, flush, or pres-
sure measurement procedure, carefully read
Appendix D, Precautions and General Proce-
dures.
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 reservoir 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 work-
sheet (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 proce-
dures.

CHAPTER 6 Explanting the Pump
System
Explant considerations
When the battery in the Pump is depleted or if acceptable glycemic con-
trol cannot be achieved, it may become necessary to explant the Pump
system.
Prior to explantation, it may be possible to perform interventions that
could correct certain conditions. These procedures are described in
Appendices E and F.
If all appropriate interventions have been exhausted without an acceptable
outcome, please contact MiniMed prior to scheduling a Pump explanta-
tion.
Returning devices/components to MiniMed
Explanted Pumps and Catheters or other components should be returned
to MiniMed for evaluation. Please call MiniMed and obtain a Returned
Materials Authorization (RMA) 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 con-
tainer should be water tight. Chemical and reliability analysis require that
the device not dry out during transportation.

Elevated anti-insulin antibodies
The result of clinical investigations suggest a small population of patients
may develop anti-insulin antibodies when using the MiniMed 2007
Implantable Pump System and HOE 21 PH 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.
Environmental conditions
The Medtronic MiniMed 2007C 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 MiniMed when in doubt if
certain environmental exposure will affect the pump.
DO NOT EXPOSE THE MINIMED 2007 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 rotat-
ing 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).
The Medtronic MiniMed 2007C 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

Warnings And Precautions
112
elevations above 8,000 feet or 2,400 meters 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.
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 ban-
dage or a reduction in the patient’s physical activity until the pump pocket
reheals completely.
• Exposure to Extreme Body Temperatures
Exposure to elevated body temperature in excess of 104°F (40°C) will
compromise the negative pressure reservoir safety feature of the MiniMed
2007 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.

Precautions 113
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 or EtO.
The Template MMT-4106 may be resterilized using steam autoclave or
EtO. 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.
Precautions
Emergencies and the use of conventional insulin supplies
Physicians should advise patients who wear the Medtronic MiniMed
2007C Implantable Insulin Pump System how to deal with emergency
conditions such as hyperglycemia. Patients should always carry conven-
tional 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, immediately perform a SELF
TEST to check the displays for proper operation. If the PPC does not dis-
play 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 micro-

electronics. If either situation occurs, contact MiniMed immediately and
arrange for the repair or replacement of the PPC. If the PPC is acciden-
tally 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
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 pro-
vide some control of patients’ ability to program their insulin regimens,
and to avoid overdosing.
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, stan-
dard medical X-rays, cellular phone, and radiowaves.

Prevention
The majority of adverse reactions in patients using the Medtronic
MiniMed 2007C Implantable Pump System can be prevented by teaching
patients dependable blood glucose monitoring. The patient plays a signif-
icant role in diagnosing and correcting Pump System performance prob-
lems. Should Pump performance change, the patient would be able to
detect a change in blood glucose levels.
Patients should be instructed to contact
their physician’s office, if they experience
unresolvable difficulties with the Pump
System. Emergency patient visits and
diagnostic procedures may be necessary
to correct adverse conditions.
