1CHAPTER 1 DescriptionIntroductionThe Medtronic MiniMed 2007D Implantable Insulin Pump System, shown inFigure 1, brings together sophisticated new technologies to provide continuousintraperitoneal insulin therapy for patients with Insulin Dependent DiabetesMellitus (IDDM). The development of the Medtronic MiniMed 2007DImplantable Insulin Pump System is the result of years of cooperative researchand development between Medtronic MiniMed and: • The Johns Hopkins University, Applied Physics Laboratory• U.S. National Aeronautics and Space Administration, Goddard SpaceFlight Center. U.S. National Institutes of HealthFigure 1: Implantable Insulin Pump and Personal Pump Communicator (PPC)

Description2This manual is intended for use by the physician, surgeon, nurse specialist and allother members of the healthcare team who care for patients with the MedtronicMiniMed 2007D Implantable Insulin Pump System.The Medtronic MiniMed 2007D Implantable Insulin Pump System can be usedwith special U-400 insulin formulations specifically labeled for use with theMedtronic 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 indetail in the following sections.

Description 3Implantable Insulin PumpThe Implantable Insulin Pump (Pump) is a round disc, 8.1 cm (3.2 inches) indiameter, 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 abiocompatible metal used in many types of implantable medical devices. Atangential Side Port Catheter is attached to the Pump prior to implant, using alocking connector (see Figure 2).Figure 2: The Implantable Insulin PumpThe Implantable Insulin Pump is an advanced insulin infusion device withsophisticated microelectronics. It delivers a special insulin medication, using apulsatile solenoid pumping mechanism that is hermetically sealed inside thebiocompatible titanium case. Insulin delivery rates and profiles are programmedusing an external device, the Personal Pump Communicator (PPC). Specificinformation on the Implantable Insulin Pump features is outlined in the followingsections.

Description4The Pump has six major components. These components are outlined below: • medication reservoir• pumping mechanism• microelectronics• antenna• battery • tone transducerOther components of the Pump include the inlet valve, fill port, septum,cyclopentane gas and 20µm filter. Figure 3 shows the interior components of thePump.Figure 3: Interior of the Implantable Insulin PumpThe Medication Reservoir stores approximately 15 ml or 6,000 units of aspecial U-400 insulin. Depending on an individual’s insulin requirements, themedication reservoir is refilled once in approximately every two to three months.The medication reservoir is maintained at a negative pressure (vacuum) at alltimes to allow for safe and reliable filling. This vacuum prevents any risk ofinsulin leakage in the event of a breach in the Pump case or reservoir. Thereservoir is refilled with a special needle (Medtronic MiniMed Refill NeedleMMT-4102). The fill port has a 20 micron filter to prevent particulate materialfrom entering the Pump and a redundant septum and valve configuration toprevent entry of body fluids.

Description 5The Pumping Mechanism is a solenoid-operated, hermetically-welded pulsatilesystem. The pumping mechanism is designed to seal automatically to preventleakage both into and out of the reservoir under physiologic temperatures andpressures. The mechanism is designed to provide an insulin delivery accuracy ofwithin 10% from its labeled stroke volume. Individual Pumps are calibrated toone of seventeen different stroke volumes, ranging from 0.42 µL to 0.58 µL perstroke, in increments of 0.01 µL.The Microelectronics act as the brain of the Pump. The microelectronics containtwo microprocessors which monitor and control all pump-stroke activity. Allcommands delivered from the PPC via RF telemetry to the Pump are thenacknowledged back to the PPC. The Pump has a large memory which storesPump specifications and programming history.The Antenna receives radiowaves from the PPC and delivers PPC programmingcommands to the Pump microelectronics.The Battery is a custom-made lithium carbon mono-fluoride power cell, whichsupplies energy to the pumping mechanism and microelectronics. It is similar tobatteries 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. Thesebeeps are designed to be audible through the skin and can be set with the PPC toone of two volumes. The Pump can also be programmed to emit beeps that signala programmed change in the medication delivery rate.Radio-Opaque Identification is featured in the Implantable Insulin Pump. Inthe event of an emergency, the name of the manufacturer and the Pump modelnumber can be identified with an x-ray.Insulin medicationOnly specially formulated U-400 insulins that are specifically labeled for usewith the Medtronic MiniMed Implantable Insulin Pump System can be used inthe model 2007D Pump.These special U-400 insulins are supplied in 10mL vials.

Description6Side Port CatheterThe Side Port Catheter (Catheter) transports insulin from the Pump into anindividual’s peritoneum where it is absorbed. The Catheter is made ofpolyethylene-lined silicone rubber, which is biocompatible with subcutaneousand intraperitoneal tissues and supports the stability of the special insulin. TheCatheter is designed with two perpendicular sections: a proximal subcutaneoussection which attaches tangentially to the Pump with a locking connector, and adistal 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 Pumpoutlet, in order to perform the non-surgical interventions and diagnosticprocedures described in Appendices E, F and G. The side port allows for theintroduction of a needle and small syringe to clear Catheter obstructions usingpressures up to 100 psi. It also allows for the introduction of a needle to verifyPump stroke volume.Figure 4: The Intraperitoneal Catheter and Side Port

Description 7Personal Pump Communicator (PPC)The Personal Pump Communicator (PPC) is the hand-held component of theMedtronic MiniMed 2007D Implantable Pump System (see Figure 5). The PPC allows the physician and patient to communicate with the Pump bytransmitting radio frequency messages when the PPC is held within 3” of thePump. Additionally, the PPC stores important programming information in itsmemory.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 differentpatterns)• Deliver or suspend an immediate, Square Wave, or Dual Wave Bolus ofinsulin• 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 recordcertain programming data from the Pump. The recorded information is accessibleand can be displayed on the screen.

9CHAPTER 2 Indications and contraindicationsIndications for useThe Medtronic MiniMed 2007D Implantable Insulin Pump System is indicatedfor intraperitoneal administration of exogenous insulin in patients with diabetesmellitus.The model 2007D Pump can only be used with special U-400 Insulinformulations specifically labeled for use with the Medtronic MiniMedImplantable Insulin Pump Infusion System.Contraindications for use The Medtronic MiniMed 2007D Implantable Insulin Pump System iscontraindicated in patients who:• are unwilling or unable to monitor their blood glucose level at least fourtimes per day.• are unwilling or unable to make programming modifications to the Pumpbased 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 theirtreating physician and other healthcare providers. • reside at or travel (other than by pressurized commercial aircraft) atelevations 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 theirdosage requirements (approximately once every 90 days).• present or have a history of sensitivity to titanium alloy, polysulfone orsilicone materials used in the implanted components of the system.

Indications and contraindications10Possible adverse effectsThe model 2007D is essentially identical to the model 2007C Pump except forthe change in gas needed to maintain negative pressure in the reservoir.Evaluation of components used in the Medtronic MiniMed 2007C system hasspanned a period of approximately 4 years and involved approximately 380patients 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 apotential for such an occurrence.The following are specific adverse effects which should be understood by thephysician and explained to the patient. These do not include all adverse effectswhich can occur with surgery in general or with the use of this device, but areimportant considerations, particularly in the treatment of diabetic patients. Thegeneral surgical risks, as well as operative site cosmetic risks, should beexplained 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

11CHAPTER 3 Personal Pump Communicator (PPC)IntroductionThe Personal Pump Communicator (PPC) has a comprehensive set of program-ming features to control the Implantable Insulin Pump. The PPC cannot be usedby the patient until it has been initialized by the healthcare professional. Thischapter of the manual is divided in two parts:The first part (Part 1) will describe the PPC/PUMP system initialization processthat will be performed the day prior to implant.The second part (Part 2) will describe how to use the additional features that thehealthcare professional or patients can activate.PPC iconsAfter 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 areas 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)12Certain features of the PPC such as programming and dosing limits can be setonly by the healthcare professional in a password-protected mode called theSupervisor Mode. Information pertaining to initializing the PPC and entering thePPC Supervisor Mode is not included in the Patient User Manual.PPC buttonsCommunicating with the PumpPlace the PPC near the Pump when the screen displays,“PPC COMMUNICATING.” The word "COMMUNICATING" will blink asindication of successful communication. If a communication link between thePPC and Pump is not established, a “TELEMETRY COMM ERROR 3” messagewill appear. The PPC will beep six times once every minute until the screen isacknowledged by pressing SEL and ACT. The screen will then display “PPCCOMMUNICATING” again.After a communication is established between the PPC and Pump and programinformation is successfully transferred to the Pump, the PPC will beep once andreturn to the Time/Date screen.• Always press the PPC buttons slowly and firmly. Wait until the screenchanges before pressing the button again. • A flashing value on the screen means that the value is activated, and can bechanged by pressing the arrow buttons.SEL(Select) The SEL button steps through each of the displays and menus.ACT(Activate) The ACT button activates programming changes in the Pump, new information to be entered into the PPC memory, and alarms to be turned off. As a safety check, ACT must be pressed to complete any programming changes. A single beep is heard after activating a change.or (Up or Down Arrows)The or arrows allow changes in the screen settings. Pressing once will find the next highest setting, and pressing once will find the next lowest setting. Holding down either button will rapidly scroll through the list of preset values. Desired values can then be programmed by pressing ACT.Sound Icon(Up Arrow) When the Audio Bolus feature is turned on, pressing allows programming an Audio Bolus.Light Icon(Down Arrow) From the main operating screen, pressing once will turn on the backlight. The backlight allows the Pump to be programmed in the dark. The backlight will turn off automatically after four seconds after the last button press.

Personal Pump Communicator (PPC) 13• The PPC cannot be turned off. Once the battery has been installed, the PPCis on and remains on until the battery is removed.• Certain types of Radio Frequency (RF) generating equipment could affectPPC communication with the Pump. If you are experiencingcommunication difficulties, change locations.• The time and date settings must be correct to ensure appropriate calculationof insulin delivery and display of daily totals and activity history.Install/Replace the main batteryThe battery used to power the PPC is a 1.5V AA alkaline. The life of the batteryis approximately 4 weeks during normal usage conditions. • Locate the battery door on the back of the PPC.• Slide the locking bar to the left.• Push the middle part of the PPC box (under the battery door) and lift bygently pulling up the battery door to unlatch.• Remove the old battery, noting the polarity. The screen will be blank.• Position the new battery so the + and - markings on the battery match thepolarity diagram in the battery compartment.• Close the battery door.• Slide the locking bar to the right.• The PPC screen will reappear within 30seconds:1. The PPC will beep 6 times, and after a fewseconds, the screen will display“CHECK PUMP STATUS”.PPCPUMP8 102 100 __ __ __08:26CHECKPUMP STATUSJAN O2

NOTE: When the PPC displays “PPCLOW BATTERY”, the message can be cleared, andprogramming continued. There should be sufficientenergy in the battery to communicate with the Pump a fewmore times, but the battery should be changed as soon aspossible.NOTE: If while programming the PPC, the screen goes blank, thePPC beeps six times and then the “CHECK PUMPSTATUS” message appears, the battery needs to bereplaced.PPCCOMMUNICATING

Personal Pump Communicator (PPC) 15Part 1: PPC/Pump system initializationThe Implantable Insulin Pump arrives from Medtronic MiniMed with preset fac-tory default values. During the initialization process these preset values aredownloaded into the PPC memory. The preset values can then be changed by thehealthcare professional, allowing the system to be personalized for each patient.The factory default values are as follows:Initialize the PPCWhen the healthcare professional receives a new PPC it must be “married” to thePump. Following are the basic steps used to initialize a Pump System the dayprior to implant: 1.

Listen for five beeps and observe that fluid is being pumped from tubingattached to the Pump outlet.4. Attach the 18 gauge needle (from the 3 ml syringe filled with RINSEBUFFER) to the plastic tubing from the Pump outlet.5. Remove the 3 ml syringe and fill the needle hub.

Pump implantation60Figure 8: Testing Pump stroke volume with a pipette6. Insert the pipette into the hub. A meniscus of fluid will be present in thepipette. This should be done on a flat surface with the pipette/tubingassembly 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 of10 pulses. Record the total volume delivered and the number of pulses on theImplant Worksheet. Divide the total volume delivered by the total number ofpulses used to deliver that volume. The volume per stroke must be between0.40 and 0.60 µL. Record this value on the Implant Worksheet.Prepare the Side Port CatheterThe Side Port Catheter (“Catheter”) is attached to the Pump before implantation;however, it must be primed with INSULIN and inspected before being attachedto 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 strokevolume has been verified. Remove the Catheter from its sterile package anddocument 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 theconnector end of the Catheter. This primes the proximal portion of theCatheter and cleans any debris from the connector outlet. Remove thesyringe.!WARNING

Pump implantation 613. (See Figure 9.) Remove the plastic tubing and tubing retainer from the Pumpoutlet. Remove the tubing retainer by rotating it one-quarter turn clockwise todisengage it from the connector flange. Then lift and remove the tubing andretainer together from the Pump outlet. Dispose of the tubing and retainer. Figure 9: Tubing and retainer removalView ARotate tubing retainerView BPull tubing retaineroff pumpView CTubing and retainerremoved

Pump implantation624. Inspect the outlet of the Pump for debris. Debris, especially fibers, left in thefluid path will compromise the function of the Catheter check valve. Rinsethe outlet tube of the Pump with water from a syringe, if necessary. Avoidwiping 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 thePump outlet. Never twist the connector.6. Only after the Catheter is seated, squeeze the connector (see Figure 10, item1), 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 otherhand.Figure 10: Proper attachment of the Side Port Catheter to Pump7. Verify the Catheter is securely attached to the Pump. Look into the connectorand observe the position of the locking bar with respect to the Pumpconnector 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 asmall amount of INSULIN out the Catheter tip. Verify that no insulin flow isobserved at the Pump/Catheter interface. Remove and reseat the Catheter ifflow is noted. Remove the syringe.9. Confirm insulin delivery from the tip of the Catheter and note it on theImplant Worksheet. The INSULIN will form a dome on the tip of theCatheter. Pulsatile delivery will not be obvious. If the priming bolus hasalready ended, program an immediate bolus (about 20 units) to confirmdelivery. (This bolus may be canceled after delivery is verified.)

Pump implantation 6310. At the end of the bolus, rinse the outside of the Pump thoroughly with sterilewater to remove traces of INSULIN. The Catheter tip should not be placed inthe water. Protect the Pump with sterile drapes until the surgeon is ready toimplant it. Verify that the priming bolus is finished or canceled prior to theimplantation.The Pump and Catheter are now ready for implantation.

Pump implantation64Performing the surgical procedurePre-operative evaluationThe Pump implant depth should not exceed 5 cm (2 inches) beneath the surfaceof the skin. If the Pump is implanted too deeply in the subcutaneous tissue it maybe difficult to access the refill port.Formation of the pump pocketPump implantation can be performed either under local or general anesthesia.After satisfactory anesthesia, a pre-selected abdominal site is prepped and drapedin the customary surgical method.A transverse or longitudinal incision is made and deepened through the skin andsubcutaneous tissue. Care should be taken in choosing the location of the incisionso the suture line is next to but not over the Pump inlet fill port or the Catheterside port. A subcutaneous blunt dissection is performed to create a pocket largeenough to accommodate the Pump. Meticulous hemostasis should be establishedwith electrocautery. The Pump is secured to the fascia of the abdominal musculature using the threesuture 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 65Figure 11: Example of Pump placement

Pump implantation66Catheter placementThe 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 aredivided to expose the peritoneum. Concentric purse string sutures are placed andthe peritoneum is exposed with a 1 cm incision. The distal tip of the Catheter isplaced in the peritoneal space. The flange of the Catheter is sutured firmly to thefascia 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 Catheteritself.Never trim or cut the tip of the Catheter.The implant site should be irrigated with an antibiotic solution. Interruptedabsorbable sutures should be used to approximate the subcutaneous tissues andthe skin closed with a running subcuticular absorbable suture. The wound isdressed using standard surgical technique. At the end of the surgery, place anabdominal 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 willobtain a better cosmetic result and minimize the post operative swelling.!WARNING

Pump implantation 67Post-operative managementPost-operative hospitalizationAfter implantation, the surgical incision should be inspected for any signs ofunusual swelling, tenderness, pain, or drainage. Potential post-operative compli-cations include Pump pocket seroma, wound dehiscence, wound infection, andcatheter dislodgment.Length of post-operative hospitalization depends upon how rapidly the patientadjusts to the Pump and how quickly blood glucose levelsstabilize. During post-operative hospitalization, the Pump can be reprogrammedto accommodate the needs of the patient. As post-operative stress decreases,insulin requirements may decline. It may be necessary to make several changesin insulin delivery rates during the first few days following implantation.Patients must be thoroughly educated in all aspects of follow-up care with thePump. The Medtronic MiniMed Patient Manual should be used to supplementpatient 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-raysThe Catheter has been designed with a radio-opaque stripe for identification afterimplantation. A lateral and anterior X-ray is recommended after implantation tolocate and document the position of the Catheter. This radiograph should be keptwith the patient’s records for future reference.

Pump implantation68

69CHAPTER 5 Pump refill procedureIntroductionInitial appointments for Pump Refills should be made with patients at the time ofimplantation. Subsequent appointments should be made in advance, normallyduring 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 orderto maintain the physical stability of the insulin, the Pump must be refilled at amaximum 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 reservoirmessage will appear when the PPC calculates that 400 or fewer units (1 ml) ofinsulin 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.!WARNING

Pump refill procedure70Supplies and solutionsThe refill kit (MMT-4105) is intended exclusively for use with theMedtronic MiniMed 2007D Implantable Insulin Pump System. The refill kit con-sists of a specially designed syringe and stopcock for removing fluids from andplacing fluids into the Pump. Use only refill needles (MMT-4102) available fromMedtronic MiniMed to perform all Pump refill procedures. This 22 gauge needle,featuring a rounded, lubricated tip and a beveled side hole, has been speciallydeveloped 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.)• Four (4) 18 Gauge Regular Bevel NeedlesSolutions:• One (1) 10 ml Vial, Rinse Buffer Solution, MMT-2008 • Two (2) 10 ml Vials, U-400 Insulin, stored at room temperature for aminimum of 10 hours prior to surgery.!WARNING

Pump refill procedure 71Prepare for pump refillNOTE: Before beginning any refill, rinse, flush, or pressuremeasurement 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 insulinmedication 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 therefill 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 beperformed using your institution’s standard operating procedures.!WARNING

79CHAPTER 6 Explanting the Pump System Explant considerationsWhen 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 MiniMedExplanted Pumps and Catheters or other components should be returned toMedtronic MiniMed for evaluation. Please call Medtronic MiniMed and obtain aReturned Sales Order (RSO) number prior to each return.Explanted devices must be sealed in an appropriate biohazard container andpacked with a gauze pad soaked with sterile saline. The shipping containershould be water tight. Chemical and reliability analysis require that the devicenot 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 watertight document package. Put the RSO number on the shipping label.

81CHAPTER 7 Warnings and precautions WarningsThe Physician should be completely familiar with the function of the Pump,Catheter, and PPC prior to use. Patients should be provided a complete copy ofthe Patient Manual and have demonstrated the ability to program the PPC,recognize and respond to safety alarms, and take care of the device prior todischarge.Only special U-400 insulins specifically labeled for use with the MedtronicMiniMed Insulin Infusion Systems may be used in the Medtronic MiniMed2007D Implantable Insulin Pump. Use of other insulin types may cause damageto the Pump mechanism resulting in impaired insulin delivery or Pump failure.Any unauthorized changes or modifications made to any component of theMedtronic MiniMed 2007D Implantable Insulin Pump System may preventeffective use of that and other components.ElectrotherapyThe Medtronic MiniMed 2007D Implantable Insulin Pump System has beentested in close proximity with electrosurgical, electrocoagulation, and cardiacdefibrillation medical equipment. Typical use of this type of device has notaffected 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 areoperating properly. If the system is not performing correctly, contact MedtronicMiniMed.

Warnings and precautions82Diagnostic ultrasound The Medtronic MiniMed 2007D Implantable Insulin Pump System has beentested during diagnostic ultrasound procedures. These procedures have no effecton Pump performance. However, patients should be instructed to test the Pumpfunction (e.g., self test) after such procedures to determine that the Pump andPPC are operating properly. If the system is not performing correctly, contactMedtronic MiniMed.Ultrasound therapyThe Medtronic MiniMed 2007D Implantable Insulin Pump System should not beexposed to therapeutic ultrasound procedures such as lithotripsy. Exposure toultrasound therapy may damage the Pump, and not be immediately apparent.Diagnostic radiationThe Medtronic MiniMed 2007D Implantable Insulin Pump System has beentested during diagnostic radiation procedures, such as Computed Tomographyand 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 suchprocedures to determine that the Pump and PPC are operating properly. If thesystem is not performing correctly, contact Medtronic MiniMed.Elevated anti-insulin antibodiesThe results of clinical investigations suggest a small population of patients maydevelop anti-insulin antibodies when using the Medtronic MiniMed 2007DImplantable Pump System and U-400 insulin. Patients with multiple autoimmunedisorders may be more susceptible to developing high titers of anti-insulinantibodies, which in turn may cause symptoms. There was no correlationbetween length of exposure to the study drug and the resultant titer of anti-insulinantibodies. Elevated levels of anti-insulin antibodies alone have been proven notto interfere with diabetes management using continuous intraperitoneal insulininfusion with this system.

Warnings and precautions 83Environmental conditionsThe Medtronic MiniMed 2007D Implantable Insulin Pump System should not beexposed to extreme electrical or magnetic fields. Although it is not possible toinclude every environmental condition that may affect the Pump, most are listedbelow. Please contact Medtronic MiniMed when in doubt if certainenvironmental 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 rotatingmagnetic 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 RadiationThe Medtronic MiniMed 2007D Implantable Insulin Pump System is notdesigned for use at elevations above 2,400 meters (8,000 feet). Use of the PumpSystem at higher elevations may result in insulin over delivery, which may causepersonal injury or death. Therefore, patients who live at elevations above 2,400meters (8,000 feet) should not use the Pump. Patients who use the Pump and whoplan to travel to an elevation above 2,400 meters (8,000 feet) should first havetheir Pump reservoir emptied of insulin, and they must self-administer insulin byother means for the duration of the trip and until their Pump reservoir is refilledagain.(This warning does not apply to travel on commercial aircraft because normalcabin 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 precautions84Physicians should instruct patients to avoid any sharp blows or pressure directlyat the Pump location. A direct hit by an object such as a baseball may damage thePump and/or injure the Pump pocket. Extreme pressure on the Pump may causethe sutures and the tissue pocket to be damaged. As a result, the Pump may movefrom its pocket and possibly dislodge from the Catheter.If the Pump has been damaged by such a blow, the patient should be instructed tocontact their physician. Physicians may order a pressure bandage or a reductionin the patient’s physical activity until the pump pocket reheals completely.• Exposure to Extreme Body TemperaturesExposure to elevated body temperatures in excess of 104°F (40°C) willcompromise the negative pressure reservoir safety feature of the MedtronicMiniMed 2007D Implantable Pump. Glucose levels should be monitored closelyif this occurs.SterilizationThe 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 USEthe packaged device.NOTE: Do Not Re-Sterilize the Implantable Insulin PumpNOTE: Do Not Re-Sterilize the Side Port CatheterNOTE: Do Not Re-Sterilize Components of the Refill Kit.The Pipette (MMT-4104), may be resterilized using autoclave, EtO or accordingto hospital procedures.The Template (MMT-4106) may be resterilized using steam autoclave or EtO perhospital procedure. This template is made from polycarbonate plastic and willhave a limited life in steam autoclave cycle. The template will not withstand dryheat autoclave cycles.

Warnings and precautions 85PrecautionsEmergencies and the use of conventional insulin suppliesPhysicians should advise patients who are implanted with the MedtronicMiniMed 2007D Implantable Insulin Pump System how to deal with emergencyconditions such as hyperglycemia and hypoglycemia. Patients should alwayscarry conventional insulin supplies with them, including insulin and a means toinject it, in the event of impaired insulin delivery by the Pump System. Deliveryof insulin can become impaired due to a failure of a Pump and/or PPC, or aCatheter occlusion. Replacement of the Pump, PPC or Catheter may be required.Physicians should review the Pump replacement and Catheter clearingprocedures in this Physicians Manual PPC reliability requirementsThe PPC is a sensitive electronic device, and can incur physical damage. If thePPC is dropped or receives an impact patients should be instructed toimmediately perform a SELF TEST to check the displays for proper operation. Ifthe PPC does not display correctly, a replacement PPC is required. Patientsshould initiate alternative diabetes management until a replacement PPC isreceived.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 eithersituation occurs, contact Medtronic MiniMed immediately and arrange for therepair or replacement of the PPC. If the PPC is accidentally splashed, sprayed orimmersed, remove excess moisture with a soft towel and then place the PPC in awarm place to thoroughly dry. When dry, perform a “SELF TEST.” If the PPCdoes not display correctly, call Medtronic MiniMed to replace the device. Maximum dosagesThe physician can program specific limitations to insulin Basal Rates and Bolusamounts, as well as total daily insulin usage. These limitations provide somecontrol of patients’ ability to program their insulin regimens, and to avoidoverdosing.

Warnings and precautions86Electrical and magnetic fieldsCommon electrical and magnetic fields that do not affect the Pump includemicrowave ovens, satellite receiving dishes, common household appliances,security devices found in department stores and airports, standard medical X-rays, cellular phone, and radiowaves.

87CHAPTER 8 Adverse reactionsAdverse reactionsIn clinical studies, adverse reactions associated with the Medtronic MiniMed2007D Implantable Pump included hypoglycemia, diabetic ketoacidosis,hyperglycemia, skin erosion, infection, abnormal healing, elevated anti-insulinantibodies, intestinal obstruction, post-operative discomfort and pain. PumpSystem malfunctions in order of frequency and seriousness include, insulinaggregation resulting in insulin under-delivery, Catheter occlusion or tissueovergrowth, premature depletion of the Pump battery, and failure of Pumpelectronics. Adverse events associated with the use of U-400 insulin aredescribed in the package insert accompanying the insulin medication.PreventionThe majority of adverse reactions in patients using the Medtronic MiniMed2007D Implantable Pump System can be prevented by teaching patientsdependable blood glucose monitoring. The patient plays a significant role indiagnosing and correcting Pump System performance problems. Should Pumpperformance change, the patient would be able to detect a change in bloodglucose 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. !WARNING

Adverse reactions88

89CHAPTER 9 System alarms and messagesThe Medtronic MiniMed 2007D Implantable Insulin Pump System is equippedwith various alarms and messages that ensure the correct function of the system.The Implantable Insulin Pump alarm system will “beep” when certain conditionsoccur. The beeps are designed to be audible through the skin and alert the patientthat the Pump needs attention. For severe alarm conditions the Pump will alarm 4tones 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 bypressing SEL then ACT. The following descriptions explain the alarm conditionsthe 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 thevibrate 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 everyminute 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 alternatingtones. 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 every30 minutes while the condition exists. If the PPC is set to “audible”, the PPC will beep 3 times every 30 minutes whilethe condition exists.Some alarms can be cleared by pressing SEL then ACT.

System alarms and messages90Pump alarmsAlarm feedbackThe Alarm Feedback function allows the user to verify the Pump and Pumpalarm 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 thefirst five Pump strokes:• Following a change in the delivery regimen, for example when completinga meal Bolus and then changing to a Basal Rate, or at the start of a bolus.• After the Alarm Feedback function is programmed “YES.” AlarmFeedback will stay on until programmed back to “NO.”Pump low batteryThe Implantable Insulin Pump battery is designed to last approximately ten yearsduring conditions of normal use (see Chapter 11 for Technical Specifications).Battery life may vary somewhat depending upon a user’s insulin deliveryrequirements. When battery energy becomes low, a voltage sensor in the Pumpwill trigger the Pump Low Battery Alarm. A Pump Low Battery Alarm indicatesthere 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 conventionalinsulin therapy should then be scheduled. Depleted pump batteryWhen there is no longer sufficient battery energy to power the Pump, the PumpLow Battery Alarm will cease and insulin delivery will stop. Alternate insulintherapy must be initiated.PPC Display Type of Alarm Pump AlarmPUMP LOW BATTERY 1 In 24 hours if no PPC communication

System alarms and messages 91System errorThe Implantable Insulin Pump has a sophisticated self-monitoring system thatperiodically checks for circuit faults. If a fault should occur in the Pump electron-ics, insulin delivery will stop. Conventional insulin therapy must be initiatedimmediately. Notify Medtronic MiniMed immediately. Pump self test failIf during a “SELF TEST” the Pump presents a malfunction, the insulin deliverywill stop. Clear the message by pressing SEL then ACT. Notify Medtronic Min-iMed immediately. PPC low batteryIf the PPC main battery (AA 1.5 volt alkaline) energy is low, the following alarmdisplay appears each time a new function is programmed:Clear this message by pressing SEL and then ACT. While the battery shouldhave sufficient energy for a few additional programming commands, the batteryshould be changed as soon as possible. For instructions on changing the battery,(see Chapter 3, Personal Pump Communicator).NOTE: If while programming the PPC, the screen goes blank, thePPC beeps six times and then the “CHECK PUMPSTATUS” message appears, the battery needs to bereplaced.

97CHAPTER 10 Troubleshooting Pump System under-deliveryPotential under-delivery of insulin by the Medtronic MiniMed 2007D Implant-able Insulin Pump System may result in an increase in daily programmed insulinusage, difficulty maintaining euglycemia, occasional hyperglycemia, and prob-lems calculating refill accuracy. This chapter describes how to diagnose potentialPump System problems that may cause insulin under-delivery, and offers poten-tial Pump and Catheter solutions to correct for under-delivery.Diagnostic proceduresWhen refill procedures reveal the possibility of a Pump System under-deliveryproblem, diagnostic procedures must be performed to verify if there is a problemwith either the Pump or Catheter. The Stroke Volume Measurement Proceduretests Pump function, while the Pressure Measurement Procedure tests Catheterpatency. These diagnostic procedures should be performed according to the stepsoutlined in Appendix G.Under-delivery caused by backflowBackflow results in the inverted flow of insulin through the Pump System. Back-flow is caused by insulin deposits that compromise valve integrity, and allow thenegative reservoir pressure (vacuum) to pull insulin back into the reservoir. Tocompensate for this under-delivery, the user can program appropriate increases intheir basal rates and bolus amounts.Backflow conditions are characterized by increases in daily programmed insulinusage, difficulty in maintaining euglycemia, increasingly negative refill accuracyand sometimes hyperglycemia. Confirm a backflow condition by performing theStroke Volume Measurement Procedure. Then rinse the Pump System withNaOH solution to dissolve insulin deposits, following the Pump Rinse Procedureoutlined in Appendix E.

Troubleshooting Pump System under-delivery98Under-delivery caused by catheter occlusionUnder-delivery caused by Catheter occlusion can occur either abruptly or gradu-ally. The insulin usage and clinical symptoms are identical to those of Pumpunder-delivery. Confirm a Catheter occlusion condition by performing a PressureMeasurement Procedure. Then perform the following procedures to clear theocclusion:• First, flush the Catheter by using the Side Port Catheter Flush Procedureoutlined 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 verificationsmust be performed.

All procedures should be performed using ASEPTIC TECHNIQUE.2. Air in the Pump System has been shown to be a significant contributingfactor to aggregation of insulin. Proper degassing of all solutions that enterthe Pump is essential. Read the insert in the refill kit packaging about thedegassing procedure.3. When using the refill kit, never release the syringe-locking ring while there isa vacuum within the refill syringe. The plunger of the syringe will snap backforcefully and may rupture the syringe and eject the contents.4. It is important that the syringe needle is perpendicular to the fill port toprevent 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 ofINSULIN. However, the INSULIN in the Pump fluid pathway and the sideport receptacle can be cleared by following the procedure to pull RINSEBUFFER through the side port. During a flush procedure to push out acatheter tip blockage, the 13 units in the distal catheter will be delivered tothe patient. The 13 units can be managed by programming continuous bolusamounts prior to the procedure, or with the use of oral or IV glucose asneeded during the procedure. Individual patient response to INSULIN bolusamounts must be considered.6. Patient blood glucose monitoring must be performed during, and up to onehour after the procedure. Oral and intravenous glucose should be availablefor glycemic management.

1107. After the flush procedure, at least 13 units of RINSE BUFFER will remain inthe distal portion of the catheter. Programmed bolus amounts to remove theRINSE BUFFER may be completed before the patient leaves the clinic. Aprescribed INSULIN basal rate should be programmed when the system isclear of RINSE BUFFER.8. Never push down on the plunger to fill the Pump. When the MedtronicMiniMed refill needle is properly seated in the fill port, the vacuum in thereservoir will draw the fluid from the syringe.9. Each step of the procedure will list the syringes and appropriate fluids neededfor that step. It is suggested that the syringes be prepared and labeled prior tothe start of the procedure.10. The Side Port Catheter is intended to be accessed only during the implantprocedure, the combined rinse/flush procedure, the catheter flush procedure,and for diagnostic procedures. The catheter is not intended to provide accessto the peritoneum for bolus injections of fluids or for withdrawal of bodyfluids.General procedures Before beginning any of the procedures, be sure you are familiar with the generaltechniques for locating the Pump fill port and the Side Port Catheter, accessingthe Pump inlet, venting the refill syringe, and preparing the syringes.

111Locating the pump fill port and the side portFigure 15: Template and placement1. Locate the Pump, then aseptically prep and drape the Pump area. Use topicalor local anesthetic if desired.2. To locate the Pump fill port, located in the center of the Pump, align thesterile template (MMT-4106) over the Pump by palpating the Pumpcircumference. Then insert an 18 gauge needle into the central Pump fill portas shown in Figure 15 above.3. To locate the side port, palpate around the circumference of the Pump. It ishelpful to grasp the side port between the thumb and index finger whenaligning the template.4. Using the template as a guide, insert the second 18 gauge needle into the sideport as shown. The side port can be accessed by inserting the guide needlejust inside the outer edge of the side port connection. This outer edge israised around the outer aspect of the side port, in order to help guide theneedle into the port.Template (MMT-4106)Placement on Skin with Guide Needles in Position

112Accessing the pump inlet(See Figure 16.) To enter the Pump fill port or the side port, make sure the refillsyringe 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 needleto enter the Pump fill port or the side port. The refill needle entry opens the inletvalve of the Pump fill port.After passing through the septum and seating in the valve, you can feel theincreased force, about 0.5 pounds, required to move the valve 0.5 millimeter toopen. Maintain this downward pressure in the pump fill port to ensure that theinlet valve remains open. In the case of the side port, a downward pressure is notrequired after the needle is completely inserted.Figure 16: Inlet valve

113Venting the Medtronic MiniMed refill syringe (optional)In order to fill the Pump, it may be necessary to vent the headspace in theMedtronic MiniMed refill syringe. Refill syringes do not have lubricant on thesyringe housing or on the plunger tip. Some syringes may be “sticky” and requirethe 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 syringeheadspace by pulling back firmly on the plunger until the second sealing ring onthe rubber cap passes beyond the vent hole as shown in Figure 17. Figure 17: Venting the refill syringeNOTE: Be sure that the plunger is retracted far enoughthat the vent hole is exposed. The syringe mustbe held with the needle facing down and usedwithin 10 minutes once it is vented. If this timelimit is exceeded, repeat the degassingprocedure and re-vent.

Enter the side port with syringe 5 - stopcock closed.4. Open the stopcock on syringe 5.

1355. Press SEL. When the PPC screen is flashing “PUMP SUSPEND” pressACT. The system is now in normal mode.6. Using the PPC, program and deliver a 4 unit bolus.7. Observe syringe 6. If the level of INSULIN approaches 2 mL, close thestopcock to prevent air from entering the Pump. Observe syringe 5. At least 1mL of INSULIN must pass into syringe 5 to be sure that all of the RINSEBUFFER is removed from the side port. If less than 1 ml enters, repeat thebolus from Step 7, some Pumps may require 3 successive boluses to obtain 1ml.8. Close both stopcocks. Remove syringe 6 from the Pump. Set the syringeaside to be weighed.9. With the stopcock closed, remove syringe 5 from the side port. It will have avacuum inside from the previous step. Enter the Pump fill port with syringe 5and open the stopcock and remove 2 ml. This will restore the negativepressure safety feature of the Pump.10. Close the stopcock, remove syringe 5 from the Pump, and set it aside to beweighed.11. Press SEL until the “SUSPEND PUMP” screen is displayed. Then PressACT.Remove guide needles and record refill amountAt this point, the 18 gauge guide needles should be removed, and the refillamount should be calculated and recorded.1. Remove the 18 gauge guide needles and discard them. Apply pressure to theinsertion sites.2. Weigh syringes 5 and 6 and record the combined weight on the Refill Form.Subtract the combined weight from the weight obtained in step 14. RemoveRinse Buffer and Fill with Insulin. The result is the new refill amount.3. Record the new and extracted refill amount in the PPC refill worksheet.Program new basal rateUsing the patient’s PPC, cancel the “SUSPEND” mode and allow the Pump toreturn to the patient’s original basal rate.

136Remove rinse buffer from catheterApproximately 13 units of RINSE BUFFER remain in the distal Side Port Cathe-ter. Depending on blood glucose values, program the appropriate bolus amount toremove the RINSE BUFFER from the Catheter. Release the patient when bloodglucose levels are stable.

137APPENDIX G Stroke volume measurement If under-delivery of insulin is noted during a refill procedure or suspected due toblood glucose control, it may be useful to verify the proper stroke volume of thePump by accessing the side port.In this procedure, a pipette is attached to a stopcock and refill needle. This systemis inserted into the side port. The insulin pulses in the pipette are measured to cal-culate the pump stroke volume.Supplies and solutions Prior to performing this procedure, assemble the necessary supplies and solutionsas outlined below:Supplies • Local anesthesia• Sharps container•PPC• Oral or IV glucose• Glucose monitoring equipment•Drapes• 5 ml or 3 ml syringe• One (1) sterile bag for PPC (intestinal or cassette bags work well)• One (1) Side port locating template, MMT-4106• One (1) sterile 100 microliter pipette, MMT-4104• Two (2) 18 gauge needles• One (1) MiniMed MMT-4102 refill needle. (Extra needles should beavailable to use as needed)

138• One (1) sterile stopcock - 3 waySolutions • One (1) 10 mL vial, Rinse Buffer Solution, MMT-2008Preparing for the procedure NOTE: Before beginning any refill, flush, stroke volumemeasurement, carefully read Appendix D, Precautionsand General Procedures, and keep this in mind as youperform each procedure.Record patient’s blood glucoseRecord the patient’s blood glucose value at the start of the procedure. Monitorblood glucose every 30 minutes, or as needed.Measuring stroke volume 1. In a sterile field before the procedure; prepare the apparatus. Prime thestopcock, pipette, and needle.2. Turn the stopcock as shown in Figure 18. Press on the syringe to obtain aliquid meniscus in the pipette.Figure 18: Stroke volume measurement setup

1393. Insert the needle into the side port.4. Turn the stopcock as shown in Figure 19. 5. Program a high rate bolus (approximately 20 units) and measure the strokevolume over 20 pulses in the pipette.6. Cancel the bolus at the end of the measurement.7. Turn the stopcock back to the position shown in Figure 19 to close. Removethe apparatus.Figure 19: Stroke volume measurement

140Record patient’s blood glucoseIt is likely that some insulin is pumped out of the Catheter and into the patient inthis procedure. Monitor the patient’s blood glucose and release the patient onlyafter blood glucose values are stable.
