INTRODUCTION The Medtronic MiniMed Implantable Pump System is a sophisticated combination of technologies developed to address the requirements of continuous intraperitoneal insulin delivery for patients with Insulin Dependent Diabetes Mellitus (IDDM). The system is comprised of: Implantable Pump, Side Port Catheter, Personal Pump Communicator, and accessory syringe, needle, template, and pipette. The pump and catheter are designed for implantation. The Personal Pump Communicator is designed to provide the patient a variety of insulin delivery options. The accessory items are specifically designed to facilitate refill of the implanted pump and pump functions. INDICATIONS FOR USE The Medtronic MiniMed Personal Pump Communicator is intended to be used with the Medtronic MiniMed Implantable Pump. Specific indications for use of the Implantable Pump System are provided in the Implantable Pump Package Insert. CONTRAINDICATIONS The Medtronic MiniMed Implantable 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 the treating physician and other healthcare providers. • Reside at or travel (other than by commercial aircraft) at elevations above 8000 feet. • Have other medical or mental conditions which may place the patient at risk. • Are unwilling or unable to return for routine insulin refill (approx. 2-3 months) according to dosage. • Present current or history of sensitivity to titanium alloy or silicone materials used in the manufacture of system implanted components. PRECAUTIONS Patients should always maintain conventional insulin supplies in the event of pump and or Personal Pump Communicator (PPC) failure. Delivery of insulin can become impaired due to pump failure or catheter occlusion. In the event of impaired insulin delivery, replacement of the pump or catheter may be required. Physicians should review Physicians Manual for full description of Pump replacement procedure and catheter clearing procedures. The Medtronic MiniMed Pump and Catheter Implants should NOT be used if damaged prior to or during implantation procedures. The pump should not be placed in contact with other metal implants. WARNINGS Physicians should be completely familiar with the function of the pump, catheter, and personal pump communicator prior to use of this device. Patients should be provided a complete copy of the Patient Manual and have demonstrated the ability to program the Personal Pump Communicator (PPC), recognize and respond to safety alarms, and care of the device prior to discharge. The Medtronic MiniMed Implantable Pump System should not be exposed to therapeutic ultrasound. Exposure to ultrasound therapy may cause damage to the pump that may not be apparent. Only special U400 insulins may be used in the Medtronic MiniMed Implantable Pump System. 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 system may prevent effective use of that and other components. POSSIBLE ADVERSE EFFECTS The Medtronic MiniMed Implantable Pump System has undergone an extensive clinical evaluation. Evaluation of the system spanned a period of ten years and involved over 600 subjects in the United States and Europe. Though over delivery of insulin did not occur during the ten year evaluation period, there is a potential for such 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 devise, but are important considerations particularly in the treatment of people with diabetes. The general surgical risks as well as operative site cosmetic risks should be explained to the patient prior to surgery.

85 Fill the Pump with insulin 1.Remove another refill syringe (IN2) from a refill kit package. 2.Firmly attach the two-way stopcock to the refill syringe and attach an 18 gauge needle to the stopcock. Label the syringe IN2. 3.Draw 20 mL of INSULIN (two vials) into the IN2 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 INSU- LIN. 8.Point the syringe tip upward and slowly open the stopcock to vent the syringe. 9.Release the locking ring on the refill syringe. 10.Expel the air in the syringe and carefully observe it to ensure no air bubbles remain in the syringe. If air bubbles are noted, repeat steps 5 - 10. 11.Fill the hub of the refill needle with INSULIN and attach it to the stopcock. 12.Prime the needle and close the stopcock. 13.Place a sterile beaker or sterile barrier towel on the scale and tare it (position balance at 0.) 14.Weigh the refill syringe and record the weight on the Implant Work- sheet. Dmp9196021-011_c.book Page 85 Wednesday, April 3, 2002 5:04 PM 86 15.Press the refill syringe into the Pump fill port, open the stopcock and allow the Pump vacuum to draw INSULIN into the reservoir until the fluid level stops moving. Close the stopcock. 16.Remove the IN2 syringe and prepare for aspiration without expelling any fluid. 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. 17.Reenter the Pump fill port with the stopcock closed. 18.Open the stopcock and withdraw 2 mL in order to activate the nega- tive pressure safety feature of the Pump. Close the stopcock and remove the syringe. 19.Weigh the IN2 syringe to calculate the Pump refill amount. Subtract the weight after the fill and 2 mL withdrawal from the weight before the fill and record the difference on the Implant Worksheet. 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. Reen- ter 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 Dmp9196021-011_c.book Page 86 Wednesday, April 3, 2002 5:04 PM 87 time the priming bolus was initiated on the implant worksheet. If you have removed the plastic tubing placed on the Pump outlet, DO NOT TRY TO REPLACE THE TUBING BACK ON THE PUMP OUTLET. You can displace or damage the “O” ring placed around the outlet. To measure the stroke volume, you 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. ! WARNING Dmp9196021-011_c.book Page 87 Wednesday, April 3, 2002 5:04 PM 88 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. !

117 CHAPTER 9System Alarms and Messages The Medtronic MiniMed 2007C Implantable Insulin Pump System is equipped with various alarms and messages that ensure the correct func- tion 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 con- ditions the Pump will alarm 4 tones each minute for 10 minutes then, 4 double tones each minute for 10 minutes and repeat the pattern. Upon hearing the alarm, the patient must communicate with the PPC, to deter- mine 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 chapter 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 minutes. 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. Dmp9196021-011_c.book Page 117 Wednesday, April 3, 2002 5:06 PM System Alarms and Messages 118 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. 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 Feed- back to measure the time intervals between Pump strokes to verify accu- rate 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, Technical Specifications). Battery life may vary somewhat depending upon a user’s insulin delivery requirements. When battery energy becomes low, a volt- age 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. Dmp9196021-011_c.book Page 118 Wednesday, April 3, 2002 5:06 PM Pump alarms 119 The Pump Low Battery alarm can be cleared and the Pump will continue to operate normally. However, users should be instructed to report the alarm immediately 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. Alter- nate insulin therapy must be initiated. System error The Implantable Insulin Pump has a sophisticated self-monitoring system that periodically checks for circuit faults. If a fault should occur in the Pump electronics, insulin delivery will stop. Conventional insulin therapy must be initiated immediately. Using the PPC Supervisor Mode, the phy- sician should use the “DOWNLOAD SOFTWARE” feature to reprogram the Pump from software in the PPC memory. Notify MiniMed immedi- ately.

Clear the message by pressing SEL then ACT. Notify MiniMed immediately. PPC alarms The PPC offers a choice of two alarms, audible and vibrate. In addition, a screen message appears indicating the type of alarm condition that occurred. PPC low battery If the PPC main battery (AA 1.5 volt alkaline) energy is low, the follow- ing alarm display appears each time a new function is programmed: Clear this message by pressing SEL and then ACT. While the battery should have sufficient energy for a few additional programming com- mands, the battery should be changed as soon as possible. For instruc- tions on changing the battery, (see Chapter 3, Personal Pump Communicator). If “VIBRATOR” is selected, the PPC bat- tery should last about six weeks during nor- mal use conditions. If the PPC determines that the vibrator is causing a low battery condition, it will automatically change the A l a r m M o d e t o “ L O W V O L U M E ” i n order to extend battery life.

145 APPENDIX DPrecautions 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 contribut- ing factor to aggregation of insulin. Proper degassing of all solutions that enter the Pump is essential. Read the insert in the syringe packag- ing 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 con- tain 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 Dmp9196021-011_c.book Page 145 Wednesday, April 3, 2002 5:07 PM 146 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 cautions bolus amounts prior to the proce- dure, or with the use of oral or IV glucose as needed during the proce- dure. 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. 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 MiniMed refill needle is properly seated in the fill port, the vacuum in the reser- voir 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 Cath- eter, accessing the Pump inlet, venting the refill syringe, and preparing the syringes. Dmp9196021-011_c.book Page 146 Wednesday, April 3, 2002 5:07 PM Special note and precautions 147 Locating the pump fill port and the side port Figure 16: Template and Placement on Skin with Guide Needles in Position 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 below: 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. Dmp9196021-011_c.book Page 147 Wednesday, April 3, 2002 5:07 PM 148 This outer edge is raised around the outer aspect of the side port, in order to help guide the needle into the port. Accessing the pump inlet To enter the Pump fill port or the side port, make sure the refill syringe stopcock is closed, then pass the MiniMed refill needle (MMT- 4102) through the 18 gauge guide needle. Pull back slightly (approximately 2 mm) on the guide needle to allow the 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 mil- limeter 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 17: Inlet Valve Dmp9196021-011_c.book Page 148 Wednesday, April 3, 2002 5:07 PM Special note and precautions 149 Venting the Minimed refill syringe (optional) In order to fill the Pump, it may be necessary to vent the headspace in the 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 overcome 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 18.
