  MiniMed 670G Insulin Pump (MMT-1760, MMT-1761, MMT-1762, MMT-1780, MMT-1781, MMT-1782)

  All Medtronic MiniMed infusion pumps (Paradigm series, 600 series, and BLE 700 series) were found to be affected by unintended over- and under-delivery of insulin when the pump is elevated or lowered relative to the infusion site, respectively, because of changes in gravitational force impacting hydrostatic and hydrodynamic pressures. Insulin over-delivery, which can occur when the pump is elevated relative to the infusion site, can result in severe hypoglycemia, altered mental status, seizure, coma, or death. An under-delivery of insulin, which can occur at lowered pump height conditions relative to the infusion site, can result in severe hyperglycemia, dehydration, diabetic ketoacidosis, or death.

  MiniMed 780G Insulin Pump Catalog Numbers: MMT-1884 MMT-1886 With Software Version 6.60 The MiniMed 780G insulin pump is indicated for use by patients age 7-80 years with Type 1 diabetes, whose total daily dose of insulin is 8 units per day or more. The MiniMed 780G system is intended for continuous delivery of basal insulin at selectable rates, and the administration of insulin boluses at selectable amounts for the management of type 1 diabetes mellitus in persons seven years of age and older requiring insulin. The system is also intended to continuously monitor glucose values in the fluid under the skin. The MiniMed 780G system includes SmartGuard technology, which can be programmed to automatically adjust insulin delivery based on continuous glucose monitoring (CGM) sensor glucose values and can suspend delivery of insulin when the SG value falls below or is predicted to fall below predefined threshold values.

  A software timing and processor communication issue in MiniMed" 780G software version 6.60 may trigger Pump Error 43 and/or Pump Error 41, resulting in suspension of insulin delivery.

  MiniMed insulin pump, REF: 670G (MMT-1760, MMT-1761, MMT-1762, MMT-1780, MMT-1781, MMT-1782)

  All Medtronic MiniMed pumps (Paradigm series, Minimed 530G, 6XX series, and 7XX series) were found to have the potential for abnormal insulin delivery due to changes in air pressure, which can be found during airplane take-off or landing. An unexpected additional dose of insulin, which can occur during take-off, can result in severe hypoglycemia, altered mental status, seizure, coma, or death. An unexpected under-delivery of insulin, which can occur during landing, can result in severe hyperglycemia, dehydration, diabetic ketoacidosis, or death.

  Insulin pumps that have been dropped, bumped, or experienced physical impact may have damage to internal electrical components, which may cause reduced pump battery life. Since the defect reduces the battery life overall, it shortens the time between low battery alarms and increases the frequency with which the user must insert a new battery. Further, the defect may also deliver the low battery alarm when there is significantly less time before the battery completely runs out, from the expected up to 10-hour buffer the low alert is supposed to signal, leading to device powering down and stopping insulin delivery unexpectedly. Per the firm, a subset of pumps with the defect showed the low alert alarm was delivered ~2.5 hours before the device shut off, however, patient reports indicate the time could be even shorter. Replacing the battery will not resolve this issue and the short battery life and the truncated low battery alert lead time will continue to occur. Early battery depletion could result in power loss and insulin delivery could be interrupted, resulting in under delivery of insulin potentially leading to hyperglycemia and/or DKA.

  Guardian 4 Glucose Sensor, REF: MMT-7040A, MMT-7040C1, MMT-7040C2, MMT-7040C3, MMT-7040D1, MMT-7040D2, MMT-7040MA, MMT-7040QC1, MMT-7040QC2, MMT-7040QC3

  Some sensors may have a glucose oxidase (GOX) layer thickness outside of specification (5.5 to 9.2 m). A non-conforming GOX layer thickness could impact sensor function (sensor glucose value) or loss of sensor function due to the sensor layer being too thin. The potential impact resulting from this issue ranges from user inconvenience to over/under delivery of insulin, possibly resulting in hyperglycemia or hypoglycemia, if the sensor glucose values are affected. The issue was identified by the manufacturing team during the execution of Filmetrics Measurement for a Guardian Sensor lot.

  Medtronic identified a cybersecurity vulnerability in the MiniMed 600 series Insulin Pump Systems associated with the communication protocol that could allow unauthorized access to the pump system. This unauthorized access could be used to deliver too much or too little insulin through delivery of an unintended insulin bolus or because insulin delivery is slowed or stopped, which could lead to hypoglycemia or hyperglycemia. The Remote Bolus feature on insulin pumps should be turned off to prevent the unauthorized access.
