   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.

2. Jul 31, 2024Class IOpen, Classified

   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.

3. Sep 20, 2022Class IIOpen, Classified

   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.
