Automated Insulin Dosing Device System, Single Hormonal Control（OZP）

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.

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.

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.

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.

Due to battery cap deterioration, this may potentially result in an incomplete battery circuit (similar to when battery cap is not attached) and a loss of power/functionality of the insulin infusion pumps.

New or replacement insulin pumps are not pre-programmed with basal rates or other verified settings (bolus wizard settings, sensor settings, etc.), which must be set up and saved on pumps prior to use. Patients who do not realize this will receive no basal insulin, which can lead to insulin under-delivery. Insulin under-delivery can cause severe hyperglycemia, which may lead to diabetic ketoacidosis. Current device labeling does not clearly identify that these insulin pumps are capable of functioning with the default basal setting of 0.0 units/hr for all 24 hours and that no error message will appear if the default basal setting remains active. Furthermore, the labeling for the affected devices does not highlight that saving the basal settings requires multiple steps and failure to complete all steps will not save the new basal settings, nor that the steps required to set and save a basal profile and other parameters which are used as part of the bolus calculator function are different.

Due to a software design issue, under certain conditions, a software fault is detected when a large bolus delivery at quick bolus speed completes. if the user is not aware of the amount of active insulin and delivers an additional bolus, there is a risk of insulin over delivery.

Missing solder battery connection, which could interrupt power of insulin pump.

There have been reported incidents of a loose reservoir that can no longer be locked into the pump. The reservoir can become loose due to a broken or missing retainer ring that prevents a proper lock. If the reservoir is not properly locked into the pump, it could lead to over or under delivery of insulin, which could then result in hypoglycemia or hyperglycemia.
