Medtronic

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.

Three software defects (Pump Error 53, BG check, and Critical Pump Error (Open Book Image)) that occurred as a result of software updates (versions 6.60, 6.61, and 6.62), which could result in a risk of hypoglycemia or hyperglycemia due to inaccuracies in insulin delivery (either under-delivery, over-delivery, or cessation of delivery).

During the manufacturing, Medtronic personnel identified an assembly issue where the tubing was incorrectly positioned. The short tube was attached to the bottom of the canister, and the long tube was attached to the top, contrary to the intended design.

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.

Stents may be impacted by a Nitinol anomaly which causes a reduced stent diameter when deployed and corresponding reduced radial force. Issue may result in stent migration.

Software issue where a Device Reset message displayed on the app was unable to be cleared. In rare cases, this resulted in an inability to resume therapy, and the patient experienced a recurrence of underlying pain symptoms. Resolution would require surgical replacement of the INS.

When app is uninstalled and reinstalled, insulin pen software issue causes Choose Notification Style Screen to not show during setup so users can't choose to allow notifications to override phone settings when on mute/Do Not Disturb, and previously set up override permission is deleted, so audible and vibratory notifications not received, which may lead to delayed insulin therapy, hyperglycemia.

There is a potential for delayed time to high-voltage (HV) therapy should a rare sequence of events occur.

Software error causing incorrect data to be displayed on the 24-hour Sensor Glucose Overview Graph, any potential therapy decisions were made based on the incorrect data displayed on the 24-hour sensor glucose overview graph may lead to hypoglycemia or hyperglycemia.

Expandable interbody system cage may loose height or collapse (loss of lordosis), which could result in migration, subsidence and/or neurological injury. Therefore, surgical technique and instructions for use will be updated to mitigate risk of loss of lordosis to occur.

Medtronic personnel observed trace amounts of dry blood on the external carton label and Instructions for Use (IFU) in five boxes of one lot of ACT Cartridges.

As of August 6, 2025, Medtronic has received eleven reports of VitalFlow Consoles displaying an E70 error code during normal operation. When this occurs, the touch screen may become temporarily unresponsive and go blank for up to two minutes before recovering to full functionality. Importantly, the console continues to maintain set pump speed and function throughout.

Medtronic identified an Affinity NT Oxygenator unit with decreased CO2 gas transfer rates that did not meet performance requirements.

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.

There was a label mix-up between two model numbers resulting in the incorrect guidewire being contained in the kits for both model numbers.
