  MiniMed 630G Insulin Pump (MMT-1714, MMT-1715, MMT-1754, MMT-1755)

  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 insulin pump, REF: 630G (MMT-1714, MMT-1715, MMT-1754, MMT-1755)

  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.

  MiniMed 630G Insulin Pump, REF: MMT-1515, MMT-1714, MMT-1715, MMT-1754, MMT-1755; MiniMed 700G Insulin Pump, REF: MMT-1800, MMT-1801, MMT-1805, MMT-1850, MMT-1851

  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.

• 2020-02-07Open, ClassifiedDevice Design

  Medtronic MiniMed 630G System with SmartGuard, Ref/Model # MMT-1515, MMT-1715, MMT-1714, MMT-1754, and MMT-1755 *US and Canada Version Only

  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.

• Open, ClassifiedNonconforming Material/Component

  MiniMed 630G with SmartGuard, insulin pump, Ref/Model # MMT-1754K, MMT-1714K, MMT-1755K - Product Usage: intended for continuous delivery of basal insulin (at user selectable rates) and administration of insulin boluses (in user selectable amounts) for the management of diabetes mellitus in persons, fourteen years of age and older, requiring insulin.

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

• TerminatedSoftware Manufacturing/Software Deployment

  Medtronic CareLink iPro Therapy Management Software, MMT-7340 The CareLink iPro Therapy Management Software (model, MMT-7340) is intended to be used by a healthcare professional (HCP) with the iPro2 CGM System and provides upload support for the iPro2 Recorder. The CareLink iPro software is used to upload glucose sensor data stored on a recording device, capture BG meter readings through manual entry or wired-upload, retrospectively calibrate sensor data, and provide retrospective reports of continuous glucose information. The reports generated by the CareLink iPro software are intended for use by healthcare professionals to assist with diabetes clinical assessment, patient education, and therapy optimization.

  Due to a time conversion error, data uploaded from the iPro(TM)2 recorder to the CareLink iPro software using the new CareLink iPro Uploader feature may result in incorrect reports. This pertains only to reports generated between September 23, 2017 and September 27, 2017 that used the new CareLink iPro Uploader feature.

  Reports of occurrences in which insulin pumps with version 4.10 software have failed to make expected audio sounds during alerts, alarms or sirens. This could cause a user to miss system notifications, alarms or sirens associated with how the pump is working, and with high and low glucose alerts.
