  InPen App, CFN: MMT-8060 (iOS Users) and MMT-8061 (Android Users)

  Medtronic MiniMed, Inc. is recalling InPen App for iOS and Android users due to software design errors that could lead to a missed short-acting insulin dose reminder and a recommendation to correct a high glucose value. It does not impact insulin delivery, long-acting insulin dose reminders, or CGM alerts, and users can still use the pen itself to calculate a dose, deliver insulin, record the dose date/time, and view CGM data. This issue was identified during internal testing before release in the US but after release to OUS customers, no complaints or MDRs related to this recall have been reported. Use of the affected device may result hyperglycemia by failing to alert the user and delay treatment of diabetes.

  Accu-Chek Connect Diabetes Management App

  iOS and Android: Under certain conditions the affected app versions may disregard historical bolus data potentially leading to an incorrect bolus insulin recommendation being provided to the user. iOS only: Pairing and using multiple meters with the Accu-Chek Connect app can under rare circumstances cause the bolus advisor to fail to offer a correction bolus recommendation within the eligible time window following a blood glucose measurement (10 15 minutes). Depending on the individual metabolic situation potentially incorrect bolus advice could lead to serious health consequences such as hypoglycemia. Both software issues may also cause the amount of active insulin displayed during the bolus calculation process to be incorrect and should not be used to manually calculate a bolus.
