  1. Medtronic - LINQ II TM implantable cardiac monitor (Nov 2023)

A subset of devices with a manufacturing defect are susceptible to increased noise due to moisture affecting the electrode performance.

  1. Medtronic Device: CobaltTM XT/CobaltTM/CromeTM ICDs and CRT-Ds (May 2023)

Reduced or no-energy output during HV therapy in ICDs/CRT-Ds manufactured with a specific (glassed) feedthrough, including currently available ICDs and CRT-Ds.

  1. Medtronic Cobalt XTTM CobaltTM and CromeTM ICDs CRT-Ds (June 2022)

Potential for shocks to be ~79% of the programmed energy as a result of a safety feature, Short Circuit Protection, designed to truncate delivered energy to protect the device when unexpected current is detected during HV therapy.

  1. Medtronic CobaltTM and CromeTM ICDs and CRT-Ds (May 2022)

May encounter a persistent "session-active"flag following the use of inductive telemetry, typically with CareLink Express. This will result in temporary suspension of some features until the flag is cleared.

  1. Medtronic CobaltTM and CromeTM ICDs and CRTDs (Oct 2021)

Rarely SmartStync interrogation sessions, or CareLink network transmissions may fail for Cobalt or Crome devices when the current session diagnostic data includes any VT/VF episode type with multiple therapy sequences and three or more data recording suspensions. SmartSync will display "Unexpected error occured", and the app. requires restarting. Within CareLink, the current transmission processing may fail, and the information will not be viewable.

  1. Medtronic: Reveal LINQTM with TruRhythmTM ICMs (June 2021)

After partial electrical reset, usually after DCCV or electrocautery, Brady & Pause events appear to be "ON", but are no longer able to detect/report.
