Detection
Regulatory
Aug 16, 2023 · Open, Classified
Due to Bluetooth malfunction on a subset of Implantable Cardioverter Defibrillator (ICD) and Cardia Resynchronization Therapy Defibrillator *CRT-D) devices that were manufactured prior to April 2022 as a result of crystal component issue within the Bluetooth Low Energy (BLE) circuit. This results in the device entering an inductive telemetry only mode with loss of Bluetooth communication. In some instances, thought BLE communication is unavailable, the circuit may remain in a state which draws excessive power affecting battery longevity.
Mar 10, 2022 · Open, Classified
Due to a programmer software anomaly under very specific circumstance when executing a pacing capture Decrement Test in-clinic on implantable cardioverter and cardiac resynchronization therapy defibrillator devices, the programmer may continue to execute the Decrement Test instead of terminating the test and restoring the permanent programmed pacing parameters.
