FDA recalls for this device

Class II

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.

Class II

Mar 10, 2022 · Open, Classified

Bluetooth malfunction impacting Gallant devices post-implant. The failure causes the device to enter an inductive-only telemetry mode with a loss of Bluetooth communication. The Bluetooth malfunction results in the inability to remotely monitor these devices and resulted in reduced battery longevity.
