MAUDE Adverse Event Report: BOSTON SCIENTIFIC CORPORATION PUNCTUA CRT-D; IMPLANTABLE PULSE GENERATOR, PACEMAKER (NON-CRT)

Model Number	N051
Medical Device Problem Codes	Premature Discharge of Battery (1057); Device Displays Incorrect Message (2591)
Health Effect - Clinical Code	No Known Impact Or Consequence To Patient (2692)
Date of Event	08/16/2019
Type of Reportable Event	Serious Injury
Event or Problem Description
It was reported that this cardiac resynchronization therapy defibrillator (crt-d) recorded a code 1003 indicative of battery voltage too low for the projected remaining capacity.No adverse patient effects were reported.This product remains in service.This report will be updated, should additional information be received.
Additional Manufacturer Narrative
The event date was updated, after device evaluation was completed.The returned implantable cardioverter defibrillator (icd) was analyzed and a review of the device memory confirmed that a low voltage alert, code 1003, was recorded.The battery voltage was lower than expected, but still supported full device function.Using historical daily battery voltage measurement data, engineers determined that this device was demonstrating behavior consistent with a high current condition associated with a compromised low voltage capacitor connected to the device's battery.Low voltage capacitors are used in the device's high voltage charging operation in order to facilitate fast charge times.Malfunction of these capacitors resulted in a high current drain, which was depleting this device's battery faster than normal.Boston scientific has issued an advisory communication regarding an older subset of cognis/teligen devices that is more susceptible to this anomaly.Specifically, the performance of a low voltage capacitor may be compromised over time, causing an increased current drain that can lead to premature battery depletion.This device was not included in the advisory population.
Event or Problem Description
Additional information was reported indicating that this crt-d was removed and replaced.The icd was returned and a device evaluation was completed.
