MAUDE Adverse Event Report: BOSTON SCIENTIFIC CORPORATION PUNCTUA ICD; IMPLANTABLE CARDIOVERTER DEFIBRILLATOR

Model Number	E050
Medical Device Problem Codes	Premature Discharge of Battery (1057); Noise, Audible (3273)
Health Effect - Clinical Code	No Clinical Signs, Symptoms or Conditions (4582)
Date of Event	01/14/2025
Type of Reportable Event	Serious Injury
Event or Problem Description
It was reported that this implantable cardioverter defibrillator (icd) recorded a code 1003 indicative of battery voltage too low for the projected remaining capacity and emitted a tone pattern with 1.5 years battery remaining.This icd was submitted for engineering analysis which resulted that this device exhibited a low voltage and the power consumption was increasing in gradual fashion.This appeared consistent with capacitor degradation due to hydrogen gas content in the sealed device atmosphere.Device replacement was recommended.This icd was explanted and replaced.No additional adverse patient effects were reported.

Additional Manufacturer Narrative
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 battery.Low voltage capacitors are used in the high voltage charging operation in order to facilitate fast charge times.The behavior of these capacitors resulted in a high current drain, which was depleting the device battery faster than normal.
