MAUDE Adverse Event Report: BOSTON SCIENTIFIC CORPORATION ALTRUA 2 DR; IMPLANTABLE PULSE GENERATOR, PACEMAKER (NON-CRT)

Model Number	S702
Medical Device Problem Codes	Premature Discharge of Battery (1057); Battery Problem (2885)
Health Effect - Clinical Code	No Clinical Signs, Symptoms or Conditions (4582)
Date of Event	09/03/2021
Type of Reportable Event	Serious Injury
Event or Problem Description
It was reported that this device was suspected to be exhibiting premature battery depletion behavior.Between follow-up visits, a decrease of approximately 3.5 years in the battery's longevity was observed.The longevity is now showing approximately 3 months remaining, without any changes in device settings.A copy of device memory was saved and submitted to technical services (ts) for further battery analysis.A ts consultant confirmed that the power consumption has been increasing abnormally; therefore, confirming premature battery depletion.Due to this anomaly, device replacement was recommended.This device currently remains implanted and in service.No adverse patient effects were reported.

Additional Manufacturer Narrative
Upon receipt at our post market quality assurance laboratory, this device was thoroughly inspected and analyzed.A high current drain was detected, but the battery still supported full device function.Detailed analysis confirmed the identified high current drain was a result of compromised capacitors.This resulted in the observed premature battery depletion.It was determined that the capacitors were compromised due to the presence of excess hydrogen in the device case.Boston scientific issued a field safety notice in september 2018, which was expanded in june 2021, regarding a subset of devices in the accolade pacemaker family that has an elevated potential of exhibiting this behavior.This particular device is included in the hydrogen induced premature depletion advisory population.
