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.At this time, the product has not been returned.If the product is returned, analysis will be performed, and this report would be updated should information be provided at that time.
