Event Description
|
It was reported that this device was suspected of exhibiting premature battery depletion behavior.During the previous follow-up visit, interrogation showed that the device had reached end of life (eol).Six months prior, the estimated battery longevity showed 1.5 years remaining.At that time, the device appeared to be fully functional, and had not entered safety mode.Subsequently, this device was explanted and replaced.The new device was programmed the same as the previous device, and lead parameters were stable.No additional adverse patient effects were reported.This device is expected for return.

Manufacturer Narrative
|
The returned device was inspected and analyzed upon receipt at our post market quality assurance laboratory.Visual examination of the device header and case noted no anomalies.Dimensional analysis of the header was completed.Each port measured as expected.Pacing and sensing functions were tested and the device was verified to operate as expected.Analysis did not identify any device characteristics that would have caused or contributed to the reported clinical observations.

Manufacturer Narrative

The returned device was thoroughly inspected and analyzed upon receipt at our post market quality assurance laboratory.Visual examination of the device header and case noted no anomalies.The device was then exposed to simulated heart load conditions, and the pacing, and sensing functions were tested.Impedance testing was completed, and all measurements were within normal limits.The device operated appropriately with no interruptions in therapy output at the returned programmed settings.A series of electrical tests was also performed, and again, normal device function was observed.Analysis did not identify any device characteristics that would have caused or contributed to the reported clinical observations.
