Event or Problem Description
It was reported that during explant procedure, the physician was using electrocautery and this pacemaker exhibited pacing inhibition for more than two seconds.Technical services (ts) discussed it could be the device sensed extra energy and reacted to prevent energy from being delivered in an unintended location.This pacemaker was successfully explanted due to normal battery depletion and replaced.No adverse patient effects were reported.
Additional 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.Dimensional analysis of the header was completed.Each port measured as expected.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.
