Event Description
|
It was reported that the patient with this implantable cardioverter defibrillator (icd) experienced cardiac arrest.The patient needed to be externally resuscitated and was treated in a hospital setting and hospitalized in the icu.It was noted this device was unable to be interrogated.No magnet response was found.Different programmers were used, however, interrogation of the device was not successful.A device system revision is scheduled in the near future.No additional adverse patient effects were reported.At this time, this device system remains in service.

Manufacturer Narrative
|
Upon receipt at our post market quality assurance laboratory, a thorough evaluation of the product was performed.Review of device memory confirmed the presence of a higher than normal current drain condition.Electrical testing and analysis were then conducted, which isolated the high current to an anomaly in an oxide layer within a custom integrated circuit component.This anomaly caused a high current drain, which over time resulted in the reported clinical observations.
