The reported events of inability to interrogate and no pacing output were confirmed.As received, the device had no telemetry communication and no output.Visual inspection of the header attachment area detected a bonding anomaly.A device hermeticity breach was observed, consistent with feedthrough damage as a result of fluid intrusion between the header and case, and subsequent fluid ingress to the internal electronics.The device was cut open to enable further testing and the battery was found depleted.Hybrid circuitry was tested indicating high current drain, consistent with moisture damage, depleting the battery and resulting in the reported events.A manufacturing anomaly may have occurred, which resulted in the header bonding anomaly.As a result of this finding, abbott is performing further investigation.
