Additional Manufacturer Narrative
No further information concerning this report is available at this time.This investigation will be updated should further information be provided.
Event or Problem Description
It was reported that this device recorded a code 1003 indicative of battery voltage too low for the projected remaining capacity.Data analysis showed the battery appeared to be depleting more quickly than expected.Device replacement was recommended.This device remains in service.No adverse patient effects were reported.
Event or Problem Description
Additional information was received that this device was explanted after recording a code 1003.No additional adverse patient effects were reported.
Additional Manufacturer Narrative
This device was thoroughly inspected and analyzed upon receipt at our quality assurance laboratory.Review of the device memory indicated that a low voltage alert, code 1003, was recorded.The battery voltage was lower than expected.Using historical daily battery voltage measurement data, engineers determined that this device was demonstrating behavior consistent with a high current condition associated with a compromised low voltage capacitor connected to the device's battery.Low voltage capacitors are used in the device's high voltage charging operation in order to facilitate fast charge times.Malfunction of these capacitors resulted in a high current drain, which was depleting this device's battery faster than normal.
Additional Manufacturer Narrative
The product has been received for analysis.This report will be updated upon completion of analysis.
Event or Problem Description
This supplemental report is being filed to include additional device codes.
