    Additional Manufacturer Narrative · 1

    (B)(4). AS NO FURTHER INFORMATION CONCERNING THIS REPORT IS EXPECTED, OUR INVESTIGATION IS COMPLETE. THIS INVESTIGATION WILL BE UPDATED SHOULD FURTHER INFORMATION BE PROVIDED.

    Additional Manufacturer Narrative · 1

    (B)(4). BOSTON SCIENTIFIC HAS ISSUED AN ADVISORY COMMUNICATION REGARDING AN OLDER SUBSET OF COGNIS/TELIGEN DEVICES THAT IS MORE SUSCEPTIBLE TO THIS ANOMALY. SPECIFICALLY, THE PERFORMANCE OF A LOW VOLTAGE CAPACITOR MAY BE COMPROMISED OVER TIME, CAUSING AN INCREASED CURRENT DRAIN THAT CAN LEAD TO PREMATURE BATTERY DEPLETION. THIS PARTICULAR DEVICE WAS INCLUDED IN THE ADVISORY POPULATION.

    Additional Manufacturer Narrative · 1

    (B)(4). 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, BUT STILL SUPPORTED FULL DEVICE FUNCTION. A SERIES OF AUTOMATED ELECTRICAL/FUNCTIONAL TESTS WERE CONDUCTED AND NO ISSUES WITH DEVICE PERFORMANCE WERE OBSERVED; BASIC SENSING, PACING AND SHOCKING FUNCTIONS OF THE DEVICE WERE VERIFIED. 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. BOSTON SCIENTIFIC HAS ISSUED AN ADVISORY COMMUNICATION REGARDING AN OLDER SUBSET OF COGNIS/TELIGEN DEVICES THAT IS MORE SUSCEPTIBLE TO THIS ANOMALY. SPECIFICALLY, THE PERFORMANCE OF A LOW VOLTAGE CAPACITOR MAY BE COMPROMISED OVER TIME, CAUSING AN INCREASED CURRENT DRAIN THAT CAN LEAD TO PREMATURE BATTERY DEPLETION. THIS PARTICULAR DEVICE WAS INCLUDED IN THE ADVISORY POPULATION.

    Description of Event or Problem · 1

    AS PART OF AN ANALYSIS TO REVIEW THE SAFETY ARCHITECTURE LOW VOLTAGE ALERT (CODE 1003), BATTERY VOLTAGE DATA WAS PULLED FROM THE REMOTE PATIENT MONITORING SYSTEM. DURING OUR ANALYSIS, THIS DEVICE WAS IDENTIFIED AS DEMONSTRATING EVIDENCE OF PREMATURE BATTERY DEPLETION THAT COULD POTENTIALLY LEAD TO COMPROMISED THERAPY IF NOT ADDRESSED IN A TIMELY MANNER. BOSTON SCIENTIFIC TECHNICAL SERVICES PROACTIVELY REACHED OUT TO THE FIELD REPRESENTATIVE TO NOTIFY THEM OF THIS FINDING AND RECOMMEND DEVICE REPLACEMENT. THE DEVICE WAS EXPLANTED AND REPLACED. THERE WERE NO ADDITIONAL ADVERSE PATIENT EFFECTS REPORTED
