    Additional Manufacturer Narrative · 1

    (B)(4). UPON RECEIPT AT OUR QUALITY ASSURANCE LABORATORY, THIS DEVICE WAS THOROUGHLY INSPECTED AND ANALYZED. REVIEW OF THE DEVICE MEMORY CONFIRMED LOW VOLTAGE ALERTS (CODE 1003) HAD BEEN RECORDED. INITIAL AUTOMATED TESTING VERIFIED BASIC SENSING, PACING AND SHOCKING FUNCTIONS OF THE DEVICE. USING HISTORICAL DAILY BATTERY VOLTAGE MEASUREMENT DATA, ENGINEERS DETERMINED THAT THIS DEVICE WAS DEMONSTRATING BEHAVIOR CONSISTENT WITH A HIGH CURRENT CONDITION ASSOCIATED WITH COMPROMISED LOW VOLTAGE (BYPASS) CAPACITORS 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. ON (B)(4), 2013, BOSTON SCIENTIFIC DISTRIBUTED A LETTER TO PHYSICIANS CONCERNING THIS ISSUE. THIS LETTER INFORMED PHYSICIANS THAT, IN A SUBSET OF DEVICES, THE PERFORMANCE OF A LOW VOLTAGE CAPACITOR MAY BE COMPROMISED OVER TIME, CAUSING INCREASED CURRENT DRAIN THAT CAN LEAD TO PREMATURE BATTERY DEPLETION. THIS DEVICE IS NOT A PART OF THE IDENTIFIED POPULATION

    (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 NOT INCLUDED IN THE AUGUST 29, 2013 ADVISORY POPULATION, BUT WAS ADDED TO THE EXPANDED POPULATION ON SEPTEMBER 17, 2014.

    BOSTON SCIENTIFIC RECEIVED INFORMATION THAT THIS DEVICE RECORDED A CODE 1003 INDICATIVE OF BATTERY VOLTAGE TOO LOW FOR THE PROJECTED REMAINING CAPACITY. DATA ANALYSIS SHOWED THE BATTERY APPEARS TO BE DEPLETING MORE QUICKLY THAN EXPECTED. DEVICE REPLACEMENT WAS RECOMMENDED. THIS DEVICE WAS EXPLANTED AND REPLACED WITH A NON-BOSTON SCIENTIFIC DEVICE.
