    A SUPPLEMENTAL REPORT IS BEING SUBMITTED FOR DEVICE EVALUATION. PRODUCT EVENT SUMMARY: THE BATTERY ((B)(6)) WAS RETURNED FOR EVALUATION. VARIOUS ANALYSES WERE CONDUCTED AND REVIEWED IN ORDER TO EVALUATE THE PERFORMANCE OF THE DEVICE IN RELATION TO THE REPORTED EVENT. FAILURE ANALYSIS OF THE RETURNED DEVICE REVEALED THAT THE UNIT PASSED VISUAL INSPECTION. FUNCTIONAL TESTING REVEALED THAT THE BATTERY WAS UNABLE TO CHARGE OR PROVIDE POWER DUE TO AN ENABLED ZERO-VOLT CHARGE (ZVCHG) FIELD-EFFECT TRANSISTOR (FET). THE GAS GAUGE IS NOT PROGRAMMED TO USE THE ZVCHG FET, WHICH INDICATES THAT THE BATTERY UNINTENTIONALLY ENABLED THE FET. THE ZVCHG FET DISABLES THE CHARGE AND DISCHARGE FETS, RENDERING THE BATTERY INOPERABLE. IF THE BATTERY WITH THE ZVCHG FET ENABLED REMAINS CONNECTED TO THE BATTERY CHARGER, THE BATTERY CHARGER LED STATUS INDICATOR WILL FLASH RED AFTER 8 HOURS DUE TO A CHARGE TIME-OUT. AS A RESULT, THE REPORTED EVENT WAS CONFIRMED. THE MOST LIKELY ROOT CAUSE OF THE REPORTED EVENT CAN BE ATTRIBUTED TO THE UNINTENTIONAL ENABLING OF THE BATTERY'S ZVCHG FET. AN INTERNAL INVESTIGATION WAS OPENED AND IS INVESTIGATING THIS BATTERY ISSUE. AN INTERNAL INVESTIGATION IS PENDING. A REPORT WILL BE SENT WHEN ROOT CAUSE FOR THE INTERNAL INVESTIGATION HAS BEEN DETERMINED. MEDTRONIC IS SUBMITTING THIS REPORT TO COMPLY WITH FDA REPORTING REGULATIONS UNDER 21 CFR PARTS 4 AND 803. THIS REPORT IS BASED UPON INFORMATION OBTAINED BY MEDTRONIC, WHICH THE COMPANY MAY NOT HAVE BEEN ABLE TO FULLY INVESTIGATE OR VERIFY PRIOR TO THE DATE THE REPORT WAS REQUIRED BY THE FDA. MEDTRONIC HAS MADE REASONABLE EFFORTS TO OBTAIN MORE COMPLETE INFORMATION AND HAS PROVIDED AS MUCH RELEVANT INFORMATION AS IS AVAILABLE TO THE COMPANY AS OF THE SUBMISSION DATE OF THIS REPORT. THIS REPORT DOES NOT CONSTITUTE AN ADMISSION OR A CONCLUSION BY FDA, MEDTRONIC, OR ITS EMPLOYEES THAT THE DEVICE, MEDTRONIC, OR ITS EMPLOYEE CAUSED OR CONTRIBUTED TO THE EVENT DESCRIBED IN THE REPORT. IN PARTICULAR, THIS REPORT DOES NOT CONSTITUTE AN ADMISSION BY ANYONE THAT THE PRODUCT DESCRIBED IN THIS REPORT HAS ANY ¿DEFECTS¿ OR HAS ¿MALFUNCTIONED¿. THESE WORDS ARE INCLUDED IN THE FDA 3500A FORM AND ARE FIXED ITEMS FOR SELECTION CREATED BY THE FDA TO CATEGORIZE THE TYPE OF EVENT SOLELY FOR THE PURPOSE OF REGULATORY REPORTING.
