Additional Manufacturer Narrative
A supplemental is being submitted for additional information.Product event summary: the battery (b)(6) was returned for evaluation.Various analyses were conducted and reviewed to evaluate the performance of the device in relation to the reported event.Review of the manufacturing documentation confirmed that the associated device met all requirements for release.Log file analysis pertaining to (b)(6) revealed no anomalies throughout the analyzed period.Failure analysis of the returned device revealed that the battery 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.As a result, the reported event was confirmed.(b)(6) is in scope of fa1265, which was initiated for batteries with electrical faults.Based on an investigation conducted under capa pr00519785, the most likely root cause of the reported event has been attributed to the battery connector interface design which does not guarantee the desired connection angle in some use conditions.Investigation of this event is completed and the file will be closed.If new information is received, the file will be re-opened and a supplemental will be submitted.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.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
