Additional Manufacturer Narrative
Product event summary: the battery was returned for evaluation.No device malfunction was reported against the battery, therefore the purpose of this analysis is solely to evaluate the device conformance to internal release requirements and/or to identify anomalies potentially introduced during use that may have prevented the device from performing as intended.Functional testing revealed that the battery was unable to charge on a test battery charger or provide power to a test controller.During functional testing, test equipment was unable to read the battery status due to a communication problem with the main integrated circuit.Supplemental testing revealed that the analogue front end integrated circuit (afe ic), that measures cell pair voltages, is not providing enough voltage to the main integrated circuit, rendering the battery inoperable.The battery was in scope of fa1265.Based on an investigation conducted under capa (b)(4), 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.Additional information has been requested regarding patient demographics, but it was not available at the time of this report.If additional information is received, the event will be updated and a supplemental report will be sent.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.
