A supplemental report is being submitted for device evaluation.Product event summary: the controller ((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.Visual inspection revealed bent pins within power port one (1).The bent pins did not allow a power source to properly connect to the controller.Log file analysis revealed two controller power up without motor starts on 02/jul/2022 at 13:13:49, 18/jul/2022 at 11:33:22 and three controller power up events with associated motor start event on 19/jul/2022 at 05:00:55, 05:01:22, 05:01:52, likely during the troubleshooting; followed by a controller power up event on 19/jul/2022 at 05:12:45.The data point prior to the last loss of power revealed that no power source was connected to power port one (1) and (b)(6) was connected to power port two (2) with 60% rsoc.The data point recorded after the last loss of power revealed that no power source was connected to power port one (1) and (b)(6) was connected to power port two (2).The controller was without power for 20 seconds.Additionally, alarm log file revealed three (3) vad disconnect alarms on 02/jul/2022 and 19/jul/2022 within analyzed period, likely due to physical disconnection of driveline from controller.These are incidental findings not related to the reported event.As a result, the reported bent pin event was confirmed.Based on an investigation conducted under capa pr00384004, the root cause of bent socket pins within power port connectors is attributed to misalignment during connection attempts between the metal receptacles on the controller and the plastic connector plugs in the battery and/or adapter cables.The misalignment results in wear on the connector plugs that can lead to contact between the connector plug and socket pins from the controller.The socket pins may not withstand applied forces from subsequent misaligned connections, causing the pins to bend.A possible root cause of the losses of power can be attributed to a disconnection of both power sources and/or to an intermittent disconnection on one or both power sources.Capa pr00551638 is investigating controller losses of power.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.
