Additional Manufacturer Narrative
A supplemental report is being submitted for investigation summary.Product event summary: the controller (b)(6) was not returned for evaluation.A review of the device history record was not performed as the reported event and analysis is not related to a manufacturing or servicing issue.Log file analysis revealed twenty-nine (29) controller fault alarms logged since 23/jun/2025, indicating an issue with the internal battery.In addition, log files revealed that the controller had been in use for more than two (2) years.Log file analysis also revealed eleven (11) low flow alarms logged since 27/jun/2025.The low flow alarms are an additional finding, unrelated to the reported event.As a result, the reported event was confirmed.Based on the limited information available, the device may have caused or contributed to the observed low flow finding.Based on the risk documentation, possible causes of the observed low flow finding may be attributed to multiple factors including but not limited to thrombus at the inflow cannula/outflow graft, constriction at the outflow graft, poor vad filling, and/or inappropriate pump rotational speed.Applicable risk documentation, experience with events of similar circumstances, and the available information were considered; possible root causes of the reported controller fault alarm event may be attributed, but not limited, to a reduced charge capacity of the internal battery and/or a faulty internal battery charger integrated circuit.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 submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide 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.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.Medtronic will submit a supplemental report if additional relevant information becomes known.
