Driver passed incoming functional testing.Visual inspection of external components found no evidence of damage or abnormalities.Visual inspection of internal components found the secondary motor out of the default position.Review of alarm history data found three alarms recorded in the driver's eeprom.The first two alarms were confirmed to have been produced at syncardia during functional test during the last service interval.The third alarm, can occur as a result of secondary motor engagement.Additional testing was performed at both normotensive and hypertensive setting in order to replicate the customer reported fault alarm.During the testing, the driver operated as intended.No permanent alarms occurred; no device malfunction was identified.The investigation was able to confirm the customer reported fault alarm through visual inspection and alarm history review.Inspection of internal components found the secondary motor out of the default position and a fault alarm was recorded in the alarm history.Both of these events are indicative of secondary motor engagement.When the secondary motor engages, the driver goes into permanent fault alarm requiring the driver to be removed from the patient.The driver is designed to switch to secondary motor operation but it is not intended to provide ongoing patient support while operating on the secondary motor.Operation switch from primary to secondary motor is not a device malfunction.This issue will be monitored and trended as part of the customer complaint process.Syncardia has completed its evaluation and is closing this file.If new or additional information is received in the future, syncardia will file a follow-up mdr.(b)(4) follow-up report #1.
