The customer reported that the freedom driver exhibited fluctuating fill volumes and output while supporting a patient.The customer also reported that the patient had intermittent fault alarms.The customer also reported that the patient was subsequently switched to the backup freedom driver.There was no reported adverse patient impact.Visual inspection of the driver's external components revealed no abnormalities.Visual inspection of the driver's internal components revealed multiple fractures on three of the bosses of the front housing.The bosses could have fractured as a result of normal use and are not the cause of the customer-reported issue.The front housing will be replaced upon servicing of the driver.The driver's electronic alarm history data was retrieved, there were no new alarms recorded.Only permanent fault alarms are recorded in the driver's alarm history.Intermittent, recoverable and battery alarms are not recorded in the electronic alarm history data.The driver in "as received" condition passed all test requirements associated with normotensive and hypertensive settings with no anomalies or alarms.The driver was tested for an additional 48 hours, and the driver functioned as intended with no alarms or anomalies in fill volumes and cardiac output.It is likely that the customer-reported issues were the result of the patient's condition at the time of the customer experience.The driver performed as intended, and there was no evidence of a device malfunction.This alleged failure mode poses a low risk to the patient because although the freedom driver exhibited fluctuating fill volumes and intermittent fault alarms, the freedom driver continued to perform its life-sustaining functions.The freedom driver was serviced and passed all functional and performance testing prior to being released into finished goods.This issue will continue to be monitored and trended as part of the customer experience process.Syncardia has completed its evaluation of this complaint and is closing this file.
