On 04 february 2016, the customer reported that the freedom driver exhibited temperature alarms while supporting a patient.The customer also reported that the patient was subsequently switched to the backup freedom driver.There was no reported adverse patient impact.The freedom driver was returned to syncardia for evaluation.Review of the alarm history (eeprom) revealed one alarm code that likely occurred during the driver exchange.Only permanent fault alarms are recorded in the eeprom.Intermittent, recoverable and battery alarms are not recorded in the eeprom.Visual inspection of the driver revealed split housings, a broken housing boss and a raised housing boss at the top right of the housing, which indicated that the driver was subjected to an impact shock.The driver was functionally tested, and despite the damage to the housing, the driver passed all test acceptance criteria, which included pressure test requirements associated with normotensive and hypertensive settings, with no anomalies and no alarms.The exhaust fan was also confirmed to function as intended during functional testing.The root cause of the reported temperature alarms could not be conclusively determined.During investigation testing, the freedom driver performed as intended, and there was no evidence of a device malfunction.The driver was repaired and serviced and passed all final performance testing.The reported issue posed a low risk to the patient because although the freedom driver exhibited temperature alarms, the freedom driver continued to perform its life-sustaining functions.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.
