The customer reported that the freedom driver of the patient at (b)(6) made a strange noise and the patient did not feel well.The customer also reported that the patient was subsequently switched to a backup freedom driver and that the patient felt better after the driver switch.The freedom driver was returned to syncardia for evaluation.Visual inspection of the exterior of the driver revealed no anomalies.Visual inspection of the interior revealed that a driveline connection clamp, fastening screw and lock washer were loose inside the housing.During investigation testing, the driver passed all test acceptance criteria, which included normotensive and hypertensive settings, with no anomalies or alarms.The driver was tested for an additional 48 hours at normotensive settings and performed as intended with no anomalies or alarms.The driver performed as intended, and there was no evidence of a device malfunction.The noise reported by the customer was likely caused by the loose hardwire inside the driver housing.The loose components met dimensional specifications, and it is unknown how the components became loose.The driver was serviced and returned to finished goods for clinical use.The reported issue posed a low risk to the patient because although the freedom driver exhibited a noise, 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.
