This freedom driver was not supporting a patient.The customer reported that both onboard batteries could be removed from the freedom driver at the same time, instead of one of the onboard batteries being locked in place when the other onboard battery was removed.The freedom driver was returned to syncardia for evaluation.Visual inspection of the exterior and interior components of the driver revealed no abnormalities.The battery release latches and battery safety latches in the battery wells were inspected and no visual defects were found.During investigation testing, functional testing confirmed proper operation of the battery release latches and safety latches.The reported issue could only be reproduced by not fully inserting an onboard battery in a manner that allowed the onboard battery to make connection to power the driver and engage the battery safety latch without engaging the battery release latch.This method allowed the release of both onboard batteries.The investigation concluded that there was no evidence of a device malfunction and that the freedom driver performed as intended.The onboard batteries utilized by the customer at the time of the reported issue were not returned to syncardia and could not be evaluated as part of this investigation.It is possible that the onboard batteries could have been the cause of the reported issue.The freedom driver was serviced.The reported issue posed a low risk to a patient because the issue was observed when the freedom driver was not supporting a patient.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.
