The customer reported that the freedom driver exhibited an irreversible fault alarm while supporting a patient.The küster also reported that the patient was rotating the onboard batteries in the freedom driver before going to bed.She inserted the onboard battery backwards, realized her mistake, and then turned the battery around, but was unsuccessful at resolving the fault alarm.The patient was plugged into ac power at the time of alarm.The patient was subsequently switched to the backup freedom driver without adverse impact.Although the freedom driver exhibited an irreversible fault alarm, the driver continued to function as intended.This alleged failure mode poses a low risk to the patient because it does not prevent the freedom driver from performing its life-sustaining functions.The freedom driver will be returned to syncardia for evaluation.The results of the investigation will be provided in a supplemental mdr.
