The reported issue involves two freedom onboard batteries and are reported under two separate medical device reports: freedom onboard battery s/n (b)(4) (mfr report # 3003761017-2015-00049) and freedom onboard battery s/n (b)(4) (mfr report # 3003761017-2015-00050).The customer reported that the freedom onboard batteries were unable to hold a charge on the freedom driver while supporting a patient.The patient subsequently exchanged the freedom onboard batteries.There was no reported adverse patient impact.This alleged failure mode poses a low risk to the patient because although the freedom onboard batteries were unable to hold a charge, it did not prevent the freedom driver from performing its life-sustaining functions.In addition, patients are provided with several onboard batteries, and the freedom driver has a redundant power source of external wall power.The freedom onboard batteries will be returned to syncardia for evaluation.The results of the investigation will be provided in supplemental mdrs.
