The customer reported that the freedom power adaptor exhibited a green blinking light instead of a solid green light when the freedom driver was connected to wall power.The patient subsequently switched the freedom power adaptor to the backup freedom power adaptor.There was no reported adverse patient impact.The freedom power adaptor s/n (b)(4) was returned to syncardia for evaluation.Visual inspection of the power adaptor did not reveal any abnormalities or anomalies.The power adaptor was functionally evaluated and passed all functional and mechanical tests.Further evaluation of the power adaptor, while connected to a freedom driver and ac wall power, was performed with onboard batteries of different charge levels.The power adaptor performed as intended, and there was no evidence of a device malfunction.The blinking of the freedom power adaptor green led as reported by the customer could not be duplicated.The reported issue posed a low risk to the patient because it did not prevent the freedom driver from performing its life-sustaining functions.In addition, the freedom driver is equipped with redundant power sources, including multiple rechargeable freedom onboard batteries and an external battery charger.Because freedom power adaptor s/n (b)(4) met the test acceptance criteria, it was returned to inventory.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.
