The freedom driver was returned to syncardia for evaluation.Review of the driver's alarm history revealed a single new documented alarm (alarm code 36), which was likely one of the alarms experienced by the customer.This was the only alarm logged by the driver (temporary/recoverable alarms are not logged).Alarm code 36 can be produced during power cycling of the freedom driver, during onboard battery exchange while operating only on battery power, or if an onboard battery is not fully latched in place.The driver passed all incoming and functional test requirements with no anomalies or alarms.Additionally, an extended observation run and a battery insertion/extraction test, was performed and the driver functioned as intended with no evidence of a device malfunction.The customer reported alarms couldn't be reproduced during investigation testing; therefore, a root cause for the reported issue was not determined.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.(b)(4).
