This companion 2 driver was not supporting a patient.The customer reported that when he switched on the companion 2 driver, it did not boot up, it started pumping immediately and showed a computer firmware screen with setup from the main board.The customer also reported that the driver could not be switched off, and the driver continued to pump until the internal emergency battery depleted.The companion 2 driver was returned to syncardia for evaluation.Visual inspection of the driver's external and internal components revealed no anomalies.During failure investigation testing, the boot up issue, as observed by the customer, was reproduced.It was determined that the 3-volt battery installed on the main board printed circuit assembly (pca) was depleted.The normal service cycle for the 3-volt battery is every two calendar years.Since the 3-volt battery was depleted after 79 days of driver use, it is possible that there was an issue with the main board pca that led to the premature depletion.As a result, both the 3-volt battery and the main board pca were replaced.The driver was serviced before being released to finished goods.This alleged failure mode poses a low risk to a patient because the issue was observed when the companion 2 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.
