The customer reported that the companion 2 driver exhibited a fault alarm while supporting a patient at the hospital (b)(6).The customer also reported that the patient was subsequently switched to the backup companion 2 driver.There was no reported adverse patient impact.The customer also reported that after the companion 2 driver was returned to the distributor, the driver did not pass the system check.This alleged failure mode poses a low risk to the patient because although the companion 2 driver exhibited a fault alarm, it did not prevent the driver from performing its life-sustaining functions.The companion 2 driver will be returned to syncardia for evaluation.The results of the evaluation will be provided in a follow-up mdr.

The customer reported that the companion 2 driver exhibited a fault alarm while supporting a patient at the hospital (b)(6).The customer also reported that the patient was subsequently switched to the backup companion 2 driver.There was no reported adverse patient impact.The customer also reported that after the companion 2 driver was returned to the distributor, the driver did not pass the system check.The companion 2 driver was returned to syncardia for evaluation.Visual inspection of the driver's external components revealed no anomalies.The patient file was copied and reviewed, which revealed one system malfunction alarm that resulted from an "internal filter blocked" trigger value and one system check failure.The customer experience was confirmed.During investigation testing, the customer-reported system malfunction alarm and the system check failure were duplicated.The root cause was a malfunction of the pressure sensor printed circuit assembly (pca).Despite the customer-reported system malfunction alarm and system check failure, risk to the patient was low because the driver continued to perform its life-sustaining functions.After replacement of the pressure sensor pca, the driver met all performance testing requirements.The driver was serviced before being released to finished goods.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.
