Manufacturer Narrative

Device history record (dhr) review confirmed that companion 2 driver s/n 10071a was serviced and passed all functional testing prior to being released to finished goods.Alarm history and patient data file review found two new alarms, system malfunction and left vacuum incorrect, in driver's data file.Visual inspection of external and internal components found no abnormalities.Driver passed all areas of functional testing for acceptance at incoming inspection.Observational testing identified that the driver alarmed during the transition from higher to lower vacuum settings and vice versa at patient settings during recorded complaint.A known functional sensor board was installed and functioned without alarm or issue at reported patient settings.This test was repeated with a separate known functional sensor board with the same result.Initial sensor board was installed in a known functional companion 2 driver and failed at the same settings, replicating the original complaint.Failure investigation for this complaint confirmed the reported issue.The customer complaint was replicated during testing; the root cause of the reported system malfunction alarm was determined to be a faulty pressure sensor board.Failure investigation identified no other test failures or damage that could have contributed to the complaint.Patient was switched to a backup driver without any reported adverse impact.This issue will be monitored and trended as part of the customer complaint process.Syncardia has completed its evaluation and is closing this file.If new or additional information is received in the future, syncardia will file a follow-up mdr.
