The freedom driver was returned to syncardia for evaluation.Visual inspection of the driver revealed split and damaged housings, raised inserts, loose hardware, scuff marks on the primary motor and main printed circuit board assembly (pcba), and a broken u21 sensor.The customer-reported alarm was confirmed in the driver alarm history, but was not able to be duplicated during the investigation process.The "06" alarm code (the alarm code most likely experienced by the customer) was not reproduced because it likely originated in the field as a result of the impact shock sustained by the driver.A "4b" alarm code, correlating with a u21 pressure sensor malfunction, was produced during incoming functional testing of the driver.The broken u21 pressure sensor supports the assertion of an impact shock/jolt or rough handling to the driver.The root cause of the customer reported issue could not be determined, but the damage to the driver observed during the visual inspection suggests improper use.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) follow-up report 1.
