(b)(4) our manufacturing quality engineer received one (1) sample from lot #0001141884 for evaluation.During visual inspection the device was noted to be twisted and deformed therefore, not allowing functional testing to be performed.Therefore, the reported failure mode could not be confirmed.Additionally, an internal review of the history files was completed for the reported lot number manufactured on 16-aug-2017 confirming procedural and functional requirements needed for the product to be released were met.As reported failure mode could not be confirmed during analysis, a root cause was not determined an immediate action will not be proposed.The failure mode will be entered into the complaint management system and will be tracked/trended for any additional similar failure modes.Customer complaint trends are evaluated on a monthly basis during our quality team meeting.If the trend of a specific type of complaint warrants a formal corrective action, resources will be assigned at that time.
