A review of the manufacturing and inspection records for this lot was conducted, and no deviations and non-conformances were recorded.Quality engineer and complaint analyst reviewed the sample returned from the customer.Customer returned filter (filter was removed from the cartridge) which was visually inspected and did not find any damage and filter opened normally without any issue.Product complaint mode could not be duplicated during the evaluation, because customer did not return any other supporting devices such as delivery catheter sheath, dilator, pusher wire and/or cartridge.Based on the evaluation of the returned device, this complaint could not be confirmed.Since the complaint was not confirmed, no corrective action is required at this time because a manufacturing defect could not be confirmed.
