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 delivery catheter sheath, dilator, pusher wire and two cartridge.First cartridge filter was pre-loaded in the cartridge and second cartridge was empty when returned to argon.Most likely the second filter was implanted in the patient by the user.No damage was found on the product.Device was functionally evaluated and cartridge snapped fit with the delivery catheter sheath, pusher wire was used and the dilator advanced the filter, filter passed through the delivery catheter sheath without any issue, filter was loaded and removed in the cartridge multiple times without any issue and filter opened normally.Product complaint mode could not be duplicate during the evaluation and complaint was not confirmed.The most probable cause for the reported issue was most likely the result of the pusher wire or dilator not being fully centered during the procedure.Since the alleged complaint could not be duplicated with the returned device, no further evaluation will be taken.No corrective action is required at this time because a manufacturing defect could not be confirmed.
