(b)(4).Date sent: 7/24/2023.D4: batch # x9673l.Investigation summary: the product was returned to ethicon for evaluation.Visual inspection and functional testing were conducted on the returned device.Visual analysis of the returned sample determined that the el5ml device was returned with a trocar inserted and one jaw disengaged from the cam; this condition would not allow the jaws to collapse in order to form the clips.In addition 2 clips jammed were noted to be jammed inside the shaft.The clips were removed in order to perform functional testing.In an attempt to replicate the reported incident, the device was tested for functionality.In order to evaluate the performance of the device, the jaw was readjusted and in the next actuations, 6 conforming clips were fed and formed; finally the device locked out as intended.However it is known from the history of the device that jaw disengaged condition may lead to malformed clips.Possible causes for the condition of the jaw disengaged from the cam may be inadvertent force, twisting or pressure being placed on the device jaws, using the jaws of the device as a dissector/retractor or damage to the jaws while entering the trocar.Although no conclusion could be reach on the cause of the reported event, the instructions for use contain the following caution: insert the clip applier through an appropriately-sized trocar.The empty jaws will passively collapse as they are inserted through a 5 mm trocar and reopen when completely through the trocar.Prior to loading a clip in the jaws and firing the instrument: ensure that the jaws are fully open by verifying that the line of demarcation between the jaws and the instrument shaft is past the distal end of the trocar cannula.Prior to positioning the jaws around the tubular structure or vessel, load a clip into the jaws by partially squeezing the trigger in a smooth continuous motion for approximately one-third of the total firing stroke.Position the jaws with the preloaded clip completely around the tubular structure or vessel to be ligated.The structure to be ligated should be positioned against the apex of the clip.As part of ethicon¿s quality process, all devices are manufactured, inspected, and released to approved specifications.A manufacturing record evaluation was performed for the finished device batch and lot number, and no non-conformances were identified.
