The device was returned for analysis.The reported activation failure was able to be confirmed.The reported mechanical jam and noise and were unable to be replicated in a testing environment due to the condition of the returned device.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents from this lot.Reportedly, a command.014¿ 300 cm guide wire was used.Use of an undersized guide wire, with insufficient support, may cause kinking in the stent delivery system.It should be noted the absolute pro vascular self-expanding stent system instructions for use (ifu) under materials required, states: one 0.035" (0.89 mm) diameter guide wire.As there was no damage noted to the device during the inspection prior to use, the investigation determined the reported difficulties appear to be related to deviation of the instructions for use and subsequent circumstances of the procedure as it is likely that during advancement use of the undersized.014¿ guide wire in conjunction with interaction with the mildly calcified anatomy resulted in the noted device damages (multiple sheath chatter marks, kinked inner member) preventing the shaft lumens from moving freely; thus resulting in the reported thumbwheel clicks/thumbwheel jam during attempted stent deployment.Manipulation of the compromised device resulted in the noted stretched tip and inner member and the noted separated sheath and jacket likely contributing to the reported difficulties.Removal of the compromised device resulted in the noted stent damages (broken/flared/stretched struts).There is no indication of a product quality issue with respect to manufacture, design or labeling.H6: medical device problem code: code 1484 was deleted, 3270 and 2983 and 2017 added.
