The device was returned for analysis.The reported mechanical jam and the reported activation failure were able to be confirmed.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.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 circumstances of the procedure.It is likely that during advancement interaction with the aortic bifurcation which was reported as very tight coming up and over resulted in the noted chatter mark indentations along the entire length of the sheath preventing the shaft lumens from moving freely thus resulting in the reported thumbwheel difficulties and the reported difficulty deploying the stent.Interaction and/or manipulation of the compromised device resulted in the noted gap between the outer member and the sheath and the noted bunched stabilizer jacket likely contributing to the reported/noted difficulties.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that the procedure was performed to treat a lesion in the right external iliac artery.The 7.0x40mm absolute pro self expanding stent system (sess) was attempted to be released; however, the thumbwheel wouldn't move.The stent completely failed to deploy.Another absolute pro v was used to complete the procedure.There were no adverse patient effects and there was no clinically significant delay in the procedure.Returned device analysis identified that the stent was partially deployed and flowered; however, the account stated that they were not aware of the exposure.No additional information was provided.
