The device was not returned for analysis.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.It is possible that the distal shaft was bent in the anatomy preventing the shaft lumens from moving freely, resulting in resistance with the thumbwheel and difficulty deploying the stent; however this cannot be confirmed.The investigation determined a conclusive cause for the reported mechanical jam and activation/deployment failure cannot be determined.As reported, an attempt was made to remove the device including the stent, but the stent deployed in the left common femoral artery resulting in the reported device dislodged/dislocated and reportedly the stent was left there.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that during a left superficial femoral artery intervention, the 6x100mm absolute pro vascular stent system was advanced to the lesion and deployment attempted but the thumbwheel stopped turning after the stent was exposed and flowered, so an attempt was made to remove the device including the stent, but the stent deployed in the left common femoral artery and was left there.There was no adverse patient sequela or a clinically significant delay in procedure.A second absolute pro vascular was implanted without issue in the target lesion.No additional information was provided.
