(b)(4).The device was not returned for analysis.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history of the reported lot revealed no other incidents.The supera instruction for use states that the device is indicated for use in the superficial femoral artery (sfa) and / or proximal popliteal artery.It could not be determined if using the supera in the iliac contributed to the reported difficulties.Based on the reported information, it is likely that the introducer sheath was positioned too close to the supera stent during deployment, contributing to the reported difficulties.The investigation determined that the difficulties were due to operational context.There is no indication of a product quality issue with respect to the design, manufacture or labeling of the device.

It was reported that the patient underwent a peripheral procedure to treat a target lesion in the moderately calcified and tortuous iliac artery.During deployment, the supera stent deployed in the sheath and pinned the nosecone.The stent delivery system was pulled and the nosecone separated.The stent was fully deploy at the target lesion without further difficulty.A snare was advanced to capture the separated nosecone; however, the nosecone could not be pulled into the sheath.An unspecified covered stent was deployed to crush the nosecone to the vessel wall, proximal to the deployed supera stent and in the lesion that was planned to be stented.There was no clinically significant delay and no adverse patient sequelae.No additional information was provided.
