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 similar incidents from this lot.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that resistance was met with the mildly calcified anatomy resulting in the reported difficult to advance.Additionally, the distal shaft was likely bent in the mildly calcified and steep aortic bifurcated anatomy preventing the shaft lumens from moving freely, thus resulting in resistance with the thumbwheel and the difficulty deploying the stent.Resistance with the steep aortic bifurcated anatomy resulted in the reported difficult to remove.Interaction with the sheath resulted in the reported difficult to remove and ultimately resulted in the reported stent dislodgement/reported foreign body in patient.Based on the information reviewed, there is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that on (b)(6) 2022, a percutaneous peripheral intervention was performed on the right common iliac artery, mildly calcified lesion.An absolute pro vascular stent delivery system (sds) advanced with difficulty due to the steep aortic bifurcation.Once at the right common iliac, deployment was attempted, however, the thumbwheel was difficult to turn and then stopped turning.The stent had only partially deployed.Standard troubleshooting was performed, retracting the sheath, however the issue remained.During sds removal, the device was difficult to remove due to the steep bifurcation and difficult to retract the stent into the non-abbott sheath.During removal attempt, the non-abbott outer sheath had separated, requiring snare for removal, and the partially deployed stent had dislodged.The partially deployed stent deployed fully at an unintended area, in the left common iliac artery.It was decided to leave the fully deployed stent at this location.A non-abbott stent was successfully implanted in the right common iliac artery.There was no adverse patient sequela, and there was no clinically significant delay reported.No additional information was provided.
