It was reported that the procedure was to treat a heavily calcified, 90% stenosed lesion in the right superior femoral artery (sfa).Pre-dilatation was performed, but the lesion was remained very calcified.The 4.5x150mm supera peripheral self-expanding stent system (sess) was advanced and deployed, after which the tip of the stent delivery system became stuck in the heavily calcified plaque and separated in the anatomy as the delivery system was being removed.A snare was used to remove the detached tip from the anatomy without issue to successfully complete the procedure.There was no adverse patient sequela and no reported clinically significant delay in the procedure or therapy.No additional information was provided.

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.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that during removal resistance was met with the heavily calcified and 90% stenosed anatomy resulting in the reported difficult to remove.Manipulation of the device ultimately resulted in the reported tip material separation.The treatment appears to be related to the operational context of the procedure as a snare was used to remove the detached catheter tip from the anatomy without issue to successfully complete the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling.
