It was reported that the procedure was to treat a moderately tortuous and moderately calcified bifurcation of the superficial femoral artery.Pre-dilatation was performed with a 6.0 x 150 mm non-abbott balloon catheter at nominal pressure.There was resistance with the anatomy when advancing an 8.0 x 150 mm supera self-expanding stent system to the lesion.After deploying 30-40 mm of the stent, the thumbwheel ratchet would not engage and it could not be moved forward or backwards.While removing the delivery system, including the stent, when the tip was pulled into the 6f sheath, the tip stuck and the shaft and tip separated so the entire system was removed from the anatomy.After attempting to use two non-abbott devices, an absolute pro self-expanding stent was successfully deployed to complete the procedure.There was no clinically significant delay in procedure and no adverse patient effects.No additional information was provided.
