It was reported that the procedure was to treat a lesion located in the 1st diagonal in the left anterior descending (lad) coronary artery that was heavily calcified.Reportedly, the nc trek neo rx 3.00 x 12mm was advanced first in the distal lad.Then, the xience skypoint des 2.75 x 18 rx us stent delivery system was unable to advance out of the guide catheter.The physician lost guide engagement and wire position, and pulled both devices into the guide catheter.Once the guide catheter was re-engaged, and the physician had wire placement, the nc trek neo was re-advanced into the distal lad (but not inflated).The sds was unable to advance, with resistance.Then the sds was removed and noticed that the stent had separated from the shaft outside the patient.The nc trek neo appeared to be kinked on the shaft.Both devices were not able to be used and set aside.A new stent and balloon of the same size were opened and successfully used.There were no reported adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.
