It was reported that the procedure was to treat a lesion in the proximal left circumflex (lcx) artery with moderate tortuosity, moderate calcification and 100% stenosis.A proturn guide wire was advanced to the lesion without resistance; however, while an unspecified device was advanced over the guide wire the tip caught slightly with the lesion and the tip shape became bent/curved in an undesirable shape.The proturn guide wire was removed from the patient anatomy, slight resistance was felt with the lesion and the tip was re-shaped; however, the tip could not be re-shaped properly.Thus, the proturn guide wire was replaced with a non-abbott guide wire.There was no reported adverse patient effect and no reported clinically significant delay in the procedure.No additional information was provided.
