It was reported that the procedure was to treat a lesion in an unspecified coronary artery.During prep, visual and tactile inspection were performed on a 014 balance middleweight (bmw) 3cm guide wire and a little step was noted 30 cm from the distal tip.The bmw device was advanced into the patient anatomy.When advancing a non-abbott stent delivery system (sds) over the bmw, the sds was unable to be advanced past the step on the bmw and was also difficult to retract from that step.All devices were removed from the anatomy as a single unit.The bmw guide wire was replaced with a new unspecified guide wire to complete the procedure.There were no adverse patient effects and no occurrence of a clinically significant delay.No additional information was provided.
