It was reported that the procedure was to treat a lesion in the left anterior descending coronary artery.The 3.50x15 mm nc trek balloon dilatation catheter (bdc) was loaded onto the guide wire, however when inserting the bdc into the guide catheter the shaft kinked and separated into two pieces outside of the patient anatomy.There was no resistance noted during advancement of the bdc into the guiding catheter.The device never exited the catheter, and due to some resistance removing the separated shaft, all devices were removed together as a single unit.A new trek bdc was used to complete the procedure.There were no adverse patient effects and no clinically significant delay during the procedure.No additional information was provided.
