It was reported the procedure was performed to treat a lesion in the left anterior descending coronary artery (lad).Prior to use, the mid-hypotube of the 2.5x15mm trek balloon dilatation catheter (bdc) was accidently bent.The user then straightened the bdc and inserted it into the anatomy.During the attempt to inflate, the bdc separated at the location of the bend.The separated segment was successfully snared.There was no adverse patient effect and no clinically significant delay in the procedure.A new trek bdc was used to complete the procedure.No additional information was provided.

Visual inspection was performed on the returned device.The reported separation and kink were confirmed.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history identified no other similar incidents and/or complaints from this lot.It should be noted that the coronary dilatation catheters (cdc), trek rx instruction for use (ifu), states: do not use, or attempt to straighten, a catheter if the shaft has become bent or kinked; this may result in the shaft breaking.Instead, prepare a new catheter.In this case, it is likely that the attempt to straighten and advance the kinked bdc into the anatomy contributed to the shaft separating.The investigation determined the reported kink appears to be related to operational context; however, the shaft separation appears to be related to user error.It was reported that even after a kink was noted, the device was advanced into the patient anatomy and the hypotube separated into two pieces.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.
