(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.(b)(4).The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other similar incidents from this lot.It should be noted that the nc trek rx, instruction for use 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 the kink contributed to the shaft separating.The investigation determined the reported kink appears to be related to circumstances of the procedure; however, the shaft separation appears to be related to user error.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.

It was reported that the 3.0x12mm nc trek rx balloon dilatation catheter (bdc) shaft was noted to be kinked as it was loaded onto an unspecified guide wire.The bdc hypotube broke in two separate pieces when the kink was attempted to be straightened out.The separation occurred outside the body before the bdc was inserted into the patient.The bdc was removed from the guide wire without issue, and a new 3.0x12mm nc trek was used to successfully complete the procedure.There were no reported adverse patient effects, and there was no reported clinically significant delay in the procedure.No additional information was provided.
