(b)(4).Internal file number (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, instructions 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.In this case, it is likely that the attempt to advance the bent bdc into the anatomy contributed to the shaft separating as further handling/manipulation was encountered at the bent location.The investigation determined the reported bend 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.
