It was reported that the procedure was to treat a 99% stenosed, mildly tortuous lesion in the mid third circumflex coronary artery.Reportedly, a 2.00x12mm mini trek rx balloon dilatation catheter (bdc) presented a defect on its proximal edge portion of a non smooth surface, making it difficult to advance the guide wire and consequently failed to inflate the balloon.The procedure was successfully completed with an unspecified stent delivery system.There was no clinically significant delay in the procedure and no adverse patient sequela.No additional information was provided.The return device analysis identified that the inner member and outer member were stretched.

The device was returned for analysis.The reported product quality problem/ irregular texture was unable to be confirmed; however there was noted inner and outer member damages (stretched, wrinkled, smashed).The reported difficult to advance and the reported inflation problem were able to be confirmed.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.As there was no damage noted to the device during the inspection prior to use, the investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that inadvertent mishandling and/or manipulation of the device resulted in the reported product quality problem irregular texture/noted inner and outer member damages (stretched, wrinkled, smashed) thereby compromising the inflation lumen; thus resulting in the reported difficult to advance and the reported inflation problem.There is no indication of a product quality issue with respect to manufacture, design or labeling.
