A visual inspection was performed on the returned device.The balloon rupture was 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 and/or complaints from this lot.It should be noted that the coronary dilatation catheters (cdc), nc trek rx, global, instruction for use states: balloon pressure should not exceed the rated burst pressure (rbp).The investigation determined the reported balloon rupture appears to be related to the violation of the ifu as the nc trek bdc was over inflated to 20 atmospheres (atms) multiple times.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.
