It was reported that the procedure was performed to treat a 30% stenosed, moderately tortuous, and moderately calcified de novo lesion in the right iliac artery.The balloon of a 7x80mm armada 35 balloon catheter ruptured during the first inflation before reaching around 4 atmospheres.The procedure was successfully completed with a new 7x80mm armada 35 balloon catheter.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

Visual analysis was performed on the returned device.The reported 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 incidents.The investigation determined that the reported difficulties were likely due to case related circumstances.It is likely that the balloon interacted with the lesion calcification causing damage to the outer surface of the balloon material which subsequently ruptured during inflation.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
