It was reported that the procedure was to treat a lesion in the anterior tibial artery with 90% stenosis, heavy calcification and heavy tortuosity.The 2.5x200mm armada 14 balloon dilatation catheter (bdc) was advanced without resistance, however, it ruptured at a pressure of 8 atmospheres (atms) during the first inflation.Another 2.5x120mm armada 14 balloon was used to complete the procedure.There was no adverse patient effect and there was no clinically significant delay in the procedure.No additional information was provided.

Visual and functional inspections were 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 similar incidents and/or complaints from this lot.The investigation determined the reported balloon rupture appears to be related to operational context.Balloon material ruptures can be affected by numerous factors including, but not limited to, balloon damage during processing of the balloon material, materials, inflation technique, and interactions with other devices or lesion calcification.There was no leak noted during preparation, which suggests a product quality issue did not contribute to the reported difficulties.In this case, it is likely that the balloon interacted with the heavily calcified and heavily tortuous anatomy such that the balloon became damaged (scratched) and subsequently ruptured during inflation.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.D4: lot number updated from 1050641 to 2062741.
