Visual and functional inspections were performed on the returned device.The reported inflation issue was confirmed.Additionally, an attempt was made to pressurize the balloon to rated burst pressure (rbp) of 14 atmospheres, and a leak was observed coming from a balloon pinhole located distal to the balloon proximal marker band, confirming the reported inflation issue 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.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 anatomy such that the balloon became damaged, ruptured, and subsequently resulted in the reported inflation issue.The investigation determined the reported inflation issue and noted balloon rupture appear to be related to operational context.There is no indication of a product quality issue with respects to the design, manufacture, or labeling of the device.

It was reported that the procedure was performed to treat a target lesion in the heavily calcified circumflex (cx) artery.A non-abbott rotational athetectomy device was used, then the 2.5 x 30 mm trek dilatation catheter was advanced to the target lesion.The trek dilatation catheter balloon was inflated to 13 atmospheres (atm), then would not inflate any more.There was no leak noted and no balloon rupture was suspected, as there was no bleed back noted.The balloon seemed to be fully inflated and the balloon deflated without issue.The device was removed without difficulty and there was no adverse patient effect.Additional rotational atherectomy was performed, and an nc trek was then used without issue.There was no adverse patient effect and no clinically significant delay reported.Returned device analysis indicates that a leak was observed in the dilatation catheter balloon.Additional follow up with the site indicated that no leak was noted by the physician.No additional information was provided.
