The device was not returned for analysis.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 from this lot.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that resistance was met with the anatomy resulting in the reported difficult to advance.Interaction with the anatomy resulted in compromising the balloon material thus resulting in the reported inflation problem and the reported material rupture.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that the procedure was to treat the first marginal artery.A 3.5x8mm nc trek was able to be advanced to the lesion, however with some resistance met with the anatomy.Once at the lesion and pressurized once at 4 atmospheres, the balloon completely failed to inflate due to the balloon rupturing.The leak was noted coming from the balloon itself.There were no adverse patient effects and no clinically significant delay in the procedure.A non-abbott balloon and guideliner were used to successfully complete the procedure.No additional information was provided.
