The device was not returned to abbott vascular for analysis.Return of the device may have further aided the 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 and/or complaints reported from this lot.Possible factors that may contribute to balloon leaks or pinhole ruptures may include, but are not limited to, balloon damage during processing of the balloon material, inflation technique, inflation over rated burst pressure, interactions with other devices, anatomical conditions, a previously implanted stent or insufficient preparation prior to use.The device was prepped prior to use without any leak noted, which would suggest that the device was not damaged prior to use.The investigation was unable to determine a conclusive cause for the reported balloon rupture.It is possible that during advancement or multiple inflations the outer surface of the balloon became compromised or damaged against the anatomy and/or other devices used resulting in pinhole balloon rupture and the appearance of a balloon leak; however, this could not be confirmed.There is no indication of a product quality issue with respect to manufacture, design or labeling.
