The device was not returned to abbott vascular 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 and/or complaints reported from this lot.The device was prepped prior to use without any leak or ruptures noted, which would suggest that the device was not damaged prior to use.The investigation determined the reported balloon rupture, difficulty to remove, balloon separation and treatments appears to be related to operational circumstances of the procedure.In this case, it is likely that the balloon became compromised and/or damaged during advancement through the heavily calcified anatomy resulting in the reported balloon rupture.Due to the balloon rupture, the balloon did not properly refold likely resulting in the difficulty to remove with the anatomy.Manipulation against resistance ultimately resulted in the balloon separation and the use of a snare device to remove the separated segment of the balloon.There is no indication of a product quality issue with respect to manufacture, design, or labeling.
