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 similar incidents from this lot.As the balloon markers were visible during cine review by abbott vascular, the investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that due to the highly dense material of the guide wire and occasional difficulties under certain frames per second resulted in rendering the balloon markers difficult to see (reported difficult or delayed positioning/visibility).Based on the information reviewed, there is no indication of a product quality issue with respect to manufacture, design or labeling.
