It was reported that the procedure was to treat a heavily tortuous, heavily calcified left anterior descending artery.Pre-dilatation was done using nc balloons.A 2.75x23mm xience alpine was being advanced but failed to cross due to anatomy and became stuck, continued attempts were made to advance but the shaft kinked.The xience alpine was able to be simply withdrawn and replaced with another xience alpine to successfully complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

A visual, dimensional, and functional inspection was performed on the returned device.The reported deformation due to compressive stress was confirmed.The reported failure to advance and difficult to remove could not be evaluated as the exact anatomical conditions encountered by the device used during the procedure could not be replicated in the test laboratory.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.The reported difficulties appear to be related to the operational context of the procedure.There is no indication of a product quality issue with respect to manufacture, design, or labeling of the device.
