It was reported that during a procedure of the mildly tortuous, mildly calcified, 90% stenosed, bifurcation and distal right coronary artery (rca), after lesion pre-dilatation the 3.0 x 28 mm xience alpine stent delivery system (sds) was advanced but could not cross the lesion due to the anatomy.The xience alpine and a guideliner were re-inserted but could not cross the lesion due to the anatomy.Additional pre-dilatation of the lesion was performed; the xience alpine and guideliner were advanced but resistance was met with the guideliner and the sds did not cross the lesion due to the anatomy.The xience alpine sds met resistance with the guideliner during removal.Outside the anatomy the xience alpine sds mid shaft was noted to be stretched.The procedure was completed using a non-abbott drug eluting stent (des) without reported issue.There was no reported adverse effect and no reported clinically significant delay in the procedure.No additional information was provided.

(b)(4).Evaluation summary: the device was returned for analysis.The reported stretched shaft, difficulty to position and difficulty to remove were able to be confirmed.The reported failure to advance the device was unable to be replicated in a testing environment as it was based on operational circumstances.Based on a visual, dimensional and functional inspection of the returned device, there is no indication of a product quality issue with respect to manufacture, design or labeling.Based on the information provided, the reported difficulties appear to be related to circumstances of the procedure and not a product quality issue with respect to manufacture, design or labeling.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 did not indicate a lot specific quality issue.Based on the information reviewed, there is no evidence to indicate the presence a potential quality issue with respect to manufacture, design or labeling.
