It was reported that the procedure was treating a heavily tortuous, heavily calcified, 90% stenosed, de novo lesion in the proximal to mid left anterior descending coronary artery.The 2.5x18 xience xpedition stent delivery system (sds) was advanced; however, failed to cross due to the patient anatomy.Pre-dilatation was performed several times and the sds was advanced again, but still failed to cross the lesion.The device was removed from the anatomy and a non-abbott sds was used to complete the procedure.It was noted by the physician that the polymer on the stent implant may be coming off.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

(b)(4).Evaluation summary: the device was returned for analysis.The peeling was able to be confirmed.The failure to advance could not be replicated in a testing environment as it was based on operational circumstances.Based on a visual and dimensional inspection of the returned device, there is no indication of a product deficiency.A review of the lot history record revealed no non-conformances that would have contributed to the reported event.A query/review of the complaint history of the reported lot did not indicate a manufacturing issue.Based on the reviewed information, no product deficiency was identified.
