It was reported that during a procedure of the mildly tortuous, mildly calcified de novo, mid left anterior descending artery the 2.5 x 48 mm xience xpedition stent was implanted without issue.A 2.5 x 18 mm xience xpedition stent delivery system (sds) was advanced through the implanted stent, for treatment of the moderately tortuous, non-calcified, de novo, proximal diagonal artery; however, it became stuck in the implanted stent struts and had to be removed.During removal of the sds, it damaged the implanted stent struts and pulled the implanted stent from its site and dislodged.Both stents were removed with a snare device.A different 2.5 x 48 mm xience xpedition stent was implanted in the distal lad and a 3.0 x 20 mm non-abbott stent was implanted in the proximal lad, overlapping.The final outcome was reported as good.There was no reported adverse patient sequela or a clinically significant delay in the procedure.No additional information was provided.

(b)(4).Evaluation summary: the device was returned for analysis.The reported device damaged by another device, stent migration and material deformation were unable to be confirmed as only the stent delivery system (sds) without the stent was returned.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 from this lot.The investigation determined the reported difficulties appear to be related to circumstances of the procedure.Based on the information reviewed, there is no indication of a product quality issue with respect to the design, manufacture or labeling of the device.
