It was reported that during a procedure of the non-tortuous, mildly calcified, posterior tibial artery, the xience xpedition stent delivery system failed to reach the lesion.During removal, without resistance, the shaft separated and the stent moved on the balloon.It was noted that the sheath was intentionally detached at the access site in order to remove the stent delivery system from the anatomy.Upon removal, it was noted that the distal shaft, from the guide wire exit notch to the mid lap joint, was stretched, torn and twisted.The procedure was completed using a second device without reported issue.There was no adverse patient effect or a clinically significant delay in procedure reported.No additional information was provided.

(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.(b)(4).Evaluation summary: the device was returned for analysis.The shaft separation was able to be confirmed.The stent dislodgement was unable to be confirmed; however, the stent was noted to be mislocated on the balloon and follow up information confirmed the correct device was returned.The failure to advance and difficult to remove could not be replicated in a testing environment as it was based on operational circumstances.Based on a visual 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.
