It was reported that using a femoral artery access approach during a procedure of the heavily tortuous, heavily calcified, 90% stenosed, mid left anterior descending artery (lad), the 3.5 x 15 mm xience xpedition stent delivery system (sds) was advanced but could not cross the lesion.It was noted that a parallel guide wire technique was utilized with the sds but it still could not cross the lesion after several attempts.The sds was removed and outside the anatomy it was noted that the stent implant was tightly crimped but moved 2-3 mm proximal on the balloon.The device was not used again.A non-abbott sds was used to complete the procedure without issue.There was no reported adverse patient effect.There was no reported clinically significant delay in the procedure.No additional information was provided.

(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.Concomitant products: guide wire: sion blue; guide catheter: luncher ebu 3.0.(b)(4).It is indicated that the device is not returning for evaluation; therefore, a failure analysis of the complaint device could not be completed.It should be noted that the xience xpedition everolimus eluting coronary stent system instructions for use (ifu) states: an unexpanded stent may be retracted into the guiding catheter one time only.An unexpanded stent should not be reintroduced into the artery once it has been pulled back into the guiding catheter.Subsequent movement in and out through the distal end of the guiding catheter should not be performed as the stent may be damaged or / and dislodged from the balloon when retracting the undeployed stent back into the guiding catheter.A review of the lot history record revealed no non-conformances that would have contributed to the reported event.The results of the query of similar incidents in the complaint handling database for this lot did not indicate a manufacturing issue.Based on the reviewed information, no product deficiency was identified.
