(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.(b)(4).The device was not returned for analysis.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.It should be noted that the xience xpedition everolimus eluting coronary stent system instructions for use states: applying excessive force to the delivery system can potentially result in loss or damage to the stent and/or delivery system components.The investigation determined that the reported shaft kink and shaft detachment appear to be related to the use error; however, the reported failure to advance appears to be related to the circumstances of the procedure.There is no indication of a product quality issue with respect to the design, manufacture or labeling of the device.

It was reported that the procedure was to treat a mildly tortuous and moderately calcified de novo distal right coronary artery that was 90% stenosed.An unspecified sion guide wire crossed the lesion, and pre-dilatation was done with a 2.5 x 20 mm trek balloon.Then, an attempt was made to cross a 3.0 x 38 mm xience xpedition stent; however, it failed to cross the lesion due to the anatomy.Additionally, the proximal shaft of the stent delivery catheter became kinked when force was used to advance the device in the mid right coronary artery.Therefore, the device was removed; however, the proximal shaft separated once it was outside the anatomy.A 3.0 x 33 mm xience xpedition stent was then implanted, and a 3.5 x 12 mm xience xpedition stent was also implanted to overlap the 3.0 x 33 mm xience xpedition stent to successfully complete the procedure.There was no clinically significant delay in the procedure and no adverse patient effects.No additional information was provided.
