It was reported that during a procedure of the moderately tortuous, mildly calcified, 80% stenosed, de novo, mid right femoral artery, 10 cm lesion with normal outflow, a 6.0 x 120 absolute pro stent was implanted without issue.Post dilatation with a 5.0 x 120 mm amada 35 balloon could not be performed as the balloon could not be advanced properly into the stent.The balloon was removed and angiography performed, noting that the stent was fractured.The wire was changed out and post-dilatation of the stent was performed with an unspecified balloon first and then with the same 5.0 x 120 mm armada 35 balloon, without issue.The final angiographic result was reported as nice.No additional intervention was performed.There was no additional information provided.

(b)(4).The delivery system was not returned for analysis.A review of the lot history record revealed no non-conformances that would have contributed to the reported event.A query of the complaint handling database revealed no other similar incidents reported from this lot.A cine was received and reviewed by an abbott vascular clinical specialist, who noted that the stent struts were misaligned with a discontinuous pattern.The investigation was unable to determine a cause for the reported difficulties.There is no indication of a product quality issue with respect to the design, manufacture or labeling of the device.
