Visual analysis was performed on the returned omnilink elite.The difficulty advancing was unable to be confirmed due to the condition of the returned unit.The reported stent damage was confirmed.Additionally, it was noted that the stent implant was dislodged from the balloon.The distal end of the stent implant was located on the distal end of the proximal balloon marker.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 complaints reported from this lot.The investigation determined the reported difficulties and noted dislodged stent were due to circumstances of the procedure.It is likely that the resistance encountered during advancement was due to interaction with the challenging anatomy.Additionally, it is likely that advancing against resistance and interaction with the challenging anatomy caused the stent damage, including the noted dislodged stent.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 moderately calcified, moderately tortuous, 75% stenosed lesion in the left common iliac artery.A 9x19mm omni elite vascular balloon expandable stent (bes) was advanced to the target lesion with resistance from the anatomy.Deployment was initiated at the target lesion; however, one of the stent struts was noted as mangled and deployment was aborted.The delivery system and partially deployed stent was removed as one unit without issue, and another omni elite bes was used to successfully complete the procedure.There was no adverse patient effect and no clinically significant delay in the procedure.No additional information was provided.The returned device analysis found that the stent was dislodged from the balloon.
