It was reported that the procedure was to treat a 70% stenosed de novo lesion in the iliac artery with mild calcification and mild tortuosity.An attempt was made to advance the 9.0x29mm otw omni elite stent delivery system (sds); however, it could not be advanced through the 6f sheath.A non-abbott stent was used to complete the procedure.There was no adverse patient effect and no clinically significant delay reported in the procedure.Returned device analysis found the stent implant was dislocated on the balloon, damaged stent struts, and the distal shaft was stretched.Follow-up with the account confirmed that this damage occurred during removal of the sds from the 6f sheath.No additional information was provided.
