a resilient tubular graft is delivered into place within a body passage by elongating the graft to reduce its diameter and then directing the graft to the desired position while in the elongated condition . the graft is carried into position by a pair of elongate members mounted for longitudinal movement relative to one other . flexible lines secure opposite ends of the graft to the respective elongate members whereby relative longitudinal movement of the members functions to elongate the graft and reduce its diameter . the lines extend around the graft to impart radial compression thereto simultaneously with elongation of the graft . upon placement of the graft at the desired location within a body passage , the lines are released to permit the graft to expand into engagement with the passage . barbs on the graft provide for secure engagement of the graft with a body passage .
