A graft tube is percutaneously placed inside the lumen of a vessel and attached to the lumen wall by loops of suture material. The plurality of short sutures are made in the shape of a loop with a sharp and a blunt end then forced into a plurality of first tunnels located in sections of circular cuffs that are attached to graft tube ends. The short sutures are pushed out the first tunnel by push rods and curve back to their original shape through the adjacent lumen wall and into a plurality of second tunnels where the short sutures are lodged. |
