Stitch wire routing and delivery system

A method for controlling a stent graft, the method comprising:

• disposing a transitional stitching on a tube of a stent graft, the transitional stitching comprising more than one stitches, each stitch of the transitional stitching comprising a stitch loop, wherein the transitional stitching comprises a distal portion stitching, and a proximal portion stitching;
• disposing a portion of each stitch loop outside the tube and passing a string through the stitch loop outside the tube, the string comprising a distal portion, a middle portion, and a proximal portion, wherein the method comprises:
• passing the distal portion of the string through stitch loops of the distal portion stitching,
• disposing the middle portion of the string circumferentially around the tube, and
• passing the proximal portion of the string through stitch loops of the proximal portion stitching;
• and
• placing, upon the string, tension larger than a tension threshold so that the stent graft is compressed.
