Claims20
A stent-graft comprising:
- a first stent, the first stent comprising a first stent wire configured in a stent wire pattern;
- graft material, the graft material having a substantially tubular first graft shape with an inner surface and an outer surface and a lumen extending therethrough;
- and
- a continuous machine stitch, the continuous machine stitch being stitched into the graft material according to the stent wire pattern and comprising a plurality of loop points, the plurality of loop points being disposed on the outer surface of the substantially tubular first graft shape wherein the plurality of loop points substantially outline the stent wire pattern;
- and
- wherein the first stent wire is attached to the graft material at the plurality of loop points on the outer surface of the substantially tubular first graft shape.
