Methods for making a supported graft
First Claim

1. A method for forming a self-expanding stent-graft, comprising:
- coupling a shape memory member to a polymer cladding to form a polymer clad member;
disposing a length of the polymer clad member in an overlapping helical manner about a longitudinal axis;
joining and sealing adjacent overlapping regions of the polymer clad member to form a stent-graft;
manipulating the stent-graft from a first diameter to a second diameter smaller than the first diameter; and
loading the stent-graft into a restraining sheath at the second diameter, the restraining sheath preventing expansion of the stent-graft from the second diameter to the first diameter.
