Abstract
A method for forming a self-expanding stent-graft, including 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.
