摘要：
A method for preparing a stent-graft for intraluminal delivery, including positioning an expanded polytetrafluoroethylene (ePTFE) substrate over a support mandrel, coupling a shape memory member to a polymer cladding to form a polymer clad member, winding the polymer clad member in an overlapping helical manner onto a surface of the ePTFE substrate, joining and sealing adjacent overlapping regions of the polymer clad member together and to the surface of the ePTFE substrate to form a stent-graft, manipulating the stent-graft from a larger first diameter to a smaller second diameter, and loading the stent-graft into a restraining sheath at the smaller second diameter.
