A stent-graft (10) is provided which includes a smooth continuous inside surface for efficient fluid flow therethorugh. The stent-graft (10) can be implanted intraluminally by radially expanding the stent-graft adjacent an area within the body lumen to be treated, or can be implanted utilizing direct surgical techniques. A cylindrical support structure (18) is preferably provided which is at least partially embedded along with portions of the film. The cylindrical support structure can facilitate radial expansion and provide additional structural strength to the stent-graft (10). A woven fabric support structure (162) can also be embedded within the film of solid material forming the stent-graft (170) to provide additional support to the stent-graft (170) and allow suturing of the stent-graft (170) to walls of the body lumen. Various different geometric configurations can be provided for the stent-graft.
