An intraluminal prosthesis for strengthening a lumen. The prosthesis may include a tubular graft (50) comprising a hollow flexible body (20). A self-expanding stent (19) may be coupled to the body (20) that provides enough outward radial force to expand the body. The prosthesis also includes a tubular stent (17). The tubular stent has a first diameter and a second expanded diameter. The tubular stent (17) is formable to the second diameter by application of an outwardly extending force from the interior of the tubular stent. The second diameter is at least equal to the interior diameter of the hollow flexible body (20).
