An intraluminal prosthesis for strengthening a lumen. The prosthesis may includea tubular graft (50) comprising a hollow flexible body (20). A selfexpandingstent (19) may be coupled to the body (20) that provides enough outward radialforce to expand the body. The prosthesis also includes a tubular stent (17). Thetubular stent has a first diameter and a second expanded diameter. The tubularstent (17) is formable to the second diameter by application of an outwardly extendingforce from the interior of the tubular stent. The second diameter is at least equalto the interior diameter of the hollow flexible body (20).
