Abstract
In accordance with the present invention, there is provided a stent-graft for insertion into target site within a vessel of a patient. The graft has a crimped state for delivery to the target site, and an expanded state for implantation therein. The graft has a self-expanding outer stent, which is a tubular member made from an elastic material. The graft further includes a tubular flexible porous graft member extending along the interior of the outer stent. The graft member has front and back ends which are folded over and bonded to the front and back ends of the outer stent to form cuffs. In addition, the stent-graft has a self-expanding inner stent which also is a tubular member made from an elastic material. The inner stent is disposed within the interior of the graft member such that the inner stent, the graft member and the outer stent are all abutting.
