Abstract
Abstract In accordance with the present invention, there is provided a stent for implantation into a vessel of a patient. The stent has at least two plastically deformable and expandable tubular graft members for expansion within a vessel. Each of the graft member has a first end, a second end, a wall section disposed therebetween and a lumen extending therethrough. The stent further includes at least one articulation connecting the first end of one of the graft members with the second end of the other graft member. Wherein the articulation is made from a superelastic material.
