A radially expandable stent is useful for holding a passageway open by placing the stent into a lumen. The stent includes a cylindrical frame formed by a plurality of unit structures. Each unit structure is of a closed zig-zag configuration including an endless series of straight sections joined by bends. The plurality of unit structures are arranged end to end to form the frame. A plurality of connecting members connect the unit structures together. The outer surface of the frame is wrapped with mesh, which is preferably coated with silicone rubber.
A self-expanding stent comprising: a cylindrical main frame of a first diameter and comprising a plurality of unit structures, each unit structure formed in an endless zig-zag configuration; a plurality of connecting members for connecting the unit structures to one another while allowing expansion
A self-expanding stent comprising: a cylindrical main frame of a first diameter and comprising a plurality of unit structures, each unit structure formed in an endless zig-zag configuration; a plurality of connecting members for connecting the unit structures to one another while allowing expansion and contraction of the main frame; an anti-migration frame fastened to the main frame for preventing the stent from migrating, the anti-migration frame having the same structure as the main frame and a second diameter larger than the first diameter of the main frame; and a mesh wrapped around an outer surface formed by the main frame and the anti-migration frame, wherein the stent further comprises a coating of silicone rubber over the mesh.
