ABSTRACT:
A stent for reinforcing a vessel wall is disclosed. The stent is constructed from two elongated wires which are each bent into a series of tight bends. The two wires are permanently adhered at a first interconnection junction. The two wires are then wrapped around a mandrel repeatedly forming two opposing series of interconnections. The two wires are then permanently adhered at a second interconnection junction after a desired stent length is obtained. The completed stent forms a cylindrical form which can be expanded from an initial diameter to a larger implanted diameter by application of a radially outward force from a balloon catheter or the like.
