ABSTRACT:
A stent for reinforcing a vessel wall is disclosed. The stent is constructed from a single elongated wire. The wire is first bent into a series of tight bends. The wire is then rolled around a mandrel to create junctions of wire which are permanently adhered. 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.
