ABSTRACT:
A stent for reinforcing a vessel wall is constructed from a single elongated wire. The wire is first bent into a series of tight bends. The wire is then further bent into a sequence of loops that are connected by half hitch junctions and interconnections which are either aligned or spiral around a circumference of the stent. The completed stent forms a cylindrical form which can be expanded from a initial diameter to a larger implanted diameter by application of a radially outward force from a balloon catheter or the like.
