Summary:The invention essentially relates to a spiral stent forming device as well as to a method of making it. A stent having a first filamentary element () with a proximal end portion and a distal end portion, and being spirally coiled in at least its central portion, and a second filamentary element () spirally coiled along its central portion and overlapping the first filamentary element to form a double helix is disclosed along with a method for forming such a stent. At least one end portion of the first filamentary element is ring-shaped to provide increased radial support at that end of the stent.
