A self-expanding tubular stent comprises a plurality of stent segments. Each stent segment is formed of an elongate ribbon having portions cut therefrom to form a wave-like undulating pattern, opposed edges of which are attached to one another so as to form a generally cylindrical configuration. A disclosed method effects formation of such an expandable tubular stent by first providing an elongate flat ribbon of biocompatible stent material and selectively removing portions of such material to form an undulating wave-like pattern along the length of the ribbon. The ribbon is then coiled into a generally cylindrical configuration and opposed ends of the ribbon are secured to one another to form a generally cylindrical and expandable spiral stent section. After forming a plurality of such stent sections, the stent sections are arranged in longitudinal succession and interconnected so as to form an elongated stent configuration.
