Abstract
The present invention includes: an expandable, tubular shaped prosthesis having first and second ends and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members; and a catheter, having an expandable, inflatable portion associated therewith and including means for mounting and retaining the expandable tubular shaped prosthesis on the expandable, inflatable portion, whereby upon inflation of the expandable, inflatable portion of the catheter, the prosthesis is formed radially outwardly into contact with the body passageway. The articulation in the form of a rounded wire frame loop connects similar stent bodies. Also, rounded open connectors and shortened cells in the stent allow for greater flexibility.
