Abstract:
A self-expanding stent device comprising:a small diameter skeletal tubular member having a thin wall and having a proximal end and a distal end; said wall of said tubular member comprised of a plurality of cells which are formed by a plurality of generally undulating members and a plurality of single strand, unbranched struts; said struts interconnecting the undulating members, in which said undulating members are generally parallel with the longitudinal axis of said tubular member and are generally parallel to each other; each undulating member has a positive peak and a negative peak; each strut has a proximal end and a distal end; a first undulating member and said struts within a first row have a repeating pattern in which the proximal ends of each of said struts are attached to negative peaks of said undulating member and the distal ends of each of said struts of said first row are attached to positive peaks of a second, adjacent undulating member, and the proximal ends of an adjacent row of struts are attached to positive peaks of said first undulating member; and the distal ends of each of said struts of said adjacent row are attached to negative peaks of a third, adjacent undulating member, wherein said skeletal tubular member includes a proximal leg; said proximal leg extends generally parallel to the longitudinal axis of said tubular member and is attached to the proximal end of said skeletal tubular member; and the proximal leg includes an attachment flange.
