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 interconnected, non-inverted horizontal and inverted horizontal S-shaped members; said interconnected S-shaped members are generally parallel with the longitudinal axis of said tubular member; each interconnected S-shaped member has a proximal end, a distal end, a proximal intermediate section, and a distal intermediate section; and, said interconnected S-shaped members having a repeating pattern comprised of a configuration in which said proximal end of each non-inverted horizontal S-shaped member is attached to said distal intermediate section of an adjacent inverted horizontal S-shaped member, said distal end of each non-inverted horizontal S-shaped member is attached to said proximal intermediate section of another adjacent inverted horizontal S-shaped member, said proximal end of each inverted horizontal S-shaped member is attached to said distal intermediate section of an adjacent non-inverted horizontal S-shaped member, and said distal end of each inverted horizontal S-shaped member is attached to said proximal intermediate section of another adjacent non-inverted horizontal S-shaped member.
