1. 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, and 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.
