High expansion ratio stent
First Claim
1. A stent segment comprising members having a rectangular cross-sectional profile with edge sides having a dimension less than face surfaces, each member being comprised of two curved portions having opposite directions of curvature, a transition segment connecting said two curved portions, adjacent members joined on their face surfaces by having a first end of each member joined to a second end of an adjacent member to form said stent segment having an outer surface, each member lying in said stent segment outer surface, said face surfaces of each member being oriented generally perpendicular to said stent segment outer surface.
