Abstract
A stent has a tubular body with longitudinal struts interconnected by multi-bar linkages. The struts inhibit foreshortening of the body and relative rotation between the links in the linkages permits radial expansion. The links are plastically deformed as they are expanded to maintain the expanded diameter.
