    摘要: A stent has a tubular body with longitudinal struts interconnected by multi-bar linkages. The linkages comprise a pair of circumferential extending links, a pair of axial links and a pair of spaced hinges located between the circumferential links and the axial links. The struts inhibit foreshortening of the body and relative rotation between the links in the linkages, permitting radial expansion. The links are plastically deformed as they are expanded to maintain the expanded diameter.
