Abstract: An expandable stent for implantation in a body lumen, such as an artery, is disclosed. The stent consists of a plurality of radially expandable cylindrical rings generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting links placed so that the stent is flexible in the longitudinal direction. The link pattern is optimized to reduce strain on the links and enhance longitudinal flexibility and security of the stent. The stent includes a distal end ring and a proximal end ring that have a length that is shorter than the length of the body rings.
