    Abstract: The invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more links. A Y-shaped member comprised of a link and a U-shaped member has relief dimples formed in the curved portion of a valley to reduce localized stress and thereby reduce fatigue failure that can lead to link structure failure.

    Abstract: The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since the peaks that are adjacent the curved portion of the undulating link are shorter than other peaks in the same cylindrical ring to prevent overlap yet still achieve a very low profile, tightly crimped stent onto a catheter.

    Abstract: An expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. In one aspect, the stent includes a butterfly pattern to which connecting links are attached. In another aspect, the stent embodies a non-directional structure. One embodiment is a stent in which one or both ends are more flexible than the center portion. Also, the stent may have a non-uniform drug coating. Another embodiment relates to a stent having ends that are more radiopaque than the center portion.

    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.

    Abstract: An expandable stent for implantation in a body lumen, such as an artery, 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 radial strength of the stent is enhanced by selectively increasing the width of the crests by offsetting the center points of inner arcs relative to outer arcs.
