    摘要: An expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen is provided. An intravascular stent is formed by cylindrical rings connected by links. The rings have peaks and valleys from which extend straight and nonlinear bar arms, forming a figure-eight. An elemental unit is defined with straight and nonlinear bar arms, and elemental units on adjacent rings are mirror images of one another. The links have one end connected at a peak of one ring and the other end connected to a central portion of a nonlinear bar arm. Alternating rows of the links consist of nonlinear links.

    摘要: A hybrid stent is formed which exhibits both high flexibility and high radial strength. The expandable hybrid stent for implantation in a body lumen, such as a coronary artery, consists of radially expandable cylindrical rings generally aligned on a common longitudinal axis and interconnected by one or more links. In one embodiment, a dip-coated covered stent is formed by encapsulating cylindrical rings within a polymer material. In other embodiments, at least some of the rings and links are formed of a polymer material which provides longitudinal and flexural flexibility to the stent. These polymer rings and links are alternated with metallic rings and links in various configurations to attain sufficient column strength along with the requisite flexibility in holding open the target site within the body lumen. Alternatively, a laminated, linkless hybrid stent is formed by encapsulating cylindrical rings within a polymer tube.

    摘要: The present invention is directed to an expandable polymer link hybrid stent for implantation in a body lumen, such as a coronary artery along with a method of making the stent. The stent generally includes a series of metallic cylindrical rings longitudinally aligned on a common axis of the stent and interconnected by a series of polymeric links. The polymer links are formed by applying polymer layers between the rings and laser ablating the excess material. The polymeric material forming the polymeric links, provides longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the cylindrical rings along the longitudinal axis. The metallic material forming the rings provides the necessary radial stiffness.

    摘要: An expandable hybrid stent having metallic rings and polymer interconnecting links is disclosed. One embodiment of the stent has radially expandable cylindrical rings generally aligned on a common axis and interconnected by one or more polymer links that attach at formations formed in the rings. The polymer links have sufficient column strength to keep the rings from collapsing together axially. The formations may be holes, notches, grooves, channels, dovetails, or the like and the links wrap around, pass through, or lie on the formations. The junction of the link and ring at the formation is then melted and allowed to solidify. Alternatively, beads may be formed on either side of where the link passes through a hole in the ring thus securing the ring to the link.
