  • Patent number: 8961583
    Abstract: This invention relates generally to an expandable intraluminal medical device for use within a body passageway or duct, and more particularly to an optimized stent having flexible links that minimize foreshortening during stent deployment. In one embodiment of the present invention the intraluminal prosthetic device includes a first hoop section, a second hoop section, and one or more flex members attached between the first and the second hoop section. Each flex member comprises two generally longitudinally extending curved segments connected by a circumferentially undulating segment.

  • Patent number: 8221489
    Abstract: A device and method for treating a body conduit/lumen having an undesired reduced diameter include delivering an expandable stent in a contracted configuration to a target location. The stent has small cells that form an open tight mesh providing the effective capture of small particles such as thrombi. Preferably, the tight mesh is combined with structure that permits creation of large side openings to accommodate lumen branches.

  • Patent number: 8080052
    Abstract: The present invention envisions an improved flexible connecting link used in conjunction with in-phase and half-phase circumferential sets of strut members. By increasing the total length and diagonality of the undulating connecting links, the present invention is a stent that provides increased flexibility during delivery and enhanced conformability to the shape of a curved artery when the stent is deployed into a curved vessel such as a tortuous coronary artery.

  • Patent number: 7867176
    Abstract: A guidewire navigable through body vessels of a human subject for delivery of a catheter or the like is provided. The guidewire has a tube which receives a corewire that protrudes beyond a distal portion of the tube. The protruding portion of the corewire is surrounded by a spring and shapeable into a curve or arc. The cross-sectional shape of the spring may be varied in order to promote bending flexibility and curvature or to favor curvature of a chosen type. The corewire is axially movable with respect to the tube, which compresses or stretches the spring to change the stiffness of the spring. The tube has a proximal portion comprised of a relatively rigid material, such as stainless steel, while a distal portion is comprised of a more flexible material, such as a nitinol.

  • Patent number: 7842077
    Abstract: A stent with axial flexibility, in a preferred embodiment, has a longitudinal axis and comprises a plurality of longitudinally disposed bands, wherein each band defines a generally continuous wave along a line segment parallel to the longitudinal axis. A plurality of links maintains the bands in a tubular structure. In a further embodiment of the invention, each longitudinally disposed band of the stent is connected, at a plurality of periodic locations, by a short circumferential link to an adjacent band. Further, a pair of bifurcated stents is disclosed.

  • Patent number: 7758632
    Abstract: The present invention relates to a medical device, and in particular, to a stent-based valve. The valve includes a radially expandable structural frame comprising a proximal and distal anchors formed from a lattice of interconnected elements, and having a substantially cylindrical configuration with first and second open ends and a longitudinal axis extending there between. One or more cantilevered valve struts are attached directly or indirectly to the proximal anchor. The stent based valve also comprises one or more connecting members attached between the proximal and distal anchors. A biocompatible valve assembly is coaxially disposed and attached to the proximal anchor and extends in the longitudinal direction along the one or more connecting members.

  • Patent number: 7594927
    Abstract: A stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an “N”), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent. Finally, a new method is disclosed for making stents.

  • Patent number: 7481778
    Abstract: A steerable guidewire having a deflectable distal tip which comprises a longitudinal hypotube and an interlocking spring coil attached to the distal end of the hypotube and also includes a longitudinally movable deflection member which is attached to the distal end of the spring coil and a tip retaining ribbon which extends from the distal end of the hypotube to the distal end of the spring coil for providing very precise deflection of the distal tip. The distal end of the deflection member has “skived,” or tapered, sides to enhance the flexibility of the guidewire.

  • Publication number: 20080058764
    Abstract: Balloon catheter designs are disclosed where the as-molded distal tip portion assumes a generally non-linear configuration. The non-linear tip configuration minimizes the gap between the wall of the catheter and the guidewire when the catheter passes over the guidewire when threaded through tortuous portions of the vasculature. The edge of the tip portion may be bias-cut angled with respect to the axis of the catheter to further reduce the gap. The disclosure also describes methods to use the catheter designs.
