  • Patent number: 9907639
    Abstract: The present invention provides apparatus and methods for treating a vascular condition by restoring patency to a vessel while reducing the likelihood that emboli become dislodged into the bloodstream. In a first embodiment, the apparatus comprises a graft having proximal and distal regions, a first support member attached to the distal region of the graft, and a second support member attached to the proximal region of the graft. The first and second support members may comprise first and second stents, respectively. The first stent is deployed distal to a vascular condition, and the second stent is deployed proximal to a vascular condition, such that the graft spans the length of the vascular condition to entrap emboli during treatment of the vascular condition. In an alternative embodiment, the graft is adapted to be everted to form a pocket adapted to entrap emboli dislodged during treatment of the vascular condition.

  • Patent number: 9801624
    Abstract: A medical instrument, such as a surgical device for manipulating and placing a tissue suture and methods of using the same is disclosed. The device comprises a handle, a hollow shaft removably coupled to the handle assembly and a stylet extending within the hollow shaft and longitudinally slideable therein. Preferably, the stylet is not rotationally moveable relative to the shaft. The stylet may be moved between a first position wherein a grasping member formed on the stylet is retracted into a distal end portion of the shaft and a second position wherein the grasping member extends distally beyond the distal end portion of the shaft. Distal movement of an actuation member on the handle correspondingly moves the stylet to the extended position and movement of the actuation member to a proximal position on the handle correspondingly moves the stylet to the retracted position. Lateral movement of the actuation member on the handle does not impart rotational movement of the stylet relative to the shaft.

  • Patent number: 9623206
    Abstract: A catheter having a selectively variable degree of flexibility includes an elongate tubular outer member and an elongate tubular inner member disposed within the outer member. The catheter further includes a cavity disposed in between the outer and inner members. A tubular braid of filaments may be disposed within the cavity. The outer and inner members are movable relative to each other along intermediate portions thereof when in a first configuration, and are not movable relative to each other when in a second configuration. When the inner and outer members are in the first configuration, the tubular braid of filaments is movably disposed relative to at least one of the outer member and the inner member. When the inner and outer members are in the second configuration, the inner and outer members clamp the tubular braid of filaments in a fixed position relative to the inner and outer members.
