  • Patent number: 7763062
    Abstract: A method and apparatus of treating an abdominal aortic aneurysm in a patient includes the steps of providing a deployable tubular graft of length to extend across the aneurysm. The graft is inserted endovascularly through an artery communicating with the aorta to a site within the aorta whereby an insertion end of the graft is positioned adjacent a non-dilated region of the aorta. The graft is deployed such that the insertion end of the graft is placed against an interior wall of the non-dilated region of the aorta. The graft is held from within the graft against the interior walls of the aorta and while being held, sutures are introduced laparoscopically through a wall of the aorta to the exterior of the graft whereby the graft is sutured to the inner walls of the aorta and the graft.

  • Publication number: 20080051736
    Abstract: According to an aspect of the invention, an indwelling catheter is provided which comprises a catheter shaft. The catheter either comprises a light source or is adapted to receive light from a light source, and is configured such that light is transmitted from the light source into the catheter shaft. Moreover, the catheter shaft is formed of a polymeric material that transmits a quantity of light from the light source that is effective to inactivate microorganisms on a surface of the catheter shaft upon activation of the light source. For example, the light may inactivate the microorganisms directly or in conjunction with a photosensitizer. According to another aspect of the invention, a sterilization method is provided, which comprises activating the light source while the catheter is inserted in a subject.

  • Patent number: 7320703
    Abstract: A graft system for intraluminal delivery in a vessel in need of repair comprising a graft, anchoring means, and a strippable sheath around at least part of the graft. A preferred anchoring means is a balloon-expandable stent. Also included in the invention is a method of using the device to treat a body lumen. The strippable sheath is removable by pulling on a drawstring to remove it which permits expansion of the graft. The positioning of the device may then be adjusted prior to stent dilation. A preferred embodiment of the invention includes a bifurcated graft system for intraluminal delivery in an aortic aneurysm comprising a bifurcated graft having a distal region and two legs, an expandable stent disposed in part of the distal region, and a strippable crocheted sheath around the distal region and one of the two legs. The strippable crocheted sheath is removable by untying it to permit expansion of the graft after initial placement within the aneurysm.

  • Patent number: 7267686
    Abstract: A prosthetic valve for implantation within a fluid conducting lumen within a body includes an elongate generally cylindrical radially collapsible valve body scaffold defining a fluid passageway therethrough for retentive positioning within the lumen. A radially collapsible leaf valve member is supported by the scaffold includes a number of valve leafs deflectable between a closed position restricting fluid flow through the passageway and an open position permitting fluid flow through the passageway. The leaf valve member includes an interior leaf valve frame defining a valve leaf aperture which is sealed by a fluid impermeable non-thrombogenic lining to prevent fluid flow therethrough.
