    Abstract: The present invention relates to covered endoprosthetic devices. Covered endoprosthetic devices comprise an endoprosthesis and a sheath. The sheath comprises a central portion and outer portions, wherein the central portion preferentially restricts or causes a restriction of blood flow. Blood flow can be reduced by the central portion of the sheath by varying the permeability of the sheath or by having projections on the sheath that slow blood flow. Permeability may be provided by perforations or holes in the material of the sheath or by varying the polymer structure that makes up the sheath itself. The outer portions of the sheath do not substantially reduce blood flow. Methods of using sheath-covered endoprosthetic devices of the invention to treat aneurysms, especially aneurysms in proximity to small perforator vessels or arteries, are also encompassed.

  • Patent number: 8668730
    Abstract: A vascular device comprising a plurality of vessel engaging members and a valve. The device is movable from a collapsed insertion position having a first diameter to a second expanded position having a second diameter larger than the first diameter. The plurality of vessel engaging members extend outwardly from the device for securely engaging the internal wall of a vessel upon expansion of the device to the second expanded position, wherein the vessel engaging members pull the internal wall of the vessel radially inwardly upon movement of the device from the second expanded position toward a first expanded position having a third diameter greater than the first diameter and less than the second diameter. In the first expanded position the valve is movable between an open position to allow blood flow therethrough to a closed position to prevent blood flow.

  • Publication number: 20140046427
    Abstract: The present disclosure includes a securing device comprising one or more barbs. A barb may comprise a depth stop, which may itself comprise an apex portion coupled to a trough portion. A barb may be constructed, in various embodiments, from a length of shape memory wire. Thus, during deployment, a barb may spring away from a medical device to which the barb is coupled such that the barb makes contact with and punctures, to a limited depth, a body lumen wall. A barb may not, however, fully puncture a body lumen wall. Rather, a depth stop may limit a puncture depth to a depth that does not endanger and/or subject tissue surrounding or external to the lumen wall to damage and/or bleeding or leakage from within the lumen. In various embodiments, a pair of barbs may be coupled to from an integral two pronged barb.

  • Patent number: 8632488
    Abstract: An implant for treating medical disorders includes a first chamber having a flexible outer layer that surrounds a flexible inner layer, a second chamber in communication with the first chamber, and a fluid transfer assembly adapted for transferring fluid between the second chamber and the first chamber for selectively modifying the rigidity of the first chamber. The implant includes at least one restraining element in contact with the flexible outer and inner layers for at least partially restricting volume expansion of the first chamber as the fluid is transferred into the first chamber. The first chamber is adapted to become more rigid as the fluid is transferred into the first chamber and more flexible as the fluid is removed from the first chamber. The first chamber is implantable within the soft tissue of a patient such as a tongue, soft palate, pharyngeal wall, urinary tract, rectum, trachea, or stomach.

  • Patent number: 8591569
    Abstract: Disclosed herein is a stent for prostatic urethra expansion which does not generate bladder stones, is removable without causing injury on a urethra, and does not generate atrophy of a prostatic urethra even after removal. The stent for prostatic urethra expansion include a stent unit including a cylindrical body with space parts formed by knotting or crossing shape memory alloy wires and bending terminals formed at both ends of the cylindrical body, a pair of hook wires passing through the space parts and knotted to the shape memory alloy wires, both ends thereof being wound on the bending terminals and then being bent upwardly to produce hooks, and a pair of hanging strings arranged in opposite directions to form a hanging knot. The stent for prostatic urethra expansion does not move into the bladder, and expands and maintains a lumen of the stenosed prostatic urethra, thereby reducing post-operative recovery time.

    Abstract: A stent graft adaptor has an outer graft tube and an inner graft tube with the inner graft tube substantially concentric with and within the outer graft tube. A joining member extends between the inner tube and the outer tube. The s joining member can be a continuous fold of graft material extending from a proximal end of the outer tube to a proximal end of the inner tube. The inner tube has at least one self expanding stent on an outer surface thereof and the outer graft tube has at least one self expanding stent on an inner surface. The outer surface of the outer tube provides a sealing surface to engage against the wall of a vessel and the inner tube provides a sealing surface to engage with a corresponding sealing surface of a stent graft deployed through it. The outer sealing surface can include barbs.

  • Patent number: 8556956
    Abstract: A removable device such as a stent-graft, intended for applications where it may be desirable to remove the device at some time following implantation. The stent-graft of the present invention includes a helically-wound stent component provided with a covering of graft material. It is removable by gripping an end of the helically-wound stent component with a retrieval device and applying tension to the stent component in the direction in which it is intended to be withdrawn from the site of implantation. The use of such a retrieval device allows the stent-graft to be removed remotely, such as via a catheter inserted into the body at a different location from the implantation site. The design of the stent-graft is such that the stent component is extended axially while the adjacent portion of the graft separates between windings of the stent component.

  • Patent number: 8465436
    Abstract: An implant centering system includes a sensor connected to a hollow cylindrical anchor via at least two struts. The hollow cylindrical anchor is transformable between a radially compressed configuration for delivery and a radially expanded configuration for lodging against a vessel wall. The struts longitudinally relocate the sensor between a first position in which the sensor is longitudinally spaced apart from the radially compressed anchor, and a second position in which the sensor is at least partially within a lumen of the radially expanded anchor and radially centered within vessel. In one embodiment, the struts are heat-set into a curved configuration and an externally applied force longitudinally relocates the sensor until the struts lock over center into their heat-set configuration. In another embodiment, radial expansion of the anchor longitudinally relocates the sensor without an externally applied force.
