  • Patent number: 11103251
    Abstract: The present invention relates to an in vivo indwelling member which has a shape complicatedly curved in various directions and can easily spread inside an aneurysm, while adhering to an inner wall of the aneurysm to prevent falling off therefrom, improving an indwelling density, and maintaining good operability. Shapes of two or more three-dimensional portions (middle solid 4A, large solid 4B) are provided in a primary coil 11. Each three-dimensional portion is formed by continuously providing at least four curved parts (51a to 51e/52a to 52f) over four planes. Normal directions of the four planes each have a relationship perpendicular to a predetermined common axis (a1/a2) direction. Each of the at least four curved parts (51a to 51e/52a to 52f) is formed on any of the respective planes of a quadrangular virtual cylindrical body as seen from the common axis (a1/a2) surrounded by the four planes.

  • Patent number: 11083480
    Abstract: A gripping mechanism includes: two gripping pieces pivoted relative to each other about a pivot axis; a base supporting at least one of the gripping pieces; a pulley rotatably supported about a rotation axis parallel to the pivot axis; a wire wound around the pulley, causing tensile forces that move the rotation axis in one direction to act, and transmitting a pressing force; and a force-receiving portion receiving the pressing force. The pulley is disposed so that a resultant force of the tensile forces of the wire acting on the rotation axis generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be closed. The force-receiving portion is disposed so that the pressing force applied from the wire generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be opened.

  • Patent number: 11076973
    Abstract: A transorally implantable intragastric helical prosthesis for treating obesity. The helical prosthesis has a primary lumen having a balloon element therein, and a secondary lumen having a spring wire element therein. The prosthesis also includes an end fitting. When deployed into the stomach of a patient, the prosthesis spontaneously reverts from a linear pre-deployment configuration to a helical post-deployment configuration by the biasing action of the spring wire element. Upon inflation of the elongated balloon element, the prosthesis unwinds, dynamically engaging and stretching the stomach wall, reducing the intragastric space, and slowing down gastric emptying, thus promoting a feeling of satiety, which may result in weight loss.

  • Patent number: 11052170
    Abstract: The invention relates to a device for treating blood flow in an internal wound, including a handling member connected to a series of successively narrower tubes, each tube including a liquid-expandable article. The tubes can be pivotably connected to each other, allowing the tubes to conform to the contours of the wound, or fixed together. The tubes can be encased in a liquid-soluble layer that keeps the liquid-expandable article sequestered from liquids. The stepwise-tapering profile of the device allows for its insertion into the internal wound with little or no resistance until fully seated. Upon encountering liquids within the wound, the liquid-soluble layer can dissolve to expose the liquid-expandable article. When exposed to the wound liquids, the liquid-expandable element can expand in volume, providing compressive pressure against internal wound surfaces and minimizing blood loss. The tubes and the liquid-expandable element can include therapeutic agents for treating the wound.
