  • Patent number: 9707124
    Abstract: The invention describes methods and apparatus for creating permanent occlusion of body lumens such as the fallopian tubes. The methods and apparatus use non-surgical approaches to deliver permanent implants which create acute occlusion of desired body lumens which resolve to permanent occlusions of the lumens.

  • Patent number: 9492277
    Abstract: Soft body tissue structure can be remodeled by shortening the distance between first and second portions of that tissue structure. First and second anchor structures are respectively implanted in the first and second portions of the tissue structure. These anchor structures are linked by a linking structure, the length of which between the anchor structures can be shortened to pull the tissue structure portions toward one another. Each of the anchor structures may include two screw structures that are driven into the associated tissue structure portion transverse to the linking structure and with a spacer between the two screws. The entire prosthesis can be implanted percutaneously if desired. An illustrative use of the prosthesis is to shorten the annulus of a patient's mitral valve, with at least a portion of the prosthesis implanted in the patient's coronary sinus.

  • Patent number: 9101338
    Abstract: An implant structure for use in pulling two soft body tissue areas closer together in a patient (e.g., two points along or adjacent to the patient's mitral valve annulus) includes at least two tissue anchor structures that are respectively implantable into the two tissue areas. A tether structure links the two tissue anchors and can be shortened and held in that condition by a cinch structure. Bracing structures are used between the anchors and the tether to help keep the longitudinal axes of the anchors transverse to the tether axis even when the tether is under tension. The tether may be sheathed in a cushioning sleeve to help protect adjacent tissue from erosion by the tether.

  • Patent number: 8920434
    Abstract: Apparatus is provided that can be delivered through a catheter to a remote location in a patient's body. The apparatus may include a first structure that can be positioned in all dimensions in a controlled manner and stabilized in that desired position, a second structure that can then position a lumen axis at a desired angle relative to the first structure, and a third member that can pass through the lumen and approach and engage with force (e.g., penetrate) a desired location on the anatomy without compromising maintaining the desired position. The apparatus effectively separates the forces needed for positioning and the forces needed for tissue engagement (e.g., penetration).

  • Patent number: 8882787
    Abstract: A structure that can be used to provide an anchor in or adjacent to a patient's soft body tissue (rather than bone) includes an annular array of flexible members that extend between two axially spaced but aligned tubular members. The space between the tubular members can be selectively changed to affect the amount by which portions of the flexible members between the tubular member project radially outward relative to the tubular members. When the flexible members project radially out, the structure resists axial movement relative to adjacent tissue and therefore acts as an anchor. When the flexible members do not project radially out, they permit axial movement of the structure through adjacent tissue.

  • Patent number: 8632555
    Abstract: A medical graft connector for connecting an end of a tubular graft conduit to a side wall of a patient's existing tubular body conduit via an aperture in the side wall thereof has a first plurality of fingers configured to engage an interior surface of the side wall of the existing conduit. A second plurality of fingers is configured to engage an exterior surface of the side wall of the existing conduit. A third plurality of fingers is received in an interior lumen of the graft conduit, and a fourth plurality of fingers is configured to pierce the graft conduit. The connector is radially deformable between a first size and a second size.

  • Patent number: 8114123
    Abstract: Methods and apparatus are provided that gather a patient's body tissue and then secure the gathered tissue in a reduced area utilizing a securing structure. The securing structure mainly resides on one side of the tissue to minimize or eliminate both foreign material and the amount of manipulation or activity on the other side of the tissue. The securing device is matched to the desired amount of tissue manipulation to minimize the structure. The gathered and secured tissue can surround a septal defect to obstruct or close the defect itself.

  • Patent number: 8109947
    Abstract: Methods and apparatus for delivering and installing a new length of tubing between two sections of a patient's existing body organ tubing and at least partly outside of that existing structure. For example, the new length of tubing may be for the purpose of providing the patient with a coronary bypass. The new tubing may be an artificial graft, a natural graft (harvested elsewhere from the patient), or both. The new tubing is installed at the operative site primarily by providing at least one graft location with instrumentation inserted through the patient's existing tubular body organ structure. Assistance in installing the new tubing may be provided by minimally invasive surgical access openings in the patient's chest. The tubing may be delivered through the patient's existing tubular body structure or, alternatively, through the surgical access openings.

  • Patent number: 7361181
    Abstract: Apparatus and methods for creating anastomoses are provided. An incision tool for creating an incision having a controlled length in a side wall of a patient's body tissue conduit is provided. A delivery device for inserting a hollow annular connector into an incision in a side wall of a patient's body tissue conduit is provided. The delivery device may include first and second anvil structures around which the connector may be disposed. By moving the first anvil structure away from the second anvil structure, the connector may expand to a desired configuration (e.g., non-round) within the aperture. In one example, the connector may be inserted into the aperture to hold the aperture open prior to attachment of a graft conduit to the aperture, thereby allowing a physician to inspect the aperture and the surrounding tissue.

  • Patent number: 6866674
    Abstract: Methods and apparatus for making an anastomotic connection between a first conduit and a second conduit. A connector structure having a first end portion and a second end portion is positioned about a balloon catheter, which when pressurized, expands to a significant extent at the distal end thereof. The balloon enlarges the connector structure when positioned at the distal end portion of the balloon to create the anastomosis, and at the same time reduces the axial length of the connector, thereby compressing the first conduit to the second conduit, creating a hemodynamic seal and a firm attachment of the two conduits. After enlargement, the connector structure remains in place and adds structure to the anastomosis. During introduction, the second end portion of the connector is covered by a nosecone assembly to prevent trauma to the second conduit while the apparatus is being introduced.

  • Publication number: 20040243154
    Abstract: Connector structures are provided for attaching elongated flexible tubular grafts to the body organ tubing of a patient. The connector structures are formed from wire. A first set of connector wires may be disposed around the periphery of one end of an elongated flexible tubular graft. A second set can be disposed around the periphery of the elongated flexible tubular graft spaced sufficiently from the first set of connector wires to define a gap. The portion of body organ tubing to which the elongated flexible tubular graft is to be attached is received in the gap and engaged by the first and second sets of connector wires. The wires may be formed in the shape of loops. If desired, hooks may be provided on the ends of the wires. The wires may be curved to accommodate attachment of the graft to tubular body organ tubing. The wires may also be formed in annular shapes. The connector structures may be formed as stand-alone ring-shaped connectors.

  • Publication number: 20040186566
    Abstract: A patient's soft body tissue can be remodelled by implanting first and second anchor structures in the tissue at respective first and second spaced locations. A linking structure between the anchor structures is then operated to change the distance between the first and second anchor structures. Examples of use are repair of a patient's mitral and/or tricuspid valve(s) and/or remodeling of a patient's left ventricle.
