  • Patent number: 10448979
    Abstract: Described is a new bone healing method and class of bone fixation implants that change shape once implanted so as to minimize non-healing and speed the bone healing process. The bone fixation method involves shape changing implants that continuously hold the bones in apposition so that a gap does not form. Gaps in time allow non-bony tissue to infiltrate and stop healing. Furthermore, the implants actively compress bone to increase bone mass and strength. Bone cell pressure due to compression and electrical current flow due to bone deformation act to stimulate healing. The new implant designs also provide a scaffolding to conduct bone through the implant and across the healing bone interface. The methods and designs are applicable to but not limited to use for bone screws, plates, staples, rods, cylinders and external fixation devices.

    Abstract: A method for closing an opening in a wall of a body lumen wherein an elongate member is advanced into the body lumen and a distal portion of an obturator is positioned distally beyond the distal end of the elongate member within the body lumen and in which one or more expandable elements on the distal portion of the obturator are expanded. The obturator is then withdrawn until the expandable elements contact the wall of the body lumen and a clip having tines is advanced over the elongate member until the tines penetrate the wall of the body lumen. The tines and the expandable elements are offset from one another. The elongate member is withdrawn from the body lumen and the clip substantially closes the opening in the body lumen.

  • Patent number: 6916327
    Abstract: A surgical staple for use in creating an everted anastomosis of at least two anatomical structures includes a bendable staple body. At least two evening elements protrude from the staple body. Spacing elements and a penetrating element also are provided. In use, the evening elements and spacing elements are apposed, and inner layers of the anatomical structures are held together to form an evened anastomosis. The evening platforms are disposed on an outer radius of the closed staple, and the penetrating element is disposed on a different, inner radius, to ensure that the penetrating element is excluded from the lumen of the anastomosis. Embodiments of the invention substantially ensure intima-to-intima approximation completely circumferentially at the anastomotic site, with no portion of cut tissue edges, suture or staple exposed to the lumen of the anastomosis. Cut tissue edges, as well as the staple, are completely extra-lumenal. Related methods provide similar advantages.

  • Patent number: 6913607
    Abstract: A self-closing fastener is described that comprises a clip passable through a tissue opening. The fastener is adapted for holding by a mechanism in an open configuration for passing through the tissue, followed by releasing the fastener from the holding mechanism, allowing the clip to remain in the tissue in a shape that can clip two or more locations on the tissue. The fastener and delivery devices are particularly useful for tissue approximation, such as anastomosis. When used for anastomosis, the inventive clips provide intima-to-intima contact with a minimal amount of intraluminal exposure.

  • Publication number: 20040260340
    Abstract: A tissue approximation device and method, particularly in the mid-face region, are provided. The device is an implantable, biodegradable construct that has attachment points emanating from a supportive backing. The device also has an extension member or leash which extends from the backing which is configured to receive a tissue or bone attachment device at one of a plurality of selectable locations along the elongated member, for example via engagement holes extending in a line away from the backing. Once tissue is engaged with the attachment points, the extension member is pulled until the tissue is approximated in the desired position. Then the appropriate extension member hole(s) are selected to attach the extension member to supportive tissue or bone (for example temporal fascia) for permanent tissue approximation.

  • Publication number: 20040167573
    Abstract: Wire fasteners having legs with lengths that can be one hundred times the width of the fastener are used to secure items, such as prosthesis valves to a patient during minimally invasive surgery. The fasteners are manipulated into position and then are immobilized by means of the legs thereof for tensioning, cutting and forming in situ. The fasteners are manipulated, tensioned and formed from the leg end of the fasteners. Tools for initially placing the fasteners and for immobilizing, tensioning, cutting and bending the fastener legs are disclosed. Once the fasteners are initially placed, the prosthesis is placed on the long legs of the placed fasteners and is guided into position on the legs. Once the prosthesis is in position, the legs of the fasteners are immobilized, tensioned, cut and bent into staple-like shapes to secure the prosthesis to the patient. A method for carrying out the procedure using the long fastener is also disclosed.

  • Patent number: 6776784
    Abstract: A device for closing a septal defect, such as a patent foramen ovale, includes a clip formed from a superelastic material that is inserted into a septum wall of a heart. The clip is advanced through a patient's vasculature, e.g., within a delivery apparatus, until the clip is disposed within a first chamber adjacent the septal defect. Tines of the clip are directed through a flap of tissue of the septal defect until the tines of the clip are disposed within a second opposing chamber. The clip then transforms into its relaxed state, wherein the tines of the clip engage with a surface of the second chamber, thereby substantially closing the septal opening.

  • Patent number: 6645205
    Abstract: Apparatus and methods are provided for reducing the volume of a lung using a clip including a plurality of tines. The clip is advanced along an interior of a bronchial passage to a predetermined location with the tines in a contracted condition. The tines are expanded outwardly to engage surrounding tissue, and then collapsed towards the contracted condition, thereby drawing the surrounding tissue inwardly to substantially close the bronchial passage from air flow therethrough. Optionally, electrical energy may be applied to the surrounding tissue after collapsing the tines to the contracted condition, thereby fusing the surrounding tissue together. The clip is then released within or removed from the passage.

  • Patent number: 6616686
    Abstract: A surgical staple is provided having a base portion and a respective leg extending from each end of the base portion and terminating at a free end. The base portion is deformable to bring the free ends of the legs together to penetrate a liquid-carrying vessel at the site of a puncture and hold the opposite edges of the puncture together. The base portion and legs lie in substantially a common plane except for a center portion (40C) of the base portion which is deformed in a loop in a direction perpendicular to the common plane. The center portion of the staple allows the staple to straddle a blood locator tube projecting from the end of a stapler, so that the staple can be closed at the center of a puncture wound in which the tube is located. A method for stapling is also provided.
