  • Patent number: 8936627
    Abstract: Expandable support devices for tissue repair are disclosed. The devices can be used to repair hard or soft tissue, such as bone or vertebral discs. A method of repairing tissue is also disclosed. Surgical devices and methods for adjusting (e.g., removing, repositioning, resizing) deployed orthopedic expandable support devices are also disclosed. The expandable support devices can be engaged and surgically implanted by an engagement device and affixed to bone to provide stability and support for the devices.

  • Publication number: 20080071356
    Abstract: An expandable support device and methods of using the same are disclosed herein. The expandable support device can expand radially when compressed longitudinally. The expandable support device can be deployed in a bone, such as a vertebra, for example to repair a compression fraction. The expandable support device can be deployed into or in place of all or part of an intervertebral disc. The expandable support device can be deployed in a vessel, in an aneurysm, across a valve, or combinations thereof. The expandable support device can be deployed permanently and/or used as a removable tool to expand or clear a lumen and/or repair valve leaflets.

  • Publication number: 20060241671
    Abstract: An access port for performing surgical procedures within an insufflated body cavity is disclosed. The port is formed from a duct that is inserted into the body cavity, the duct having a stiff sidewall to prevent collapse. The duct contains a flexible tube that has a constricted shape that forms a seal around a surgical instrument inserted through the duct. The tube has an inner membrane with a low coefficient of friction to facilitate passage of surgical instruments through the duct. The tube has an elastic outer membrane to bias it into the constricted shape. The tube may also be pressurized into the constricted shape by gas, gel or liquid. The tube itself may also form a seal in the absence of the tool, or a second seal, such as a duckbill valve, may be positioned within the duct.

  • Publication number: 20060178694
    Abstract: A device positionable in an opening in a flexible membrane or in the lumen of a vessel having a flexible sidewall. The device distends or biases opposite portions defining the opening or forming the vessel sidewall outwardly in the plane of the device. The outward biasing draws opposing portions of the opening or sidewall inwardly in a direction perpendicular to the plane of the device and into apposition or contact.

  • Publication number: 20060052800
    Abstract: A tool for implantation of a flexible substrate into soft tissue is disclosed. The tool has a shaft with a bore. A penetrator tip is positioned at a distal end of the shaft. A handle is positioned at the proximal end. A push rod extends through the bore and is attached at one end to the penetrator tip, and at the other end to a trigger mounted on the handle. The penetrator tip is biased toward the shaft by a spring and captures the substrate between itself and the shaft. The shaft is inserted into soft tissue, drawing the substrate with it. Pulling the trigger releases the substrate from the tool. The shaft is withdrawn, leaving the substrate within the tissue.

  • Publication number: 20050283166
    Abstract: A snare for capturing and removing emboli from vascular vessels is disclosed. The snare is formed from a flexible, resilient sheet attached to an elongated flexible tube and rod assembly. The rod fits within a bore of the tube and the tube and rod are movable relatively to one another. The sheet forms a generally conical basket, one part of which is attached to the tube, the other part being attached to the rod. Relative motion between the tube and the rod causes the basket to deform between a contracted state, wherein it may pass through the vascular vessel, to an expanded state, wherein it may receive and capture an embolus for removal from the vessel.

  • Publication number: 20050283040
    Abstract: A sling for controlling urinary incontinence is disclosed. The sling is formed from a tube having substantially lengthwise inextensible end portions and an elastically lengthwise extensible intermediate portion between the end portions. The intermediate portion has a U-shape which cradles the urethra. The end portions extend through the abdominal tissue to anchor the intermediate portion in position. The sling places the urethra under a transverse compressive load to hold it closed and prevent inadvertent urination. The tube is formed from interlaced filamentary members. Interlacing may be by warp knitting, weaving using a leno weave or braiding using a tri-axial braid structure. The end portions have a rough texture to facilitate anchoring in the tissue of the abdominal wall. The intermediate portion is smooth and soft to prevent tissue erosion.
