  • Patent number: 9011454
    Abstract: Described herein are suture passers that may be used for repair of the meniscus of the knee. These suture passers typically include an elongate body having a pair of arms. One or more of the arms may be radiused at the distal end region relative to the long axis of the device, to better fit between a target tissue and a body non-target tissue (e.g., the curvature of the femoral condyle). The arms may form a distal-facing opening that is configured to fit the target tissue. One arm may be movable in the axial direction (e.g., the direction of the long axis of the device), while the other arm may be bendable. A tissue penetrator may be housed within one of the arms to extend across the distal opening between the arms. Thus, a suture may be passed from a first side of the tissue to a second side.

  • Publication number: 20140276981
    Abstract: Suture passer devices, including suture passers configured with an axially slideable jaw that includes a tissue-penetrating distal end region. Also described are suture passers including jaws housing tissue penetrating needles to pass suture that are substantially thin. Methods of using such devices to pass a suture through tissue are provided.

  • Publication number: 20140074157
    Abstract: Sutures with pre-tied knots for use in percutaneous surgical procedures. Described herein are pre-tied sutures and methods of using them that may be used with a suture passer for percutaneously suturing tissue, including percutaneously passing and securing a loop of suture around a tear in a meniscus tissue of the knee. A suture with a pre-tied knot may include a length of suture and a knot body on the length of suture, and a leader snare tied to the length of suture by the knot body. The leader snare typically has an opening loop (bight or snare) through which an end of the suture may be passed. The tail of the leader snare may be pulled to remove the leader snare for the knot body and draw the end of the suture through the knot body to close the knot, which can then be tightened to secure the tissue.

  • Publication number: 20130331865
    Abstract: Devices, systems and methods for passing a suture. In general, described herein are suturing devices, such as suture passers, as well as methods of suturing tissue. These suture passing devices may include dual deployment suture passers in which a first distal jaw member is moveable at an angle with respect to the longitudinal axis of the elongate body of the device and the second distal jaw member is retractable proximally to the distal end region of the elongate body and/or the first jaw member. Also described herein are suture passers in which the tissue penetrator passing the suture travels in an approximately sigmoidal pathway, with the distal end of the tissue penetrator extending distally from one jaw of the device.

  • Patent number: 8470043
    Abstract: Discectomy or disc preparation system that includes a guide member that is changeable from a deployment configuration for insertion into an intervertebral disc space to a deployed configuration upon being deployed into the intervertebral disc. The system also includes at least one tissue manipulator, such as cutting, scraping and extraction elements, that can be moved or tracked longitudinally along the guide member into and through the intervertebral disc space.

  • Publication number: 20130144388
    Abstract: A spacing device is provided for adjusting the spacing between adjacent vertebral bodies. The spacing device has a distal end with at least one distraction member adapted for insertion into an intervertebral disc space and movable between a low profile first configuration and a higher profile second configuration. Also provided is an actuator for moving the distraction member between the first configuration (for delivery of the distal end of the spacing device to a target disc space) and the second configuration (for manipulation of the space between adjacent vertebral bodies).
