  • Patent number: 9333092
    Abstract: An intervertebral scaffolding system is provided having a central beam having a proximal portion having an end, a grafting portion having a top and a bottom, a distal portion having a end, a central beam axis, a graft distribution channel having an entry port at the end of the proximal portion, a top exit port at the top of the grafting portion, and a bottom exit port at the bottom of the grafting portion. These systems can also include a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

  • Patent number: 9265521
    Abstract: Articulating, safe and efficient cutting heads for removing a target tissue from a subject during a surgical procedure are provided, the cutting heads composing a part of systems that address several problems, including clogging of state-of-the-art systems during removal of such tissue, for example. The target tissue can include any tissue that is accessible through a small surgical opening, for example, a joint tissue such as a meniscus or an intervertebral tissue, such as a nucleus pulposus. The devices can be referred to as orthopedic tissue removal devices having cutting heads associated with vacuum systems, making the systems useful in several procedures, including X-LIF (lateral approach to an intervertebral fusions) procedures, T-LIF (transforaminal approach to intervertebral fusions) procedures, P-LIF (posterior approach to intervertebral fusions), and a percutaneous, transforaminal approach (Kambin triangle access).

  • Patent number: 9186259
    Abstract: Systems and methods for distracting an intervertebral disc space are provided. The systems use a staged, bilaterally expandable trial. The systems and methods of distracting an intervertebral space are provided in a manner that addresses the problem of subsidence. The method includes inserting the trial into the intervertebral space in a collapsed state and, once inserted, the trial is then used for distracting the intervertebral space using an expansion that includes a first stage and a second stage. The first stage includes expanding the trial laterally toward the peripheral zones of the top vertebral plate and the bottom vertebral plate, and the second stage includes expanding the trial vertically to distract the intervertebral space.

  • Publication number: 20100004750
    Abstract: The present invention relates to a device and method to 1) facilitate disk fusing, 2) perform an artificial replacement of the nucleus, 3) perform an artificial replacement of the annulus, or 4, perform an artificial replacement of both the nucleus and annulus. The device is designed to be placed into the inter-vertebral space following diskoctomy. The invention includes a delivery catheter and an expandable continuous mesh loop that has a torus configuration with a lumen within the mesh and a central hole. The mesh loop can be diametrically increased or contracted in diameter by the control element acting on the mesh loop. The mesh loop may be formed of a woven or braided material for a polymer such as PEEK (polyetheretherketone), nylon, polyurethane, polyester, polyethylene, polypropylene or any other biocompatible polymer, or formed from a metallic braid of stainless steel, Elgiloy, Nitinol, or any other biocompatible metal.

  • Patent number: 7601172
    Abstract: The present invention relates to a device and method which may be used to reinforce the native annulus during spinal surgery. The device is a catheter based device which is placed into the inter-vertebral space following discectomy performed by either traditional surgical or endoscopic approaches. The distal end of the catheter is comprised of an expansile loop which may be increased in diameter by advancement of a portion of the catheter via its proximal end, such proximal end remaining external to the body. The expansile loop may be formed such that when the loop is diametrically contracted the loop feeds into its other end, similar to a snake eating its own tail. Stabilization of the outer portion of the loop and pulling out the inner portion will thereby increase the overall diameter of the loop while maintaining it as a closed loop or torus. The expansile loop then uses an attachment means to secure it to substantially healthy tissues of the annulus, nucleus, or endplates.
