  • Method and devices for a sub-splenius / supra-levator scapulae surgical access technique
    Patent number: 9622779
    Abstract: A novel posterolateral inter-muscular approach has been developed to access the cervical spine. The approach includes elevating the splenius capitis and trapezios muscles dorsally to create a window for deep spine access, wherein the window comprises i) an anterior superior border of the trapezius muscle; ii) an anterior inferior border of the splenius capitis muscle, and iii) a posterior superior border of the levator scapulae muscle. Preferably, a device such as an implant or an instrument is then passed through the window to manipulate the spine.

  • Expandable ring intervertebral fusion device
    Patent number: 9615933
    Abstract: An expandable tube having a substantially semicircular unexpanded shape is inserted into the disc space after the disc material has been removed therefrom. A plurality of expandable lockable rings are passed over this tube in their unexpanded states and positioned along the anterior edge of the endplates. The tube is then expanded, thereby forcing the rings to expand. The rings hold their final expanded configuration via a one-way locking mechanism. Once sufficient distraction is achieved and the rings locked, the tube is collapsed and removed, thereby leaving the expanded, locked rings behind to support the disc space.

  • METHODS AND DEVICES FOR SPINAL CORRECTION
    Publication number: 20160374660
    Abstract: An expandable trial can include an inferior portion, a superior portion, and a middle expanding portion as well as load cells for monitoring the load on the trial. The trial may also include recesses on its lateral sides to provide spacing to accommodate a disc removal tool so tissue can be cleared monitoring load. In addition, neural foramen spacing can be monitoring to provide information about how much neural release has been achieved as the disc is cleaned and the spine is positioned and repositioned.

  • Anti-Backup Suture Anchor
    Publication number: 20160367237
    Abstract: Devices and methods are provided herein that generally involve suture anchors having one or more anti-backup features configured to resist or prevent backward movement of a suture that is pulled through the suture anchor. In some embodiments, the suture anchor can be configured to permit a suture to slide freely in one direction but resist or prevent suture movement in the opposite direction. For example, cleats can be rotatably mounted within the suture anchor, can project radially outward from an exterior sidewall of the suture anchor, or can project circumferentially from sidewalls of one or more channels formed in the suture anchor's exterior surface.

  • Methods and devices for tissue retraction
    Patent number: 9521997
    Abstract: Methods and devices are provided for retracting tissue. In one exemplary embodiment, a retractor is provided that includes a base, a plurality of blades extending from the base, and an actuator coupled to the base and operatively connected to the blades. The actuator can be configured to be actuated to move the blades relative to the base, thereby allowing the blades to retract tissue. The actuator can be self-locking so as to allow the blades to be freely movable within their entire range of motion relative to the base through actuation of the actuator without using another mechanism to lock the blades in a fixed position and to unlock the blades from the fixed position. The retractor can be formed from one or more radiolucent materials.

  • Nubbed Plate
    Publication number: 20160324660
    Abstract: A separate nub component between the plate and an intervertebral fusion cage, wherein the nub is attached to the plate. The nub lessens the undesired pivotal movement of the plate. It is believed that when the nub fits snugly between the endplates of the adjacent vertebral bodies, it acts as a stop against the undesired pivotal movement of the plate.

  • Highly Lordosed Fusion Cage
    Publication number: 20160302938
    Abstract: A fusion cage has a first component that defines an outside surface that is configured to engage a vertebral endplate, and an interior surface. The fusion cage has a second component that defines first and second opposed surfaces. One of the first and second opposed surfaces can mate with the interior surface of the first component. The fusion cage can include vertical and lateral throughholes adapted to enhance fusion.

  • TETHER TENSIONING INSTRUMENT
    Publication number: 20160296265
    Abstract: Various methods and devices are provided for tensioning a tether. In one embodiment, a tether tensioning device is provided and includes a tensioning mechanism adapted to couple to a tether extending along a path between at least two bone anchors implanted in adjacent vertebrae. The tensioning mechanism can be adapted to apply a tensioning force to the tether along the path of the tether to thereby move the tether along the path. The device further includes an actuation mechanism movably coupled to the tensioning mechanism such that the actuation mechanism is adapted to effect movement of the tensioning mechanism to control the tensioning force applied to the tether.
