  • Patent number: 8926620
    Abstract: In some embodiments, an apparatus includes an elongated member, an expandable member coupled to the elongated member, and an outer sheath. The outer sheath, which can be constructed from a different material than the expandable member, is disposed about the expandable member such that an outer surface of the expandable member is in discontinuous contact with an inner surface of the outer sheath. The expandable member and the outer sheath are configured to cooperatively displace a bone structure when moving between a collapsed configuration and an expanded configuration.

  • Patent number: 8894687
    Abstract: A coupling assembly for use in surgical constructs comprises a first body and a second body. One of the first body and the second body includes a male member and an other of the first body and the second body includes a female member. The male member is sized and shaped to be received within the female member and the female member has an internal bore sized and shaped to receive the male member therein. A raised portion is formed on or attached to the male member. An area of decreased diameter is associated with the internal bore of the female member. The first and second bodies are coupleable to one another by an interference fit when the raised portion of the male member is positioned within the area of decreased diameter associated with the internal bore of the female member.

  • Patent number: 8876829
    Abstract: Methods and apparatus for inserting an implant into an intervertebral cavity between adjacent vertebral bodies provide for: adjust an initial height between inner surfaces of respective first and second ramps of an inserter; simultaneously sliding first and second ramps of the inserter, and the implant, proximally, toward distal ends of the first and second ramps, such that the vertebral contact surfaces of the respective first and second ramps separate and distract the vertebral bodies and receive the implant into the intervertebral space with no compressive loading, while holding an initial angle between the ramps substantially constant.

  • Patent number: 8876868
    Abstract: A spinal fixation device combines an open-headed anchor member, such as a bone screw or a hook, with a closure member to thereby clamp a spinal fixation rod to the anchor member. The anchor member has spaced apart arms forming a rod receiving channel. The arms have arm extensions or tabs connected to main portions of the arms by weakened regions to enable the tabs to be broken-off or separated after the rod is clamped. The closure member and inner surfaces of the arms and tabs have helical anti-splay guide and advancement interlocking flanges formed thereon which cooperate to prevent splaying the arms and extensions as the closure member is advanced into the rod receiving channel. The flanges have anti-splay contours which can be formed on load flanks or stab flanks of the flanges. The load flanks can be oriented in such a manner as to aid in the anti-splay characteristics of the flanges or to control the proportioning of axial stresses between the flanges.
