  • Publication number: 20120143258
    Abstract: A cannulated bone anchor comprising a self-centering ball-joint suitable for use in a spine stabilization prosthesis which supports the spine while providing for the preservation of spinal motion. The cannulated bone anchor has a deflectable post partially received in a socket of a housing formed in the head of the bone anchor. A centering rod received partially in the post and partially within the housing operates to align the post with the longitudinal axis of the bone anchor. Deflection of the post bends the centering rod which in turn applies a restoring force upon the post. The centering rod includes an inner-superelastic core and an outer polymer sheath.

  • Publication number: 20120123478
    Abstract: A spine stabilization prosthesis which supports the spine while providing for the preservation of spinal motion. The spine stabilization prosthesis incorporates a bone anchor having a deflectable post and a compound spinal rod which provide for load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The bone anchor includes a deflectable post connected by a ball-joint to a bone screw. The compound spinal rod includes a coupling mounted to the deflectable post and connected by a pivoting joint to a rod. The combined motions of the ball-joint and the pivoting joint support a range of motion of adjacent vertebrae which closely approximates the natural range of motion of the spine.

  • Patent number: 8172877
    Abstract: Systems and method in accordance with the embodiments of the present invention can include an implant for positioning within a cervical facet joint for distracting the cervical spine, thereby increasing the area of the canals and openings through which the spinal cord and nerves must pass, and decreasing pressure on the spinal cord and/or nerve roots. The implant can be inserted laterally or posteriorly.

  • Patent number: 8172852
    Abstract: Systems and methods for injecting bone filler into a vertebra, wherein a spinous process and/or lamina can be strengthened by injecting the bone filler into the spinous process and/or lamina. An insertion device including a needle can be positioned proximal to the junction between the spinous process and the lamina of the vertebra when inserting the bone filler. Various embodiments of the needle and needle guide devices can be used to facilitate the process.

  • Patent number: 8157840
    Abstract: A method of inserting an interspinous-process implant includes using an insertion tool. The insertion tool includes an inner shaft disposed at least partially within an outer shaft. The inner shaft is longitudinally displaceable relative to the outer shaft and rotatably engagable with the implant. The implant is alignable with a first engagement portion on the tool, advantageously when a second engagement portion associated with the inner shaft is retracted.

  • Publication number: 20120083843
    Abstract: A spinal implant adapted to be inserted into an interspinous space between adjacent spinous processes includes a proximal section, a central section, and a distal section disposed sequentially along a longitudinal axis. The distal section has feature(s) that allow the implant to be inserted laterally into the interspinous space, such as an approximately helical groove and/or a thread-like structure. The distal tip of the implant tapers inwardly, and may be rounded. The proximal section may include an outwardly extending wing or flange. The implant may include a main body that includes the wing or flange and a spacer slidably mated to the main body through the wing or flange.

  • Publication number: 20120083845
    Abstract: Compound spinal rods function as part of the dynamic stabilization prosthesis to provide load sharing with motion preservation as part of a dynamic stabilization prosthesis. Compound spinal rods are used to span from one vertebra to an adjacent vertebra. Compound spinal rods include a first rod connected by a linkage to a second rod. The linkage allows for movement of the first rod relative to the second rod. The movement permitted by the compound spinal rod is designed to enhance the ability of a dynamic stabilization prosthesis to more closely approximate the natural kinematics of the spine without impairing stabilization of the spine.

  • Patent number: 8147548
    Abstract: Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a spacer and a frame having a central body and a helical shaped wing extending from the central body. The frame can be positioned near about adjacent spinous processes, and can be rotated and urged so that the adjacent spinous processes pass within a groove of the wing, thereby allowing the wing to be arranged on an opposite side of the adjacent spinous processes. The spacer can then be arranged over the frame so that the spacer contacts and distracts the spinous processes, thereby limiting relative movement of the adjacent spinous processes during extension.

  • Patent number: 8128663
    Abstract: A spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy. The implant may provide a spinal extension stop while allowing freedom of spinal flexion. The implant includes a central portion and first, second, third, and fourth arms that extend away from the central portion to form two generally oppositely facing saddles. For some versions, one arm is longer than the other arms. For some versions, all the arms are of different length, with one of the arms being longer than the other three, and one of the arms being shorter than the other three.
