  • Patent number: 8128702
    Abstract: An embodiment of a system in accordance with the present invention can include an implant having a spacer with a thickness and a wing, wherein a first configuration of the wing has a first height substantially similar to the thickness and wherein the wing is adapted to be selectably arranged in a second configuration such that the wing has a second height greater than the first height. A periphery of the implant has a shape generally conformal with a shape of an inner surface of a cannula and a cross-sectional diameter smaller than an inner diameter of the cannula. The cannula is inserted such that a proximal end of the cannula is arranged between the adjacent spinous processes. The implant is then urged into position between the adjacent spinous processes by way of the cannula, and subsequently arranged in a second configuration to fix the implant in position.

  • Patent number: 8128661
    Abstract: An implant that is implanted between adjacent spinous processes for the relief of pain associated with the spine. The device has a spacer to distract apart the adjacent spinous processes. To minimize trauma to the patient, the device has a tapered tissue expander to distract a previously created opening between the adjacent spinous processes. The device also has two wings. The position of one wing is adjustable to allow for ease of assembly in a patient.

  • Patent number: 8123752
    Abstract: A method for strengthening a spinous process comprises positioning a framework over an outer surface of the spinous process, the framework comprising a mesh connected to a frame. Bone filler is distributed over the mesh so that the bone filler contacts the mesh and contacts the spinous process. The bone filler is allowed to cure. A jig is positioned at the spinous process so that a slot through the jig is exposed to a side of the spinous process. A cannula is oriented so that the cannula is receivable in the slot, and insertable into the spinous process through the slot. Bone filler is injected into the spinous process by way of the cannula, with the injection terminating when a desired amount of bone filler has been injected into the spinous process. The cannula is then removed and the bone filler allowed to cure within the vertebra. The above steps can also be accomplished simultaneously or in any order.

  • Patent number: 8114134
    Abstract: A dynamic spinal stabilization linkage for use in stabilizing of the spine. The linkage connects adjacent vertebrae to provide load-sharing and stabilization while allowing natural kinematics. The linkage comprises three rigid bodies joined in series with 3-degree-of-freedom spherical joint between each body. The joints have range-of-motion constraints which limit undesirable intervertebral motion.

  • Patent number: 8097024
    Abstract: A dynamic bone anchor for anchoring a spine stabilization assembly which supports the spine while providing for the preservation of spinal motion. The dynamic bone anchor provides load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The dynamic bone anchor includes a deflectable post connected by a ball-joint to a threaded anchor. Deflection of the deflectable post is controlled by a compliant member. The dynamic bone anchor may be used as a component of a dynamic stabilization system which supports the spine while providing for the preservation of spinal motion. The dynamic bone anchor has splines on the outside of the housing to facilitate installation and the secure attachment of spine stabilization components.

  • Patent number: 8092535
    Abstract: Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a first wing, a spacer extending from the first wing, and a distraction guide. The distraction guide is arranged in a first configuration to pierce and/or distract tissue associated with adjacent spinous processes extending from vertebrae of a targeted motion segment. The implant can be positioned between the adjacent spinous processes and once positioned, the implant can be arranged in a second configuration. When arranged in a second configuration, the distraction guide can act as a second wing. The first wing and the second wing can limit or block movement of the implant along a longitudinal axis of the implant.

  • Patent number: 8083772
    Abstract: A versatile dynamic spinal rod and bone anchor assembly for use in a dynamic stabilization system to support the spine while providing for the preservation of spinal motion. Alternative embodiments can be used for spine fusion. The dynamic bone anchor provides load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The dynamic bone anchor includes a deflectable post connected by a ball-joint to a threaded anchor. The dynamic rod connects different levels of the construct in a multilevel construct. The dynamic rod is connected to the dynamic bone anchor by a joint which permits relative movement of the deflectable post and rod reducing the stress exerted upon the bone anchors and spinal anatomy.

The dynamic bone anchor provides load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The dynamic bone anchor includes a deflectable post connected by a ball joint to a threaded anchor. Deflection of the deflectable post is controlled by a compliant sleeve. The force/deflection properties of the dynamic bone anchor may be adapted to the anatomy and functional requirements of the patient. When implanted the pivot point for the deflectable post is placed close to the instantaneous center of rotation of the spine. The dynamic bone anchor may be used as a component of a dynamic stabilization system which supports the spine while providing for the preservation of spinal motion.
