  • Interspinous process implant having deployable wing and method of implantation
    Patent number: 7749252
    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.

  • LOAD-SHARING BONE ANCHOR HAVING A NATURAL CENTER OF ROTATION AND METHOD FOR DYNAMIC STABILIZATION OF THE SPINE
    Publication number: 20100168795
    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 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.

  • LOW PROFILE SPINAL PROSTHESIS INCORPORATING A BONE ANCHOR HAVING A DEFLECTABLE POST AND A COMPOUND SPINAL ROD
    Publication number: 20100145388
    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.

  • Method of laterally inserting an artificial vertebral disk replacement implant with curved spacer
    Patent number: 7691146
    Abstract: In various embodiment of the invention an implant can be placed between two adjacent vertebral bodies using a lateral insertion method. The implant is characterized as having a first end plate and a second end plate which a crossbar spacer there between. The crossbar spacer preferably fits within a channel on the inner surfaces of the first end plate and the second end plate, where the spacer allows the first end plate to pivot, twist and/or rotate relative to the second end plate. The first end plate and the second end plate include a keel extending therefrom, where the keel traverses longitudinally between a first lateral side and a second opposed lateral side and is substantially perpendicular to the sagittal plane of the patient's spine.

  • Laterally insertable artifical vertebral disk replacement implant with curved spacer
    Patent number: 7670377
    Abstract: An intervertebral disk implant is adapted to be placed between two vertebrae using a lateral insertion method. The implant is characterized by features including a first end plate having a first socket and a second end plate having a second socket with a spacer that is at least partially received in the first socket and the second socket. The implant includes at least one keel that is adapted to be inserted laterally into a vertebral body of the spine. The spacer allows for pivotal or rotational motion and also for twisting motion of the spine once the implant is inserted between vertebrae of a patient.
