摘要： A method and apparatus make a size measurement within an intervertebral space by placing an expandable and contractable device into the intervertebral space, expanding the device, measuring a size characteristic of the space, contracting the device and then removing it. Preferably, a holder is held by a physician with an obround-shaped device being inserted into the space and then turned by a steering mechanism prior to the device expansion. The device is small enough to be passed through an incision in the disc annulus prior to turning and after contraction. The measurement may be accomplished by an external x-ray or other imaging device imaging the expanded device in situ or by mechanically operated devices. An expansion and contraction mechanism such as fluid containing bladder or mechanically shifted members expands the device which later contracts in a controlled manner to the contracted size.

摘要： A method and apparatus for making a size measurement within an intervertebral space by placing an expandable and contractible device into the intervertebral space, expanding the device, measuring a size characteristic of the space, contracting the device and then removing it. The measurement may be accomplished by an external x-ray or other imaging device imaging the expanded device in situ or by mechanically operated devices. An apparatus and method is provided for the measuring of the intervertebral space at a controlled distraction force. The apparatus includes an expandable device for providing a measurement within the intervertebral space and facilitating the measurement of the angulations of the lordotic curve of the intervertebral space.

摘要： The present invention relates to tools and methods for cutting the annulus of a spinal disc. The cutting tools of the invention may be cannulated for use in conjunction with a guide wire. A stop surface of the cutting tool is configured to contact the annulus during cutting to prevent further longitudinal movement of the surgical blade(s) into the annulus, thus limiting the size of the incision(s).

摘要： A motion preserving implant having first and second bearing members and a biasing member disposed therebetween operable to provide resistance to the translation of the bodies with respect to one another. An intervertebral implant having first and second bearing members, a translatable member, a resilient connection between the translatable member and one of the bearing members to allow for relative motion therebetween and bearing surfaces of the translatable member and the other bearing member to allow complex, natural motion between the bearing members. A spinal implant having upper and lower bodies and an articulation surface that allows for polyaxial articulation and translation through a concave articulation surface having a first radius of curvature and a second radius of curvature in at least one plane, and a convex articulation surface having the first radius of curvature in the same plane.
