    摘要: A prosthesis for the replacement of at least a portion of the bone of a facet located on a mammalian vertebra, comprising: an articulating surface that articulates with another facet; a bone contacting surface that contacts a surface of the vertebra, the articulating surface being connected to the bone contacting surface; and a fixation element that attaches the bone contacting surface to the vertebra, the fixation element being adapted for implantation into an interior bone space of a pedicle of the vertebra; wherein the prosthesis is configured so that no portion of the prosthesis contacts the posterior arch of the vertebra.

    摘要: A prosthesis for the replacement of multiple diseased or traumatized spinal facets comprises a portion that replaces at least a bony portion of the facets to be replaced and where the prosthesis attaches to the vertebra in a manner that does not require attachment to, or abutment against, the lamina. Multiple configurations of the prosthesis provide for replacement of the two inferior facets, the two superior facets, a superior and inferior facet, or all four facets. A method of installing the prosthesis is provided that is comprised of the steps of resecting at least a portion of the facets that carry the diseased or traumatized spinal facets and attaching the prosthesis in a manner that does not require attachment or abutment against the lamina.

    摘要: An integrated infusion and aspiration system includes of a flow control system and a catheter assembly. The catheter assembly includes an infusion catheter and an aspiration catheter, each having ports located at the distal end of thereof. The distal ends of the catheters are separated so that the aspiration catheter ports can be positioned on an opposing side of a surgical wound site from the infusion catheter ports. Methods of operation of the integrated infusion and aspiration system provides for uninterrupted aspiration with concurrent controlled delivery of an infusion solution such that the infusion solution is substantially evenly dispersed of over the wound site.
