    摘要： A multi-lumen mold is for the in situ formation of a prosthesis in an intervertebral disc space located between adjacent vertebrae of a patient. The multi-lumen mold a flexible mold, a first lumen, a second lumen and a curable biomaterial. The flexible mold is shaped to be positioned in the intervertebral disc space. The first lumen and the second lumen each have a distal end is fluidly coupled to the flexible mold at a first location and a second location, respectively. The first lumen is shaped to extend out through a first opening extending through one of the adjacent vertebrae when the mold is positioned in the intervertebral disc space. The curable biomaterial is delivered into the flexible mold through at least one of the first and second lumens. The first and second locations can optionally be located on generally opposite sides of the mold, on the same side of the mold, or a variety of other configurations. One or more securing members can be used to secure the mold in the intervertebral disc space. The securing members can engage with the annulus, the end plates, and/or another surface of a vertebrae.

    摘要： A nuclectomy method for creating a nuclear cavity in an annulus located in an intervertebral disc space and for preparing the nuclear cavity to receive an intervertebral prosthesis. An annulotomy is formed in the annulus along an annular axis to provide access to a nucleus. A portion of the nucleus is removed in a first region surrounding the annular axis using at least a first surgical tool. Another portion of the nucleus is removed from a second region using at least a second surgical tool. An evaluation mold is positioned in the nuclear cavity and a fluid is delivered to the evaluation mold so that the mold substantially fills the nuclear cavity. The amount of nucleus removed from the annulus is estimated. One or more of the removing steps are optionally repeated as necessary until an adequate amount of the nucleus is removed from the annulus.
