  • Patent number: 11707360
    Abstract: An intervertebral prosthesis for insertion between adjacent vertebrae includes upper and lower prosthesis plates locatable against respective vertebrae and having opposing concavely curved recesses therein, and a core located between the plates. The core has opposed, convexly curved surfaces received in the recesses of the plates to allow the plates to slide in articulated manner over the core. The opposed surfaces of the core and the recesses of the plates have cooperating spherical curvatures. The recess of each plate surrounds a locating peg projecting centrally from the base of the recess and is bounded by an annular rim, such that the annular rims of the plates are arranged to contact one another at a predetermined limit of sliding movement of the plates over the core. The peg locates loosely in an opening located centrally in a curved surface of the core, whereby the plates can slide over the core in all directions while the peg holds the core captive.

  • Patent number: 11607321
    Abstract: An interbody fusion device having an accordion-like structure, wherein the device in inserted into the disc space in its collapsed configuration and then expanded into its expanded configuration by compressing the accordion-like portion of the device. In some embodiments, a pre-formed tube with an accordion-like structure over a portion of its length is inserted in a relaxed (collapsed) configuration, giving the tube a minimum possible diameter. This tube has a cable running through it that is fixed to a distal end portion of the tube and extends past the proximal end portion of the tube to the outside of the patient. Once the tube is positioned on the rim of the endplate, the proximal end of the cable is pulled, thereby tensioning the cable and causing the accordion portion of the tube to become shorter in length but larger in diameter.
