  • Patent number: 10080669
    Abstract: An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

  • Publication number: 20180263789
    Abstract: The present invention provides an expandable fusion device capable of being inserted between adjacent vertebrae to facilitate the fusion process. A method of installing an expandable fusion device may comprise introducing the expandable fusion device into an intervertebral space, wherein the expandable fusion device comprises a proximal end, a distal end, an anterior side connecting the proximal end and the distal end, and a posterior side connecting the proximal end and the distal end, wherein the expandable fusion device has an anterior height on the anterior side and a posterior height on the posterior side. The method may further comprise adjusting the anterior height of the expandable fusion device independently from adjustment of the posterior height. The method may further comprise adjusting the posterior height of the expandable fusion device.

  • Publication number: 20180221167
    Abstract: An expandable implant is disclosed having an adjustable height for insertion between two adjacent bony structures or joint surfaces, for example between two adjacent spinal vertebrae. The implant includes at least one gear associated with at least one threaded shaft. Rotation of the gear engages the threaded shaft to expand the implant. The implant can be inserted in a collapsed configuration and expanded in situ. The invention also provides methods for using the implant to facilitate arthrodesis or fusion of adjacent joint surfaces or spinal vertebrae.

  • Publication number: 20180221155
    Abstract: An intervertebral spacer and stabilization implant includes a plate having sockets configured for retaining a fastener passable through the socket and into an adjacent vertebral body. One or more connecting projections extend from a side of the plate, to mate with projections extending from a spacer body. A plurality of teeth project from at least one of the upper or lower surfaces of the spacer body, and a chamber is formed through the spacer body to enable bone fusion between the vertebrae. The combined plate and spacer may be inserted to lie completely within the intervertebral space, or a portion of the plate may overlie a vertebral body.
