Abstract: The present invention provides an expandable fusion device capable of being inserted between adjacent vertebrae to facilitate the fusion process. The expandable fusion device may include first and second endplates, a translation member configured to expand an anterior side and/or posterior side of the device, a plurality of joists configured to connect the first and second endplates to the translation member, and first and second actuation members disposed internally to the device such that openings on a back side of the device can be used to expand or compress the anterior side, the posterior side, or both and such openings may also be used to introduce graft material into the device.

Abstract: An intervertebral implant may include an expandable implant including a superior endplate and an inferior endplate. Each of the endplates may include a first portion having a solid structure and a second portion having a porosity. The first portion comprises a plurality of transverse struts having voids located between the struts and the second portion comprises a lattice structure formed in the voids. A bone funnel assembly may be used to inject graft material into the implant.

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.

Abstract: An expandable interspinous process fixation system capable of restoring spinal stability and facilitating fusion. In one embodiment, the expandable interspinous process fixation system includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. Each endplate supporting fixed and/or adjustable spinous process engaging plates.

Abstract: The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. The fusion device is capable of being deployed down an endoscopic tube.

Abstract: The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes body, a first endplate, and a second endplate, a middle ramp piece, a stem, and two ramp pins. The middle ramped piece is operable to move to generate lordotic expansion of the first and second endplates followed by parallel expansion. The fusion device is operable to be deployed down an endoscopic tube.
