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: Retractor blade assemblies, retractors, kits, and methods of using the same. The retractor blade assembly may include a retractor blade, a pedicle screw, and a shim that connects the pedicle screw to the retractor blade. The retractor blade may have a proximal end configured to engage a retractor body and a distal end configured to retract soft tissue. The pedicle screw may have a head portion removably connected to the distal end of the retractor blade and a shaft portion configured to engage the pedicle of a vertebra. The shim couples the pedicle screw to the retractor blade. For example, the shim may include an extension portion configured to engage the retractor blade and a connection portion configured to receive and temporarily lock the pedicle screw to the retractor blade.

Abstract: Devices, systems, and methods for inserting a vertebral stabilization member, such as a rod. The insertion device includes an outer guide tube, a pin assembly including a pin and a pusher member extending therethrough. The insertion device is configured to actuate a rod between a first orientation and a second orientation angled with respect to the first orientation in order to position the rod in an appropriate location for attachment to bone.

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: 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.
