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 body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

Abstract: Intradiscal fixation device assemblies, systems, and methods thereof. An intradiscal anchor fixation device includes an anchor block and at least one anchor attached to or extending through the anchor block to anchor the device to a vertebral body.

Abstract: Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. An implant for stabilizing an inferior vertebra and a superior vertebra may include a first member and a second member moveably connected to the first member. The implant may have a first, initial insertion orientation and a second, final implantation orientation different from the first, initial insertion orientation. The first member may be configured to be inserted through a pedicle of the inferior vertebra and the second member may be configured to engage bone of the superior vertebra in the second, final implantation orientation.

Abstract: Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. A pedicle-based intradiscal implant for stabilizing an inferior vertebra and a superior vertebra may include a bendable rod configured to engage bone, a bone fastener defining a channel for receiving the bendable rod, and a locking cap for securing the bone fastener and the bendable rod. The implant may be positioned through a pedicle of an inferior vertebra and the bendable rod may be deployable into the vertebral body of the inferior vertebra, through the disc space, and into the vertebral body of the superior vertebra to stabilize the spine.

Abstract: A spacer separates bones of a joint using a driver tool having a threaded shaft. The spacer has a superior endplate with inferior facing ramps, and an inferior endplate with superior facing ramps. Two bearings are positioned between the endplates, each bearing has superior facing ramps which mate with the inferior facing ramps of the superior endplate, and inferior facing ramps which mate with the superior facing ramps of the inferior endplate. One bearing has a threaded aperture, and the other a thrust surface. A threaded shaft is threaded into the threaded aperture to push against the thrust surface to drive the bearings apart. As the bearings move apart, the mated ramps slide against each other to drive the superior and inferior endplates apart.

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: A two part annulus repair rivet for repairing a defect in the annulus of an intervertebral disc includes a first part delivered through a port and adapted to be positioned at an internal surface of an annulus adjacent a defect and a second part adapted to be positioned on an external surface of the annulus adjacent the defect. The first and second parts are secured together, repairing the defect.

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.
