A spacer for separating bones of a joint, the spacer includes a first endplate configured to engage a first bone of the joint, and comprising a ramped surface; a tissue engaging subassembly disposed in a compartment of the first endplate; a second endplate configured to engage a second bone of the joint; and a frame subassembly that extends between the first endplate and the second endplate. The frame subassembly comprises a drive nut, a drive shaft coupled to the drive nut, a ramped carriage coupled to the drive shaft, wherein the ramped carriage comprises a ramped surface operable to engage the ramped surface of the first endplate, and an actuation bar coupled to the drive nut comprising a plate operable to engage the tissue engaging subassembly.

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.

An intervertebral implant may include a superior exterior surface, an inferior exterior surface, a first exterior lateral surface, and a second exterior lateral surface. The first and second exterior lateral surfaces may be substantially transverse to the superior and inferior exterior surfaces. The implant may further include a first curved end wall at a first longitudinal extremity of the body. The first curved end wall may include a bore configured to receive a first shaft of a tool. Additionally, the implant may include a second curved end wall at a second longitudinal extremity of the body and an elongated slot extending from a portion of the first curved end wall to a portion of the first exterior lateral surface.

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.

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 an exemplary embodiment, the present invention provides an intervertebral implant. The intervertebral implant may be configured to transition from a collapsed configuration having a first height and a first width to an expanded configuration having a second height and a second width.

An intervertebral implant includes a three-dimensional body and a securing plate. The three-dimensional body includes a front surface and a rear surface. The three-dimensional body further includes a plurality of boreholes for accommodating fixation elements. The intervertebral implant also includes a front plate disposed at the front surface of the three-dimensional body and has a plurality of boreholes. A securing plate can be fastened to the front plate.

Spinal implants that are configured for a minimally invasive approach to a patient's intervertebral disc space, optimized to avoid blood vessels and nervous tissue, maximizing endplate coverage and promoting sagittal balance, are provided. Insertion and fixation can be accomplished through a narrow access window, thereby allowing better access to more spinal levels while being less invasive than other approaches. The spinal implants may facilitate fusion, and include visualization features to assist in the implantation and verify proper placement and vary segmental angle of lordosis. Methods of implanting the spinal implants to treat a patient's spine are also disclosed.

Disclosed is an expandable interbody fusion implant that is configured to have an initial configuration having a first footprint width suitable for being inserted into an intervertebral space and an expanded configuration having a second footprint width that is greater than the first footprint width. The implant may include a first body member and a second body member that is pivotally coupled to the first body member. The implant may be expanded using an inflatable balloon. The implant may be expanded bilaterally such that both body members rotate relative to the other or the implant may be expanded unilaterally such that one of the body members rotates relative to the other.

A bone fusion method, apparatus and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable plates having a central rib. The bone fusion device includes one or more support channels configured to receive an insertion instrument that is then secured to the bone fusion device via a coupling mechanism. As a result, the coupled device is able to be securely positioned between vertebrae using the insertion instrument with minimal risk of slippage.
