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.

Intervertebral spacer assemblies, systems, and methods thereof. A method of insertion include inserting an intervertebral spacer and plate together using an insertion tool and, upon removal of the insertion tool, the intervertebral spacer and plate are no longer considered connected/coupled and act as separate components.

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.

Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.

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.

The present invention relates to an expandable implant for engagement between vertebrae generally comprising an inner member, outer member, and gear member positioned coaxial with respect to each other such that the inner and outer members are moveable relative to each other along an axis. The gear member is axially fixed to the outer member and freely rotatable with respect to the outer member and the gear member threadedly engages a threaded portion of the inner member to translate inner member along the axis. The implant is configured to engage the vertebrae in a predetermined alignment and the gear member includes gear teeth exposed to the exterior and configured to be accessible by a tool member at a plurality of angular positions around the perimeter of the implant device.

A spinal implant device has a synthetic or metallic or a combination thereof of these materials in an implant body structure and stem cells in a coating, or a sheet, wrap or a membrane wrap applied to surfaces on the implant body structure or alternatively filled with a plug of stem cell laden material. The implant body structure preferably has an aperture or channel The spinal implant device may include anchoring holes to secure the device to the spinal skeletal structure with fasteners or alternatively can simply be held in place by and between adjacent vertebrae.

A cage for implanting in bone includes a main body having a first surface that contacts a first bone surface, a second surface that contacts a second bone surface, a peripheral wall extending between the first and second surfaces, and a front wall portion configured to engage and fix a plating device on the main body.

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. The intervertebral implant may be configured to transition from a collapsed configuration having a first width and a first height to an expanded configuration having a second width and a second height.

A bone graft delivery system and method for using same to deliver graft material into a surgical site. The system includes an interbody implant having a securing site disposed on a surface of the implant and a holder having an elongated, hollow handle including a distal end. The distal end of the holder is configured to removably engage the securing site of the interbody implant to secure the interbody implant to the distal end of the holder until such time as a user desires to disengage the holder from the interbody implant. The interbody implant may be a cage implant having opposing anterior and posterior surfaces, opposing first and second lateral surfaces, and opposing top and bottom surfaces, wherein the top surface comprises a first aperture and the bottom surface comprises a second aperture, the posterior surface comprising a third aperture, the first, second, and third apertures all linking to a main cavity, the main cavity generally extending between the top surface and the bottom surface.
