Device and method for deployment of an anchoring device for intervertebral spinal fusion

An intervertebral fusion device comprising:

• a spacer, having a superior surface, an inferior surface, and opposing lateral surfaces, the spacer adapted to be implanted between an upper vertebral body and a lower vertebral body, the spacer having a central longitudinal axis that equally bisects a front end and a rear end of the spacer;
• a through-hole configured to receive bone graft material and configured to extend through the superior surface, the inferior surface, and the opposing lateral surfaces;
• and
• an anchoring device having an upper anchor with first and second lateral projections and a lower anchor with first and second lateral projections,
• wherein the upper and lower anchors are adapted to be simultaneously deployed into their respective upper and lower vertebral bodies when force is applied thereto,
• wherein the spacer has an upper guide and a lower guide that are adapted to respectively guide the deployment of the upper and lower anchors into their respective vertebral bodies,
• wherein each of the upper and lower guides are aligned with the central longitudinal axis of the spacer such that the upper and lower guides are each equally bisected by the central longitudinal axis,
• wherein the spacer includes a first plurality of through openings extending entirely through the opposing lateral surfaces and into the upper guide and a second plurality of through openings extending entirely through the opposing lateral surfaces and into the lower guide, wherein the first and second lateral projections of the upper anchor are receivable in the first plurality of through openings and the first and second lateral projections of the lower anchor are receivable in the second plurality of through openings to lock the upper and lower anchors to the spacer.
