Abstract
A device and methods for intervertebral spinal fusion of adjacent intervertebral bodies. An intervertebral spacer is positioned within a narrow disc space between adjacent intervertebral bodies of a patient. The spacer is arranged with upper and lower guides. The guides are adapted to simultaneously guide the deployment of upper and lower anchors of an anchoring device into their respective intervertebral bodies. The spacer is also adapted to lock the upper and lower anchors to the spacer in the deployed position.
Claims10
An intervertebral fusion device comprising:
- a spacer having a superior surface, an inferior surface, opposing lateral surfaces, an upper guide, and a lower guide, wherein the spacer is adapted to be implanted between an upper vertebral body and a lower vertebral body;
- an anchoring device having an upper anchor and a lower anchor, wherein the upper and lower anchors are adapted to be simultaneously deployed into their respective vertebral bodies along the upper and lower guides when an anchor driver applies force to the upper and lower anchors simultaneously;
- and
- a locking cap configured to lock the upper and lower anchors in their deployed position,
- wherein the anchoring device is a single unitary piece;
- and
- wherein the single unitary piece has an underside that presses against the upper and lower guides in order to radially deploy the upper and lower anchors into their respective vertebral bodies.
The intervertebral fusion device of claim 5, wherein the first and second grippers are respectively adapted to pivot inwardly about a first pivot point and a second pivot point as the anchor driver is advanced between the pair of leaf springs.
An intervertebral fusion device comprising:
- a spacer having a superior surface, an inferior surface, opposing lateral surfaces, an upper guide, and a lower guide, wherein the spacer is adapted to be implanted between an upper vertebral body and a lower vertebral body;
- and
- an anchoring device having an upper anchor and a lower anchor, wherein the upper and lower anchors are adapted to be simultaneously deployed into their respective vertebral bodies along the upper and lower guides when an anchor driver applies force to the upper and lower anchors simultaneously;
- wherein the anchoring device has a drive plate from which the upper and lower anchors extend, the drive plate having a through-hole for receiving a pull screw;
- and the pull screw is adapted to be threaded into a threaded hole arranged within the spacer for advancing the drive plate towards the spacer.
