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.
Claims20
An implantable system comprising:
- a spacer comprising a superior surface, an inferior surface, a first side surface, a second side surface, a distal portion and a proximal portion, the spacer having first and second tongues each defined by a cut-out, the first and second tongues each having an integral end and a free end, wherein the spacer comprises a through hole that extends through the superior surface to the inferior surface and a slot adjacent the first and second tongues;
- a first anchor;
- a second anchor;
- and
- a carrier positioned within the slot and between the first and second anchors, wherein the free ends of the first and second tongues are moveable to engage the carrier and lock the first and second anchors in a deployed position,
- wherein the first and second tongues each comprise a protruding locking surface at the free end.

An implantable system comprising:
- a spacer comprising a superior surface, an inferior surface, a first side surface, a second side surface, a distal portion and a proximal portion, the spacer having first and second tongues each defined by a cut-out extending along an upper portion, a side portion substantially perpendicular to the upper portion, and a lower portion substantially parallel to the upper portion, the first and second tongues each having an integral end and a moveable free end, wherein the spacer defines a slot that extends from the superior surface to the inferior surface adjacent the first and second tongues;
- a first anchor;
- a second anchor;
- and
- a carrier positioned within the slot and between the first and second anchors, wherein the free ends of the first and second tongues are moveable outward to accommodate movement of the carrier and having a resting position to engage the carrier and lock the first and second anchors in position,
- wherein the spacer further comprises a pair of upper recesses and a pair of lower recesses configured to guide the first and second anchors, and the pair of upper recesses are curved and the pair of lower recesses are curved.
