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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The system of claim 1, wherein the cut-out is in fluid communication with the slot. ### Claim 3 (depends on 1) The system of claim 1, wherein the cut-out is a substantially u-shaped slot. ### Claim 4 (depends on 3) The system of claim 3, wherein the cut-out extends along an upper portion, a side portion substantially perpendicular to the upper portion, and a lower portion substantially parallel to the upper portion. ### Claim 5 (depends on 1) The system of claim 1, wherein the carrier comprises a pair of initial locking surfaces and a pair of final locking surfaces. ### Claim 6 (depends on 5) The system of claim 5, wherein in a retracted position, the protruding locking surface of the first and second tongues engage the pair of initial locking surfaces, and when moved to the deployed position, the protruding locking surfaces of the first and second tongues engage the pair of final locking surfaces. ### Claim 7 (depends on 1) The system of claim 1, wherein the carrier comprises an upper post and a lower post. ### Claim 8 (depends on 7) The system of claim 7, wherein the first anchor comprises a carrier hole for attachment to the upper post of the carrier and the second anchor comprises a carrier hole for attachment to the lower post of the carrier. ### Claim 9 (depends on 1) The system of claim 1, wherein the spacer further comprises a pair of upper recesses and a pair of lower recesses configured to guide the first and second anchors. ### Claim 10 (depends on 9) The system of claim 9, wherein the pair of upper recesses are curved and the pair of lower recesses are curved. ### Claim 11 (depends on 1) The system of claim 1, wherein the cut-out includes a substantially u-shaped slot. ### Claim 12 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. ### Claim 13 (depends on 12) The system of claim 12, wherein the cut-out is in fluid communication with the slot. ### Claim 14 (depends on 12) The system of claim 12, wherein the cut-out is a substantially u-shaped slot. ### Claim 15 (depends on 12) The system of claim 12, wherein the first and second tongues each comprise a protruding locking surface at the free end. ### Claim 16 (depends on 15) The system of claim 15, wherein the carrier comprises a pair of initial locking surfaces and a pair of final locking surfaces. ### Claim 17 (depends on 16) The system of claim 16, wherein in a retracted position, the protruding locking surface of the first and second tongues engage the pair of initial locking surfaces, and when moved to a deployed position, the protruding locking surfaces of the first and second tongues engage the pair of final locking surfaces. ### Claim 18 (depends on 12) The system of claim 12, wherein the carrier comprises an upper post and a lower post. ### Claim 19 (depends on 18) The system of claim 18, wherein the first anchor comprises a carrier hole for attachment to the upper post of the carrier and the second anchor comprises a carrier hole for attachment to the lower post of the carrier. ### Claim 20 An implantable system comprising: a spacer including 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, the spacer further including 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 carrier includes an upper post and a lower post, wherein the first anchor includes a carrier hole for attachment to the upper post of the carrier and the second anchor includes a carrier hole for attachment to the lower post of the carrier.
