Abstract
In some embodiments, an intervertebral implant may include a body including a superior and an inferior surface. The implant may include a first channel extending from an anterior end towards the posterior end of the body. The implant may include a first anchor channel The implant may include a first guide member positionable in the first channel The implant may include a first anchor. When the first guide member moves from a first position to a second position the first anchor may be conveyed through the first anchor channel and couple the body to an adjacent vertebra.

An intervertebral implant, comprising:
- a body comprising a superior surface and an inferior surface, wherein at least a portion of the superior surface is configured to contact an endplate of an upper adjacent vertebra during use, and wherein the inferior surface is configured to contact an endplate of a lower adjacent vertebra during use;
- a first channel extending from an anterior end towards the posterior end of the body;
- a first anchor channel, wherein a first end of the first anchor channel is coupled to the first channel adjacent the anterior end and a second end of the first anchor channel extends through the superior or the inferior face of the body;
- a first guide member positionable in the first channel, wherein the first guide member is movable from a first position, a first end of the guide member extending from the anterior end of the body, to a second position, the first end of the guide member substantially flush with the anterior end of the body, during use;
- and
- a first anchor coupled to the first end of the first guide member, wherein when the first guide member moves from the first position to the second position the first anchor is conveyed through the first anchor channel and couples the body to the upper or lower adjacent vertebra during use.

A method of implanting an intervertebral implant within an intervertebral space between endplates of adjacent vertebra, comprising:
- implanting an intervertebral implant between an upper adjacent vertebra and a lower adjacent vertebra such that a superior surface of a body of the intervertebral implant contacts an endplate of the upper adjacent vertebra and an inferior surface of the body contacts an endplate of the lower adjacent vertebra;
- conveying a first guide member through a first channel from a first position, a first end of the first guide member extending from an anterior end of the body, to a second position, the first end of the first guide member substantially flush with the anterior end of the body, during use;
- conveying a first anchor through a first anchor channel when the first guide member moves from the first position to the second position, wherein a first end of the first anchor channel is coupled to the first channel adjacent the anterior end and a second end of the first anchor channel extends through the superior and/or the inferior face of the body;
- and
- coupling the body to at least one of the adjacent vertebrae using the first anchor.

A method of implanting an intervertebral implant within an intervertebral space between endplates of adjacent vertebra, comprising:
- implanting an intervertebral implant between an upper adjacent vertebra and a lower adjacent vertebra such that a superior surface of a body of the intervertebral implant contacts an endplate of the upper adjacent vertebra and an inferior surface of the body contacts an endplate of the lower adjacent vertebra;
- inserting a coupling member of an anchor insertion instrument through an elongated slot and into an expanded opening coupled to the elongated slot in a second end of a first anchor, wherein the first anchor comprises a first end;
- positioning the coupling member within the expanded opening such that the coupling member is inhibited from extraction through the elongated slot of the first anchor;
- retracting an elongated shaft coupled, positionable in an elongated conduit, to the coupling member such that the second end of the first anchor abuts a distal end of the elongated conduit;
- conveying the first anchor through a first anchor channel in a body of the implant using the anchor insertion instrument, wherein a first end of the first anchor channel is coupled to the anterior end and a second end of the first anchor channel extends through the inferior and/or the superior face of the body;
- and
- coupling the body to at least one adjacent vertebra using the first anchor.
An intervertebral implant system, comprising:
- an intervertebral implant comprising:
- a body comprising a superior surface and an inferior surface, wherein at least a portion of the superior surface is configured to contact an endplate of an upper adjacent vertebra during use, and wherein the inferior surface is configured to contact an endplate of a lower adjacent vertebra during use;
- a first anchor channel, wherein a first end of the first anchor channel is coupled to the anterior end and a second end of the first anchor channel extends through the inferior or superior face of the body;
- and
- a first anchor positionable in the first anchor channel, wherein the first anchor comprises a first end and a second end, wherein the second end comprises an elongated slot coupled to an expanded opening comprising a first dimension, and wherein the elongated slot comprises a first height and a first width;
- an anchor insertion instrument comprising:
- an elongated conduit;
- an elongated shaft positioned in the elongated conduit, wherein the elongated shaft is movable within the elongated conduit from a first position to a second position;
- and
- a coupling member coupled to a distal end of the elongated shaft, wherein in the coupling member is positionable in the expanded opening through the elongated slot when the coupling member is oriented in a first position relative to the elongated slot, and wherein when the coupling member is oriented in a second position relative to the elongated slot the coupling member is inhibited from moving through the elongated slot.
