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.
Claims11
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 to at least approximate a 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 first guide member extending from the 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, and wherein a second end, at an opposing end to the first end, of the first guide member is positioned at least approximate the posterior end of the body when the first guide member is at the second position;
- 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.
