System, device, and method for interbody fusion

A method of installing an implant, the comprising:

• providing the implant, the implant comprising:
• a body defining a superior surface, an inferior surface opposite the superior surface, a first end of the body, a second end of the body opposite the first end, a first lateral side, and a second lateral side opposite the first lateral side;
• and
• a cavity extending into the body and defined by a first interior lateral wall, a second interior lateral wall opposite the first interior lateral wall, a first interior end wall extending from the first interior lateral wall to the second interior lateral wall, and a second interior end wall extending from the first interior lateral wall to the second interior lateral wall, the first interior end wall having a curvature toward the superior surface;
• providing a blade within the cavity in a first position such that the blade is contained within the first interior lateral wall, the second interior lateral wall, the first interior end wall and the second interior end wall;
• inserting the implant into a desired location;
• and
• applying a force to the blade such that the blade translates along a blade guide from the first position to a second position, wherein at least a portion of the blade extends past the superior surface in the second position.

A kit for installing an implant, the kit comprising:

• the implant comprising:
• a body defining a superior surface, an inferior surface, a first end of the body, a second end of the body, a first lateral side, and a second lateral side opposite the first lateral side;
• a cavity extending into the body from the superior surface;
• a bore extending into the second end of the body;
• a blade configured to translate along a blade guide between a first position and a second position, wherein at least a portion of the blade extends past the superior surface in the second position;
• and
• an installation tool comprising:
• a handle;
• a hollow shaft connected to the handle;
• a pusher rod configured to extend through the hollow shaft and into the bore to apply a force to the blade causing the blade to translate from the first position to the second position;
• and
• a graft rod configured to extend through the hollow shaft and introduce graft material into the implant.
