Interbody fusion device and system for implantation

An implant comprising:

• a body;
• and
• a bone fixation system;
• the body including an interior area disposed between a superior surface and an opposite inferior surface spaced from the superior surface in a vertical direction;
• the bone fixation system including at least one blade disposed within the interior area of the body in an insertion position;
• the bone fixation system further including at least one strike plate engaging the at least one blade in the interior area of the body, the at least one strike plate being configured to move the at least one blade from the insertion position to an impaction position in which at least a portion of the blade protrudes past one of the superior surface and inferior surface of the body;
• and
• the at least one blade including a first blade, wherein movement of the first blade from the insertion position to the impaction position is in a direction at a first non-zero angle with respect to the vertical direction;
• wherein the first blade is disposed on a first side of a lateral centerline of the body and deploys, at the first non-zero angle, toward a vertical plane extending through the lateral centerline of the body.

• and
• the first blade including a first wall and a second wall extending substantially parallel to one another and a third wall longer than the first wall and the second wall and extending between the first wall and the second wall such that the arrangement of the first wall, second wall, and third wall has a U-shaped cross-section in a plane that is substantially perpendicular to the direction in which the first blade is configured to move;
• wherein the third wall of the first blade defines a first plane that is oriented at a first non-zero, oblique, horizontal angle with respect to an anterior-posterior axis of the body.
