1. An implant, comprising:
a body having a superior surface and an inferior surface, a superior-inferior axis extending through the superior surface and the inferior surface, and a lateral axis extending laterally through the body in a direction substantially perpendicular to the superior-inferior axis;
a first blade having a first retracted position in the body and a first extended position where the first blade extends outwardly from the body;
a blade actuating member configured to translate through the body in directions parallel to the lateral axis;
wherein, when the blade actuating member is moved in a first direction along the lateral axis, the first blade moves towards the first extended position; and
wherein, in the first extended position, the first blade extends from the superior surface at a first non-zero angle with respect to the superior-inferior axis;
the implant further including a second blade having a second retracted position in the body and a second extended position where the second blade extends outwardly from the body;
wherein, when the blade actuating member is moved in the first direction along the lateral axis, the second blade moves towards the second extended position;
wherein, in the second extended position, the second blade extends from the inferior surface at a second non-zero angle with respect to the superior-inferior axis;
wherein the first blade has an outer edge, an inner edge, a first lateral edge and a second lateral edge, and wherein the first blade is only in contact with the body along the first lateral edge and the second lateral edge; and
wherein the body includes a first retaining channel to hold the first lateral edge and wherein the body includes a second retaining channel to hold the second lateral edge, and wherein the first retaining channel and the second retaining channel are each oriented at a non-zero angle with respect to the lateral axis.
