Claim 0:
1. An expandable interbody spinal implant comprising:
a proximal end and an opposite distal end;
an upper member having an upper surface extending between the proximal end and the distal end;
a lower member having a lower surface extending between the proximal end and the distal end, the lower member being pivotally connected to the upper member;
a bone graft storage portion provided intermediate the proximal end and the distal end, the bone graft storage portion including a proximal wall and a hollow cavity adjacent the proximal wall, the hollow cavity being configured to be packed with a selected volume of bone growth material, the bone graft storage portion being non-rotatable and capable of being moved forward from a first position to a second position with the first position being closer to the proximal end than the second position, and the bone graft storage portion having at least one slot portion adjacent the proximal wall;
a translational wall movably received in the at least one slot portion formed in the bone graft storage portion, the translational wall being moveable between a lower first position and an upper second position via movement in the at least one slot portion;
a drive link pivotally connected to the upper member, and being slidably mounted relative to the lower member and capable of being moved forward toward the distal end by the bone graft storage portion; and
an actuator opening and an actuator, the actuator opening being positioned proximate the proximal end and being configured for insertion of the actuator therein, the actuator being configured to move the bone graft storage portion between the first position and the second position;
wherein movement of the actuator in the actuator opening moves the bone graft storage portion from the first position to the second position, and correspondingly moves at least a portion of the drive link forward toward the distal end to pivot a portion of the upper member upwardly relative to the lower member; and
wherein pivotal movement of the portion of the upper member moves the translational wall upwardly from the lower first position to the upper second position in the at least one slot portion.
