Claim 0:
1. An expandable intervertebral implant comprising:
an upper body portion;
a lower body portion opposite the upper body portion;
a wedge member connecting the upper body portion to the lower body portion;
a graft window provided in at least one of the upper body portion and the lower body portion and incorporated in the wedge member;
a nose member having a distal end and a proximal end opposite the distal end, the nose member slidably connected to the upper body portion and the lower body portion;
an actuator for driving the wedge member, wherein the actuator is interior to the wedge member and a proximal-side end of the actuator is disposed a) inside of the graft window and b) closer to the nose member than a proximal side of the implant opposite the nose member;
a through-hole in the wedge member at the proximal side of the implant for access to a head of the actuator and the graft window,
wherein
translation of the wedge member along the longitudinal axis of the implant displaces the upper body portion and the lower body portion away from each other, thereby expanding the intervertebral implant.
