Claim 5:
6. The spinal implant of claim 4, wherein:
the first wedge includes a first curved upper contact surface and a first curved lower contact surface, the second wedge includes a second curved upper contact surface and a second curved lower contact surface, the third wedge includes a third curved upper contact surface and a third curved lower contact surface, the fourth wedge includes a fourth curved upper contact surface and a fourth curved lower contact surface,
the first and second curved upper contact surfaces contact the first proximal ramps and the first and second curved lower contact surfaces contact the second proximal ramps,
the third and fourth curved upper contact surfaces contact the first distal ramps and the third and fourth curved lower contact surfaces contact the second distal ramps, and
the first, second, third, and fourth curved upper surfaces and the first, second, third, and fourth curved lower surfaces are configured to facilitate adjustment of the angle of inclination between the superior and inferior endplates upon rotating the first set screw along the rotation axis by enabling the respective curved surfaces to pivot on a corresponding ramp of the first and second proximal ramps and first and second distal ramps.
