1. An implant comprising a plurality wedge components configured to be inserted into a disc space, the implant comprising:
- a first component having a first ramped surface;
a second component having a complementary ramp surface that is complementary to the first component first ramped surface;
wherein advancement of the second component and complementary ramp surface against the first component and first ramped surface in a first direction causes the first component to move in a second direction that is generally perpendicular to the first direction,wherein said first component and second component have planar surfaces configured to support a force generally perpendicular to said second direction, wherein the planar surfaces of said first component and second component are configured to have an increased surface area to withstand compressive loads generally perpendicular to said second direction.

15. A wedge system configured for insertion of al lens one wedge component into a disc space, comprising:
-
a first wedge component comprising a first wedge component first ramped surface and a planar surface; a wedge system cannula with a longitudinal axis; a ramped insertion tool slideably movable along the longitudinal axis of the wedge system cannula; a first direction parallel to the longitudinal axis of the wedge system cannula; and a second direction generally perpendicular to the first direction, wherein advancement of the ramped insertion tool against the first component in the first direction causes the first component to move in the second direction; and wherein the planar surface of the first component configured tip support a force generally perpendicular to the second direction. - View Dependent Claims (16, 17, 18, 19, 20)
