Claim 16:
17. A method of installing an expandable fusion device, the method comprising:
providing an expandable fusion device comprising:
a first endplate having an outer surface that extends from a first lateral end to a second lateral end, the outer surface being configured to engage a first vertebral body;
a second endplate having an outer surface that extends from a first lateral end to a second lateral end, the outer surface being configured to engage a second vertebral body;
a first ramp having a front side, a back side, and first and second lateral sides, the first ramp configured to engage with both the first and second endplates, the front side facing a direction of insertion of the implant, the back side facing away from the direction of insertion; and
a second ramp having a front side, a back side, and first and second lateral sides, the scone ramp configured to engage with both the first and second endplates, the front side facing the direction of insertion of the implant, the back side facing away from the direction of insertion,
wherein a height of the first lateral side of the second ramp is different than a height of the second lateral side of the second ramp,
wherein the expandable fusion device is movable between a collapsed configuration and an expanded configuration,
wherein in the collapsed configuration the outer surface of the first endplate from the first lateral end to the second lateral end is at a first endplate angle with respect to the outer surface of the second endplate from the first lateral end to the second lateral end,
wherein the first endplate angle is an oblique angle, and
inserting and positioning the expandable fusion device laterally into an intervertebral space in a collapsed configuration
expanding the expandable fusion device into the expanded configuration.
