an inferior component, including: a first proximate end connected to the support component; a first distal end; a first top surface; and, a first bottom surface; a superior component, including: a second proximate end connected to the support component; a second distal end; a second top surface; and, a second bottom surface; and, a balloon connected to the first top surface and the second bottom surface and operatively arranged to expand the expandable intervertebral implant. ### Claim 2 (depends on 1) The expandable intervertebral implant as recited in claim 1, wherein the superior component is hingedly connected to the support component. ### Claim 3 (depends on 1) The expandable intervertebral implant as recited in claim 1, wherein the inferior component is hingedly connected to the support component. ### Claim 4 (depends on 2) The expandable intervertebral implant as recited in claim 2, wherein the superior component is connected to the support component via one or more hinges. ### Claim 5 (depends on 2) The expandable intervertebral implant as recited in claim 2, wherein the support component comprises: a first cross-member; a second cross-member; and, one or more vertical members connecting the first and second cross-members. ### Claim 6 (depends on 5) The expandable intervertebral implant as recited in claim 5, wherein the first cross-member comprises a first flange having a first through-bore. ### Claim 7 (depends on 6) The expandable intervertebral implant as recited in claim 6, wherein the second cross-member comprises a second flange having a second through-bore. ### Claim 8 (depends on 5) The expandable intervertebral implant as recited in claim 5, wherein each of the one or more vertical members is adjustable in length. ### Claim 9 (depends on 8) The expandable intervertebral implant as recited in claim 8, wherein at least one of the one or more vertical members comprises a plurality of locking pins operatively arranged to lock the one or more vertical members at a length. ### Claim 10 (depends on 2) The expandable intervertebral implant as recited in claim 2, wherein the inferior component further comprises a first aperture and the superior component further comprises a second aperture. ### Claim 11 (depends on 2) The expandable intervertebral implant as recited in claim 2, wherein the balloon comprises at least one port, wherein the at least one port is operatively arranged to allow fluid to be injected into and inflate the balloon. ### Claim 12 (depends on 11) The expandable intervertebral implant as recited in claim 11, further comprising at least one tube connected to the at least one port. ### Claim 13 (depends on 2) The expandable intervertebral implant as recited in claim 2, wherein when the expandable intervertebral implant is in a fully expanded state, the superior component is substantially parallel to the inferior component. ### Claim 14 (depends on 1) The expandable intervertebral implant as recited in claim 1, further comprising at least one limit cord operatively arranged to limit the expansion of the intervertebral implant. ### Claim 15 An expandable intervertebral fusion implant, comprising: a support component; at least one inferior component, including: a first proximate end connected to the support component; a first distal end; a first top surface; a first bottom surface; and, a first aperture; at least one superior component, including: a second proximate end connected to the support component; a second distal end; a second top surface; a second bottom surface; and, a second aperture; and, an expansion mechanism arranged between the first top surface and the second bottom surface and operatively arranged to be expanded to displace the at least one superior component relative to the at least one inferior component. ### Claim 16 (depends on 15) The expandable intervertebral fusion implant as recited in claim 15, wherein the at least one superior component is hingedly connected to the support component. ### Claim 17 (depends on 15) The expandable intervertebral fusion implant as recited in claim 15, wherein the at least one superior component is connected to the support component via one or more hinges. ### Claim 18 (depends on 15) The expandable intervertebral implant as recited in claim 15, wherein the support component is adjustable in length. ### Claim 19 (depends on 15) The expandable intervertebral implant as recited in claim 15, wherein the expansion mechanism is a balloon comprising at least one port, wherein the at least one port is operatively arranged to allow fluid to be injected into and inflate the balloon. ### Claim 20 (depends on 15) The expandable intervertebral implant as recited in claim 15, further comprising at least one limit cord operatively arranged to limit the displacement of the at least one superior component relative to the at least one inferior component.
