Claim Text:
1. An expandable intervertebral implant that extends along a longitudinal axis, the expandable intervertebral implant comprising: a superior bone contacting member including at least a first superior bone contacting component, a second superior bone contacting component spaced from the first superior bone contacting component in a lateral direction that is perpendicular to the longitudinal axis, and a first expandable lateral component interconnected between the first and second superior bone contacting components along the lateral direction; an inferior bone contacting member spaced from the superior bone contacting member in a vertical direction that is perpendicular to both the lateral direction and the longitudinal axis, the inferior bone contacting member including at least a first inferior bone contacting component, a second inferior bone contacting component spaced from the first inferior bone contacting component in the lateral direction, and a second expandable lateral component interconnected between the first and second inferior bone contacting components along the lateral direction; and at least one expandable vertical component interconnected between the superior and inferior bone contacting members along the vertical direction, wherein the implant is expandable in situ in both the vertical direction and the lateral direction from a first insertion configuration to a second expanded configuration, whereby 1) the first expandable lateral component expands in the lateral direction as the first superior bone contacting component and the second superior bone contacting component move away from each other in the lateral direction, 2) the second expandable lateral component expands in the lateral direction as the first inferior bone contacting component and the second inferior bone contacting component move away from each other in the lateral direction, and 3) the at least one expandable vertical component expands in the vertical direction as the superior bone contacting member and the inferior bone contacting member move away from each other in the vertical direction, and wherein the implant is expandable from the first insertion configuration to the second expanded configuration without causing the implant to change in length along the longitudinal axis.
