Abstract:
1. An expandable implant device comprising an intervertebral spacer comprising: a first load-bearing element; a second load-hearing element; a sliding element slidably attached to the first load-hearing element and the second load-bearing element, wherein the sliding element has first and second sliding element ramps and wherein the first load-bearing element has first and second load bearing ramps, and wherein the first and second sliding element ramps are configured to press against the first and second load-bearing ramps, respectively, when the sliding element is translated with respect to the first load-hearing element, and wherein the translation of the sliding element with respect to the first load-bearing element causes the first load-bearing element to move away from the second load-bearing element, and wherein the first load-bearing element and the second load-bearing element and the sliding element have respective centrally located openings therethrough, and the respective openings at least partially align with each other along a direction from the first load-bearing element to the second load-bearing element.
