Abstract
An intervertebral implant is provided. The intervertebral implant comprises a first component comprising an outer tissue engaging surface and an inner surface. A second component is connected to the first component, and is relatively moveable therefrom. The second component comprises an outer tissue engaging surface and an inner surface. The second component includes an actuator. A third component is disposed for engagement and is movable relative to the first and second components. The third component comprises at least a first ramp and a second ramp axially spaced apart from the first ramp. The actuator is engageable with the third component to effect axial translation of the wedge such that the ramps engage the inner surface of at least one of the first component and the second component to move the components between a first, collapsed configuration and a second, expanded configuration. Methods of use are disclosed.
