Abstract
An implant including first and second end plates, each of which defines at least one anterior ramped surface and at least one posterior ramped surface. A posterior actuator is positioned between the first and second end plates and has guiding ramp surfaces which correspond with the posterior ramped surfaces. An anterior actuator is positioned between the first and second end plates and guiding ramp surfaces which correspond with the anterior ramped surfaces. An actuator assembly extends between the posterior actuator and the anterior actuator and is configured to selectively move the posterior actuator and the anterior actuator simultaneously, move posterior actuator independently of the anterior actuator, or move the anterior actuator independently of the posterior actuator.
