摘要

An implantable device may be provided. The implantable device may comprise an upper assembly comprising a ramped base and a pair of opposing windows. The pair of opposing windows may extend upward from either lateral side of the ramped base. A gripping assembly may be disposed in each window. The implantable device may further comprise a lower assembly comprising a ramped base and a pair of opposing windows. The pair of opposing windows may extend down from either lateral side of the ramped base. A gripping assembly is disposed in each window. The implantable device may further comprise a ramped actuator assembly disposed between the upper assembly and the lower assembly. The ramped actuator may be configured to transition the implantable device from a collapsed form having a first height to an expanded form having a second height and wherein the second height is greater than the first height.
