    摘要: An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

    摘要: Rod link reducer assemblies, systems, and methods thereof. The rod link reducer assembly provides a manipulator rod having a first end, a second end, and an elongate body extending along a body axis between the first end and the second end. A post extends outwardly from the rod. A rod manipulating joint comprise an elongate joint rod extending along a joint rod axis, a first coupling clamp disposed along the joint rod, the first coupling clamp releasably connectable to the post, and a second coupling clamp disposed along the joint rod adjacent to and rotatable about the joint rod relative to the first coupling clamp. The second coupling clamp is releasably connectable to a shaft. A biasing member is adapted to bias the second clamp against the first clamp.

    摘要: Expandable fusion devices, systems, and methods thereof. The expandable implant may include first and second lateral legs and link plates pivotably joined between them. The lateral legs may include upper and lower endplates configured to engage adjacent vertebrae, an actuator assembly including a rotatable actuator having a shaft and a rotatable nut, and driving ramps positioned along the shaft of the actuator. The actuator assembly may cause independent movement of one or more of the driving ramps, thereby causing an expansion in height of the upper and lower endplates of the lateral legs and passive expansion of the connected link plates.

    摘要: The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.
