Abstract
Articulating expandable fusion devices, systems, instruments, and methods thereof. The articulating expandable fusion implant having a plurality of links is capable of being deployed and articulated inside an intervertebral disc space link by link. After the links are articulated into a polygonal shape, the links may be expanded outwardly into an expanded configuration. Instruments may be provided to articulate and expand the implant.
Claims20
An expandable implant comprising:
- a cable defining a longitudinal axis;
- an upper body;
- a lower body;
- and
- a core body slidably disposed between the upper and lower bodies, and including a plurality of links each adapted to be arranged in series with each other inside an insertion device with a first one of the links disposed at a distal end and a last one of the links disposed at a proximal end, the cable being routed through each of the links in series such that when one end of the cable is pulled, one end of the first link moves proximally towards one end of the last link, the core body slidable relative to at least one of the upper and lower bodies to expand the upper body relative to the lower body, wherein the core body is slidable in a direction perpendicular to the longitudinal axis of the cable.

An implantable device comprising:
- a cable defining a longitudinal axis;
- an upper body adapted to be in contact with a lower surface of a vertebral body;
- a lower body adapted to be in contact with an upper surface of another vertebral body;
- a core body slidably interposed between the upper and lower bodies, the core body including a plurality of links each adapted to be arranged in series with each other inside an insertion device with a first one of the links disposed at a distal end and a last one of the links disposed at a proximal end, the cable being routed through each of the links in series such that when one end of the cable is pulled, one end of the first link moves proximally towards one end of the last link and expand the upper body relative to the lower body by sliding the core body relative to the upper body to the lower body in a direction perpendicular to the longitudinal axis.
