Abstract
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.
Claims20
A surgical method comprising:
- providing an intervertebral implant including:
- a body,
- a first endplate disposed on an upper side of the body,
- a second endplate disposed on a lower side of the body,
- a translator coupled to the first endplate, and
- an actuator rotatably coupled to the translator;
- inserting the intervertebral implant into a spinal disc space between two adjacent vertebral bodies;
- and
- rotating the actuator in a first direction causing the first endplate to move from a contracted state to an expanded state,
- wherein the actuator includes a threading received in the translator;
- and
- the translator receives a portion of at least one pin.
A surgical method comprising:
- providing an intervertebral implant including:
- a body,
- a first endplate disposed on an upper side of the body and including a first extension extending downwardly,
- a second endplate disposed on a lower side of the body and including a second extension extending upwardly,
- a translator coupled to the first and second extensions of the endplates,
- an actuator rotatably coupled to the translator;
- and
- inserting the intervertebral implant into a spinal disc space between two adjacent vertebral bodies;
- and
- rotating the actuator in a first direction causing the first endplate to move from a contracted state to an expanded state,
- wherein the actuator includes a threading received in the translator;
- and
- the translator receives a portion of at least one pin.
