Abstract
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. The intervertebral implant may be configured to transition from a collapsed configuration having a first width and a first height to an expanded configuration having a second width and a second height.
Claims18
An intervertebral implant comprising:
- a front plate and a rear plate together defining a central longitudinal axis;
- a central driver disposed on the central longitudinal axis and coupled between the rear plate and the front plate, the central driver adapted to translate the front plate relative to the rear plate;
- a left side portion assembly and a right side portion assembly, wherein the left and right side portion assemblies each include an upper endplate, a lower endplate, an actuator disposed between the upper and lower endplates, and a front ramp;
- and
- a pair of front linkages pivotably connecting the front plate to the front ramps and a pair of rear linkages pivotably connecting the rear plate to the actuators of the left and right side portion assemblies,
- wherein the left and right side portion assemblies have a laterally collapsed configuration having a first width and a laterally expanded configuration having a second width, and wherein the left and right side portion assemblies have a vertically collapsed configuration having a first height and a vertically expanded configuration having a second height.
