EXPANDABLE FUSION DEVICE AND METHOD OF INSTALLATION THEREOF

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 central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. The fusion device is capable of being deployed down an endoscopic tube.

主权项

1. An expandable implant, having a proximal end and a distal end, comprising:
a first endplate extending from the proximal end to the distal end; a second endplate opposed to the first endplate extending from the proximal end to the distal end; a central ramp positioned between the first endplate and the second endplate; a driving ramp positioned at the proximal end, wherein the driving ramp is operably connected with the central ramp; an actuator assembly configured to move the driving ramp; an upper plate member disposed on the proximal end and configured to removably engage the first endplate; and a lower plate member disposed on the proximal end and configured to removably engage the second endplate, wherein the upper plate member and the lower plate member are each further configured to receive one or more bone fasteners.
