Abstract
An expandable interbody fusion implant device has a frame, two ramp assemblies, a threaded drive shaft and at least one base plate, preferably two. The frame has a first lateral side and a second lateral side and a distal end and a proximal end. Each ramp assembly has a translating ramp with a threaded opening, a first pivoting hinged ramp and a second pivoting hinged ramp. Each base plate is hinged to a first lateral side of the frame. Each base plate is hinged to the distal ramp assembly and the proximal ramp assembly at an end of one of said pivoting hinged ramps of each ramp assembly. The drive shaft has a distal drive shaft component having threads for translating the distal ramp assembly and a proximal drive shaft component having threads for translating the proximal ramp assembly.
