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.

Claim (Index 1):
An expandable interbody fusion implant device comprises:\n a frame having a first lateral side and a second lateral side and a distal end and a proximal end; two ramp assemblies, one being a distal ramp assembly and the other a proximal ramp assembly, each ramp assembly has a translating ramp with a threaded opening, a first pivoting hinged ramp and a second pivoting hinged ramp, each pivoting hinged ramp being pivotably movable about a pinned end by a pivot pin oriented parallel to the second lateral side; a first and a second base plate disposed between the distal end and the proximal end of the frame, each base plate being hinged to a first lateral side of the frame, the first base plate overlying the second base plate, each base plate being hinged to the distal ramp assembly and the proximal ramp assembly at the pivoting end of one of said pivoting hinged ramps of each ramp assembly, each base plate being pivotably affixed to and movable relative to the pivoting hinged ramps, each base plate having pockets for holding each pivoting hinged ramp at the pinned end transverse to the second lateral side; a threaded drive shaft pinned to the proximal end of the frame, the drive shaft having 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, each drive shaft component being coupled to the other, the proximal drive shaft component being affixed to the frame at the proximal end of the frame; and wherein rotation of the drive shaft drives the translating ramp of the distal ramp assembly and the translating ramp of the proximal ramp assembly simultaneously in opposite directions as each of the first pivoting hinged ramp and the second pivoting hinged ramp pivots being moved by the translating ramps wherein each translating ramp has an exterior lift surface to guide and support the pivoting hinged ramps during expansion or contraction of the base plates, and wherein each pivoting hinged ramp has a bearing support surface configured to slide on the exterior lift surface of the translating ramp as the pivoting hinged ramp is moved by the translating ramp to selectively expand or contract a distance between the two base plates laterally relative the second lateral side of the frame, simultaneous rotation of both distal and proximal drive shaft components drives the distal and proximal ramps to selectively expand or contract a distance between both first and second base plates to a selected inclination of the first and second base plates relative to the frame over a range of lordotic angles.
