摘要：
An expandable implant movable between a contracted position and an expanded position, is disclosed. In various embodiments, the implant may include a superior endplate and an inferior endplate having proximal ramps and distal ramps disposed on an interior surface thereof, respectively. In various embodiments, a proximal set screw and a distal set screw may be independently coupled to a proximal wedge and a distal wedge. Upon rotation of the proximal set screw, the proximal wedge may act against the proximal ramps of the superior and inferior endplates and cause the implant to expand at the proximal end. Upon rotation of the distal set screw, the distal wedge may act against the distal ramps of the superior and inferior endplates and cause the implant to expand at the distal end. In some embodiments, a first eyelet and a second eyelet for supporting a corresponding bone screw, respectively, may be included.
