OG exemplary drawing
 
1. An expandable implant having a distal end and a proximal end, the expandable implant comprising:
a wedge assembly slidably coupled with a ramp assembly and configured to receive a single actuator, the wedge assembly having a proximal wedge and a distal wedge;
an upper endplate assembly slidably coupled with the ramp assembly; and
a lower endplate assembly slidable coupled with the ramp assembly;
wherein:
a first movement of the wedge assembly with the single actuator increases the width of the implant;
a second movement of the wedge assembly beyond the first movement increases the height of the implant; and
the proximal wedge moves toward the distal end of the implant, and the distal wedge moves toward the proximal end, with the first movement.
