Abstract

A spinal implant particularly adapted for lateral expansion while disposed in the disc space between adjacent vertebrae. The implant includes a first frame member pivotally linked to a second frame member via at least one, and preferably multiple, pivoting links. The implant may be inserted into the disc space in a collapsed configuration using a lateral approach, and then expanded in the anterior-posterior direction (lateral to insertion direction) to a deployed configuration where the first and second frame members are farther apart. The implant may be expanded by holding one frame member and pushing on the other frame member or one or more proximal links linking the two frame members.
