Abstract
An elongate inserter has a distal end releasably connected to an expandable interbody fusion device and a proximal end including a trigger actuator. The interbody fusion device comprises a superior endplate and an inferior endplate that are movable in an expansion direction relative to each other in the intradiscal space. The device includes an elevator captively supported between the inferior endplate and the superior endplate for movement independently toward and away from each of the inferior endplate and the superior endplate. The inserter includes a lifting platform that defines lifting surfaces that upon operation of the trigger actuator cooperatively engage complementary lifting surfaces on the elevator and move the inferior endplate away from the superior endplate. A driver is supported by the inserter for pushing an insert into the expanded device between the superior and inferior endplates.
