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 inserter includes a lifting platform comprising ramps surfaces that upon operation of the trigger actuator cooperatively engage complementary surfaces of expansion structure within the device to cause the superior and inferior endplates to move relatively away from each other. A driver is supported by the inserter for pushing an insert between the superior and inferior endplates after expansion of the device.
