INSERTER FOR EXPANDING BODY TISSUE

摘要

An elongate inserter lias a distal, end rele&sably connected to an expandable device for expanding body tissue and a. proximal, end including a trigger actuator. The expandable device- comprises a superior endp!ate and an inferior emipiate that are movable In an expansion direction relative to each other between opposing tissue surikees of a body. The inserter includes a lifting piMform comprising ramp surfaces that upon operation of the trigger actuator -cooperatively engage -complementary surjkses of expansion structure within tbe device to cause the superior and inferior endpktes 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.
