SYSTEMS FOR THE TREATMENT OF FRACTURED OR SICK BONE USING EXPANSIBLE BODIES.

摘要

System for treating a vertebral body that has a cortical bone that surrounds an inner volume occupied, at least in part, by spongy bone (32), comprising: a first outer guide sleeve (72A) to provide a first access route to the inner volume of the vertebral body, a second outer guide sleeve (72B) to provide a second access path to the inner volume of the same vertebral body, the second access path being different from the first access route, a first expandable body ( 56A) sized and configured to be introduced through one of the first or second access sheath to the inner volume to be expanded to form a first void (84A) in the spongy bone, and a second expandable body (56B) sized and configured to enter through the other of the first or second access sheath to the inner volume to expand to form a second void (84B) in the spongy bone, different from the First void
