ABSTRACT:
Tissue is retracted from a bone during spinal and other procedures by inserting an elongate balloon into a cannula, and guiding the cannula into position along between the tissue and the bone surface. The cannula is then partially withdrawn, and the balloon is inflated to retract the tissues. The method can be performed percutaneously, with minimal tissue damage.
