Abstract
A system for treating a vertebral body comprises a cannula leading into a vertebral body and a cavity creating device. The cavity creating device comprises a shaft having a distal end portion sized to extend through the cannula, an expandable body that undergoes expansion between a collapsed condition and an expanded condition to form a cavity in the vertebral body, and a tubular fluid transport member to convey fluid through the distal region of the expandable body and into the cavity. The system further comprises a device coupled to the shaft to change the expandable body between the collapsed condition to the expanded condition. The system further comprises a source of fluid coupled to the tubular fluid transport member to convey fluid through the distal region of the expandable body and into the cavity. The system further includes a device to convey a filling material into the cavity.
