A bone treatment device comprises a shaft (120, 220,450, 502, 552, 602, 604, 702) having a tubular wall (125,225, 454), a lumen (126, 226, 564) extending within the tubular wall, openings through the tubular wall, and anchoring elements (128, 228, 452, 520, 554, 612, 614, 714) adjacent the openings that can be deployed out of the openings in the presence of an actuating force within the shaft lumen. The bone treatment device may further comprise an actuator (130, 230, 300, 400, 730) configured to be received within the shaft lumen to deploy the anchoring elements out of the openings. |
