Abstract
A cavity creation device is introduced into a cancellous bone volume of a vertebral body through a percutaneous access path. The cavity creating device is manipulated to form a cavity in the cancellous bone volume. A volume of filling material is placed in the cavity by introducing a tube through the percutaneous access path and by conveying the filling material through a side dispensing port of the tube.
Claims7
A system comprising
- a guide tool for establishing a percutaneous access path along an access axis to a vertebral body having a cortical wall enclosing a cancellous bone volume, the tool having a distal end, a proximal end, and an inner bore;
- an assembly for conveying a flowable material into the vertebral body, the assembly comprising a filling material dispenser and a tube body sized for passage within the inner bore of the guide tube and including a flexible dispensing end sized and configured for placement within the vertebral body to dispense a volume of filling material in the vertebral body, the assembly further comprising a steering apparatus for deflecting the flexible dispensing end of the tube body within the vertebral body.
