Abstract
Methods and devices that displace bone or other hard tissue to create a cavity in the tissue. Where such methods and devices rely on a driving mechanism for providing moving of the device to form a profile that improves displacement of the tissue. These methods and devices also allow for creating a path or cavity in bone for insertion of bone cement or other filler to treat a fracture or other condition in the bone. The features relating to the methods and devices described herein can be applied in any region of bone or hard tissue where the tissue or bone is displaced to define a bore or cavity instead of being extracted from the body such as during a drilling or ablation procedure.
Claims21
A method of treating a vertebral body, comprising:
- advancing a shaft into a vertebral body, the shaft comprising a bendable segment, a first electrode, and a second electrode;
- heating a portion of the vertebral body adjacent the bendable segment by activating current flow between the first electrode and the second electrode;
- and
- displacing a portion of the vertebral body adjacent a distal end of the shaft by applying an impact force to a handle coupled to a proximal end of the shaft.
A method of treating a vertebral body, comprising:
- advancing a shaft into a vertebral body, the shaft comprising an insulator, a first electrode, and a second electrode, wherein the insulator is radially disposed between the first electrode and the second electrode;
- and
- heating a portion of the vertebral body by introducing RF current along a path extending from the first electrode around the insulator to the second electrode.
A method of treating a vertebral body, comprising:
- advancing a shaft into a vertebral body, the shaft comprising a first electrode, a second electrode, and a handle;
- displacing a portion of the first electrode to increase the effective surface area of the first electrode, wherein the portion of the first electrode is displaced by rotation of a portion of the handle;
- and
- heating a portion of the vertebral body by activating current flow between the first electrode and the second electrode.
