SYSTEM FOR USE IN TREATMENT OF VERTEBRAL FRACTURES
First Claim
1. A medical osteotome device for treating a vertebral body, comprising:
- a handle having a connector for electrically coupling the osteotome device to a power supply;
a shaft extending from the handle to a working end, where a first conductive portion of the shaft is electrically coupleable to a first pole of the power supply; and
an extendable element extendible from the shaft, where the extendable element is coupleable to a second pole of the power supply, such that when activated, current flows between the extendable element and the shaft; and
wherein an axially-extending surface portion of the working end comprises an electrical insulator.

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.
