An electrosurgical probe includes one or more electrode terminal(s) and a return electrode coupled to a high frequency voltage supply. Electrically conductive fluid, such as isotonic saline, is delivered to the electrode terminal, and a high frequency voltage difference is applied between the electrode terminal and the return electrode to treat tissue within the spine. The isotonic saline provides a current flow path between the electrode terminal and the return electrode, and it allows for a new mechanism for ablation or molecular dissociation of tissue within the spine.
What is claimed is: 1. A method for treating tissue within a patient's spine comprising:positioning an electrode terminal within close proximity of a target tissue within the patient's spine; positioning a return electrode within close proximity of the target tissue such that the return electrode does not contact the target tissue; delivering electrically conductive fluid to surround an exposed portion of the electrode terminal with the electrically conductive fluid; and applying a high frequency voltage difference between the electrode terminal and return electrode to treat the target tissue. 2. The method of claim 1 further comprising positioning the return electrode within the electrically conductive fluid to complete a current flow path therebetween.
