Electrosurgical tissue treatment method
First Claim
1. A method of treating spinal tissue of a patient'"'"'s body, the method comprising:
- providing a system comprising an energy source and first and second internally-cooled probe assemblies, wherein each of the probe assemblies comprises an electrically conductive energy delivery device electrically coupled to said energy source;
inserting the energy delivery devices of said first and second internally-cooled probe assemblies into spaced-apart treatment sites for said spinal tissue; and
delivering energy from said energy source to said spinal tissue through said energy delivery devices.

Abstract
A medical probe assembly, system, and methods for the use thereof to treat tissue are described. The system optionally comprises an energy source, two internally-cooled probe assemblies, and one or more cooling devices to provide cooling to at least one of the probe assemblies. The probe assemblies may be configured in a bipolar mode, whereby current flows preferentially between the probe assemblies. The probe assemblies and system described herein are particularly useful to deliver radio frequency energy to a patient'"'"'s body. RF energy delivery may be used for various applications, including the treatment of pain, tumor ablation and cardiac ablation.

20. A method of treating spinal tissue of a patient'"'"'s body by delivering energy from an energy source to said patient'"'"'s body, the method comprising the steps of:
-
providing first and second internally-cooled probe assemblies and at least one additional electrically conductive component, wherein each of the probe assemblies comprises an electrically conductive energy delivery device electrically coupled to said energy source;
delivering energy from said energy source to spaced-apart treatment sites for said spinal tissue through said energy delivery devices; and
altering an electrical impedance between a current sink and at least one electrically conductive component selected from the group consisting of said first probe assembly, said second probe assembly and said at least one additional electrically conductive component;
whereby altering an electrical impedance serves to adjust a flow of energy between at least two electrically conductive components selected from the group consisting of said first probe assembly, said second probe assembly and said at least one additional electrically conductive component.
