Patent Images
1. A system for delivering energy to a patient'"'"'s body, comprising:
- an energy source;
at least two probe assemblies;
an apparatus coupled to at least two of the probe assemblies, said apparatus operable to reduce a temperature of the probe assemblies to which it is coupled; and
a controller operable to control an operation of said apparatus with respect to each of said probe assemblies to which it is coupled, wherein the operation of said apparatus for one probe to which said apparatus is coupled is independent of the operation of said apparatus for any other probe to which said apparatus is coupled.

Abstract
A novel medical probe assembly, system, and methods for the use thereof to treat tissue are described. The system optionally comprises an energy source, two 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.

14. A method of treating tissue of a patient'"'"'s body, the method comprising:
-
providing an energy source, first and second probe assemblies each comprising an energy delivery device, an apparatus coupled to said first and second probe assemblies, and a controller operable to control an operation of said apparatus with respect to each of said first and second probe assemblies;
inserting the energy delivery devices into spaced-apart treatment sites for said tissue;
delivering energy from said energy source to said tissue through said energy delivery devices; and
delivering a fluid from said apparatus to at least one of said first and second probe assemblies;
wherein said fluid is operable to reduce a temperature of said first and second probe assemblies and wherein the delivery of fluid from said apparatus to said first probe assembly is controlled by said controller independently of the delivery of fluid from said apparatus to said second probe assembly. - View Dependent Claims (15, 16, 17)

18. A system for delivering energy to a patient'"'"'s body, comprising:
-
an energy source;
at least two probe assemblies;
a cooling means coupled to at least two of the probe assemblies, said cooling means operable to reduce a temperature of the probe assemblies to which it is coupled; and
a means for controlling an operation of said cooling means with respect to each of said probe assemblies to which it is coupled, wherein the operation of said cooling means for one probe to which said cooling means is coupled is independent of the operation of said cooling means for any other probe to which said cooling means is coupled. - View Dependent Claims (19, 20)
