Electrosurgical device for treatment of tissue
First Claim
1. A medical probe assembly for delivering energy to a patient'"'"'s body, the probe assembly comprising:
- an elongate member having a distal region and a proximal region and defining a lumen therebetween;
an energy delivery device associated with said distal region of said elongate member, said energy delivery device comprising a protrusion; and
a temperature sensor associated with said protrusion.

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.
