Electrosurgical tissue treatment device
First Claim
1. A device for treating spinal tissue of a patient'"'"'s body, the device comprising:
- an energy source;
first and second probe assemblies;
each of the probe assemblies having an electrically conductive energy delivery device electrically coupled to the energy source;
each of the probe assemblies having an electrothermal device for cooling the probe assembly;
whereby the device is configured so that the energy source delivers energy to the spinal tissue through the energy delivery devices in a bipolar mode that concentrates delivered energy between the energy delivery devices to create a lesion within the spinal tissue while the electrothermal devices cool the probe assemblies.

Abstract
A device for treating spinal tissue of a patient'"'"'s body may include an energy source and first and second probe assemblies. Each of the probe assemblies may have an electrically conductive energy delivery device electrically coupled to the energy source, and may also have an electrothermal device for cooling the probe assembly. The device is configured so that the energy source delivers energy to the spinal tissue through the energy delivery devices in a bipolar mode that concentrates delivered energy between the energy delivery devices to create a lesion within the spinal tissue while the electrothermal devices cool the probe assemblies. Related methods of use include cooling, at times via an electrothermal device.

13. A device for treating spinal tissue of a patient'"'"'s body, the device comprising:
-
an energy source including an electrical generator configured to deliver energy via electrical current in a radio frequency range; first and second probe assemblies; each of the probe assemblies having an electrically conductive energy delivery device electrically coupled to the energy source; and each of the probe assemblies having an electrothermal device for cooling the probe assembly; and each of the probe assemblies includes a temperature sensing element in bidirectional communication with the electrical generator; whereby the device is configured so that the energy source delivers energy to the spinal tissue through the energy delivery devices in a bipolar mode that concentrates delivered energy between the energy delivery devices to create a lesion within the spinal tissue while the electrothermal devices cool the probe assemblies, and wherein the operation of one or more of the energy delivery devices and electrothermal devices is modified based in part on a signal generated by the temperature sensing element. - View Dependent Claims (14, 15)
