Electrosurgical tissue treatment method
First Claim
1. A method of treating spinal tissue of a patient'"'"'s body, the method comprising:
- providing a system including an energy source, a first probe assembly, and a second probe assembly, wherein the first probe assembly and the second probe assembly each comprise an electrically conductive energy delivery device electrically coupled to the energy source;
inserting the electrically conductive energy delivery devices of the first probe assembly and the second probe assembly into spaced-apart treatment sites for the spinal tissue;
delivering energy from the energy source to the spinal tissue through the electrically conductive energy delivery devices of the first probe assembly and the second probe assembly by delivering energy in a bipolar manner, whereby delivered energy is concentrated between the electrically conductive energy delivery devices of the first probe assembly and the second probe assembly so as to form a bipolar lesion;
subsequently delivering energy from the energy source to the spinal tissue through each of the electrically conductive energy delivery devices of the first probe assembly and the second probe assembly in a monopolar manner, whereby delivered energy is concentrated separately around each of the electrically conductive energy delivery devices of the first probe assembly and the second probe assembly so as to form a first monopolar lesion and a second monopolar lesion, each of the first and second monopolar lesions overlapping the bipolar lesion; and
repositioning at least one of the first probe assembly and the second probe assembly between one or more of the delivering energy steps.

Abstract
Methods of treating spinal tissue of a patient'"'"'s body are disclosed, some including providing a system including an energy source and first and second probe assemblies, wherein each of the probe assemblies includes an electrically conductive energy delivery device electrically coupled to the energy source; inserting the energy delivery devices of the first and second probe assemblies into spaced-apart treatment sites for the spinal tissue; and delivering energy from the energy source to the spinal tissue through the energy delivery devices. Various options and modifications are possible. For example, energy may be delivered in both a bipolar manner and a monopolar manner, and at least one of the first ad second probe assemblies may be repositioned before again delivering energy.

4. A method of treating spinal tissue of a patient'"'"'s body, the method comprising:
-
providing a system including an energy source having a first probe assembly and a second probe assembly, wherein the first probe assembly and the second probe assembly each include an electrically conductive energy delivery device electrically coupled to the energy source; inserting a first introducer tube into the spinal tissue of the patient'"'"'s body lateral to a Superior Articular Process at a first insertion angle β
1 from a saggital plane, wherein the first insertion angle β
1 is from 20 degrees to 45 degrees;advancing the first introducer tube until a distal tip of the first introducer tube reaches a medial border of the pedicle; inserting a second introducer tube at an opposing insertion angle β
2 into the patient'"'"'s body on an opposite side of the Superior Articular Process than the first introducer tube such that distal tips of the first introducer tube and the second introducer tube are located at spaced-apart treatment sites of the Superior Articular Process, wherein the opposing insertion angle β
2 is substantially equal to the first insertion angle β
1;inserting the electrically conductive energy delivery devices of each of the first probe assembly and the second probe assembly into the first introducer tube and the second introducer tube, respectively; delivering energy from the energy source to the spinal tissue through the electrically conductive energy delivery devices of each of the first probe assembly and the second probe assembly so as to form a bipolar lesion; subsequently delivering energy through each of the first probe assembly and the second probe assembly so as to form a first monopolar lesion and a second monopolar lesion, wherein the first and second monopolar lesions each overlap the bipolar lesion; and repositioning at least one of the first probe assembly and the second probe assembly between one or more of the delivering energy steps. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
