First Claim
1. A method of treating an intraosseous nerve within a cancellous bone region of a vertebral body, comprising:
- positioning an electrosurgical device through a cortical shell of a vertebral body and into a cancellous bone region of the vertebral body,wherein said electrosurgical device comprises a hollow electrically conductive shaft mechanically connected to an insulating spacer,wherein said insulating spacer is mechanically connected to an electrically conductive tip,wherein a proximal end of said insulating spacer extends inside a distal end of said hollow electrically conductive shaft,wherein said proximal end of said electrically-conductive tip extends inside said proximal end of said insulating spacer,wherein said hollow electrically conductive shaft is in electrical connection with a power supply via a first lead,wherein said electrically conductive tip is in electrical connection with said power supply via a second lead,wherein said second lead runs through said hollow electrically conductive shaft and said insulating spacer; and
heating an intraosseous nerve by applying a voltage between said electrically conductive tip and said hollow electrically conductive shaft sufficient to generate a current between said electrically conductive tip and said hollow electrically conductive shaft, thereby heating at least a portion of the cancellous bone region of the vertebral body.

Abstract
A method and apparatus for treating an intraosseous nerve. The method includes positioning a hollow shaft through the cortical shell of a vertebral body and into a cancellous bone region of the vertebral body. The hollow shaft includes an annular wall having a longitudinal bore therein, a proximal portion and a distal portion, and a first window extending transversely through the annular wall. An electrosurgical probe is advanced within the longitudinal bore from the proximal portion toward the distal portion. The electrosurgical probe includes a first treatment element at a distal end of the probe, wherein the first treatment element being in electrical connection with a power supply. The first treatment element is slidably disposed within the longitudinal bore so that the first treatment element is advanced radially outward from the window and shaft to affect treatment of the intraosseous nerve within the cancellous bone region.
