Thermal denervation devices and methods

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.
