Patent Images
1. A method of heating a vertebral body, comprising:
- identifying a vertebral body for treatment, said vertebral body comprising an outer cortical bone region and an inner cancellous bone region, and at least a portion of a basivertebral nerve within the inner cancellous bone region;
identifying a treatment zone within the inner cancellous bone region of said vertebral body corresponding to a likely location of the portion of the basivertebral nerve;
inserting a cannula through the outer cortical bone region of the vertebral body and into the inner cancellous bone region of the vertebral body;
inserting a flexible radiofrequency energy delivery device having two electrodes within the cannula,advancing a distal end of said energy delivery device out of a distal opening of said cannula and into the inner cancellous bone region of the vertebral body;
positioning the two electrodes of said energy delivery device within or proximate the treatment zone,wherein the step of positioning the two electrodes of said energy delivery device within or proximate the treatment zone comprises positioning a first electrode of the two electrodes on a first side of the vertebral body and positioning a second electrode of the two electrodes on a second side of the vertebral body; and
activating the two electrodes to deliver radiofrequency energy to the treatment zone within the inner cancellous bone region of the vertebral body sufficient to modulate the basivertebral nerve.

Abstract
Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device (e.g., an energy delivery device).
