METHODS OF THERAPEUTICALLY HEATING A VERTEBRAL BODY TO TREAT BACK PAIN
First Claim
Patent Images
1. A method of therapeutically heating a vertebral body to treat back pain, comprising:
- identifying a vertebral body for treatment, said vertebral body comprising an outer cortical bone region and an inner cancellous bone region, and a basivertebral nerve extending from the outer cortical bone region to within the inner cancellous bone region;
identifying a treatment zone within the inner cancellous bone region of said vertebral body;
inserting a cannula having a curved bore 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 probe having two electrodes within the cannula,wherein the cannula is shaped so as to guide said energy delivery probe towards the midline of the vertebral body;
advancing a distal end of said energy delivery probe 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 probe within or proximate the treatment zone; and
activating the two electrodes to deliver radiofrequency energy within the inner cancellous bone region of the vertebral body sufficient to denervate 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.

12. A method of therapeutically heating a vertebral body to treat back pain, comprising:
-
identifying a residence zone of a basivertebral nerve within the inner cancellous bone region of the vertebral body, the residence zone being located within a posterior section of the vertebral body; inserting two electrodes into a vertebral body, the vertebral body having an outer cortical bone region, an inner cancellous bone region, and a basivertebral nerve; positioning the two electrodes within the residence zone of the basivertebral nerve; and generating a heating zone between the two electrodes to heat the basivertebral nerve. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
