INTRAOSSEOUS NERVE DENERVATION METHODS
First Claim
1. A method of denervating an intraosseous nerve, comprising:
- identifying a treatment zone within a vertebral body,within a cancellous bone region of a vertebral body;
inserting a radiofrequency (RF) device probe through an outer cortical bone region and into an inner cancellous bone region of the vertebral body to the treatment zone,delivering an RF energy to the treatment zone within the inner cancellous bone region of the vertebral body corresponding to a location between, but exclusive of, the nerve junction and the outer cortical bone region, to denervate an intraosseous nerve,wherein the target treatment zone is proximal to the junction and located between 60% and 90% of the distance between the anterior and posterior outer cortical walls of the vertebral body, thereby facilitating denervation of the intraosseous nerve and its branches downstream of the nerve junction by denervating a single portion of the intraosseous nerve.

Abstract
System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a radial opening at or near the distal end of the trocar. The system includes a curveable cannula sized to be received in the central channel, the curveable cannula comprising a curveable distal end configured to be extended laterally outward from the radial opening in a curved path extending away from the trocar. The curveable cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path.
