1. A method of denervating a nerve within a vertebral body, comprising:

  • inserting a curved stylet within a lumen of a curved cannula such that a distal end of the curved stylet extends beyond an open distal end of the curved cannula;

    inserting the curved cannula and the curved stylet together within an inner cancellous bone region of the vertebral body;

    advancing the curved cannula and the curved stylet together toward a midline of the vertebral body, thereby forming a curved path within the inner cancellous bone region of the vertebral body;

    removing the curved stylet from the curved cannula;

    inserting a channeling stylet within the lumen of the curved cannula,wherein the channeling stylet is flexibly deformable to navigate the curved cannula yet retain a straight form upon exiting the open distal end of the curved cannula;

    advancing a distal end of the channeling stylet out of the open distal end of the curved cannula and beyond the curved path to form a linear path;

    removing the channeling stylet;

    inserting an energy delivery device through the curved cannula and positioning a distal end of the energy delivery device within the linear path, anddelivering energy to the inner cancellous bone region of the vertebral body sufficient to denervate at least a portion of a basivertebral nerve within the vertebral body.
