1. A method for channeling a path into bone to a treatment location in the body of a patient, comprising:

  • deploying a trocar through a cortical bone region and into a cancellous bone region of a vertebral body,the trocar having a proximal end, a distal end and a central channel disposed therebetween;

    wherein the trocar comprises a radial opening at or n r the distal end of the trocar, the radial opening being in communication with the central channel;

    delivering a curveable cannula through said central channel and to said radial opening;

    deploying the curveable cannula laterally outward from the radial opening in a curved path extending away from the trocar,wherein the curved path is generated though at least a portion of the cancellous bone region of the vertebral body;

    delivering a treatment device through a central passageway in the curveable cannula to a treatment location beyond the curved path,wherein the treatment location comprises a basivertebral nerve associated with the vertebral body; and

    delivering a therapeutic amount of thermal energy to the treatment location sufficient to denervate at least a portion of the basivertebral nerve using the treatment device.
