1. A system for channeling a path into bone, comprising:

  • a trocar having a proximal end, distal end and a central channel;

    wherein the central channel is disposed along a central axis of the trocar and extends from the proximal end toward the distal end;

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

    a curveable cannula sized to be received in said central channel and delivered from the proximal end toward said radial opening;

    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;

    wherein the curveable cannula comprises a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path,wherein the distal end of the curveable cannula is deformable so as to be delivered in a straight configuration through the trocar and deployed in a curved configuration outward from the radial opening at an angle with respect to the central axis; and

    a pull cord coupled to the distal tip of the curveable cannula, the pull cord extending to the proximal end of the trocar;

    wherein the pull cord is configured to apply a tensile force to the distal end of the curveable cannula to bias the curveable cannula into a curved configuration.
