1. A system for channeling a path into bone, comprising:
a trocar having a central channel and an opening at a distal tip;
a curved cannula sized to be received in said central channel and delivered to said opening at the distal tip; and
a curved stylet sized and configured to be introduced within the curved cannula;
the curved cannula comprising a deflectable distal end portion with a preformed curve such that the deflectable distal end portion straightens while being delivered through the trocar and regains its preformed curve upon exiting and extending past the opening at the distal tip of the trocar to generate a curved path in the bone;
wherein the curved cannula comprises a central passageway having a diameter configured to allow a treatment device to be delivered through the central passageway to a location beyond the curved path;
wherein the curved cannula further comprises a locking mechanism disposed at a proximal end, the locking mechanism configured to engage with the trocar to limit advancement of the curved cannula; and
wherein the deflectable distal end portion of the curved cannula comprises a plurality of discrete, interconnected links configured to articulate relative to one another to allow deflection of the distal end portion along the preformed curve;
wherein the curved stylet comprises a shaft disposed within a tube, wherein the tube is movable relative to the shaft and slidable along the shaft from a proximal end of the shaft to a distal end of the shaft; and
wherein a distal end portion of the shaft of the curved stylet has a preformed curve corresponding to the preformed curve of the curved cannula and is configured to straighten when fully retracted into the tube by sliding of the tube to the distal end of the shaft of the curved stylet.
