Claim:
1. A system for accessing and treating a target treatment site within bone, the system comprising: an elongate shaft having a proximal end and a distal end, wherein the proximal end comprises a handle, wherein the elongate shaft comprises a central lumen extending from the proximal end to the distal end; a cannula; a first stylet; a second stylet; and a radiofrequency (“RF”) energy delivery device configured to deliver energy to the target treatment site, wherein the cannula comprises an internal passageway and a first alignment member at a proximal portion of the cannula, wherein the first stylet is sized such that at least a distal tip of the first stylet extends beyond an opening at a distal end of the cannula, wherein the cannula and the first stylet are together configured to be introduced through the central lumen of the elongate shaft, wherein the distal tip of the first stylet is configured to form a first path toward the target treatment site within a cancellous region of the bone as at least the distal tip of the first stylet is advanced beyond the distal end of the elongate shaft, wherein the second stylet is configured to be inserted within the internal passageway of the cannula upon removal of the first stylet, wherein a distal tip of the second stylet is configured to be advanced beyond the opening at the distal end of the cannula to form a second path beyond the first path, wherein the RF energy delivery device is configured to be inserted within the internal passageway of the cannula upon removal of the second stylet and advanced until at least a distal end portion of the RF energy delivery device is beyond the opening at the distal end of the cannula and positioned along the second path, and wherein the RF energy delivery device is configured to heat the target treatment site sufficient to denervate a nerve within the bone.
