Abstract

A method is disclosed for the treatment of a thoracic region of a patient'"'"'s body. Embodiments of the method comprise positioning an energy delivery portion of an electrosurgical device to face a segment of a thoracic vertebra at a distance from the segment; and cooling the energy delivery portion and delivering energy through the energy delivery portion.

Claims

1. A method of treating a thoracic region of a patient'"'"'s spine, the method comprising:

inserting a first electrosurgical device at a segment of a transverse process of a first thoracic vertebra;

moving the first electrosurgical device in a substantially cranial direction until a distal tip of the first electrosurgical device slips over a superolateral aspect of the transverse process;

inserting a second electrosurgical device at a segment of a second thoracic vertebra adjacent to the first thoracic vertebra;

moving the second electrosurgical device in a substantially caudal direction until a distal tip of the second electrosurgical device slips over the inferiolateral aspect of the transverse process; and

delivering energy between the first electrosurgical device and the second electrosurgical device in a bipolar manner while substantially cooling the first electrosurgical device and the second electrosurgical device.

2. The method of claim 1, wherein the cooling and the delivering energy cooperate to form a lesion substantially between the first electrosurgical device and the second electrosurgical device.

3. The method of claim 1, wherein the superolateral aspect of the transverse process of the thoracic vertebra comprises a centroid region of a transverse process.

4. A method of treating a nerve in the thoracic region of a patient'"'"'s body, the method comprising:

positioning a first energy delivery portion of a electrosurgical device so as to face a region where the nerve is likely to be found, at a distance from the region, the region being located substantially distal to the first energy delivery portion; and

positioning a second energy delivery portion of the electrosurgical device at a segment of the region adjacent to the nerve;

cooling the first and second energy delivery portions of the electrosurgical device and delivering energy from the first and second energy delivery portions to form a lesion at the nerve.

5. The method of claim 4, wherein the cooling and the delivering energy cooperate to form a lesion at a location at least between the first and second energy delivery portions and a superolateral aspect of the transverse process of the thoracic vertebra.

6. The method of claim 4, wherein the distance between the first and second energy delivery portions and the region is 0.5 mm to 4 mm, respectively.

7. The method of claim 4, wherein the nerve innervates a thoracic facet joint of the patient'"'"'s body.

8. The method of claim 4, wherein the nerve comprises a medial branch of a thoracic dorsal ramus nerve of the patient'"'"'s body.

9. The method of claim 4, wherein the first and second energy delivery portions are positioned at a location in the region bounded by:

a superior margin of the transverse process,

an inferior margin of a superjacent transverse process,

an anterior margin of the transverse process and an anterior margin of the superjacent transverse process,

a posterior margin of a spinous process of the thoracic vertebra,

an inferior articular process of the thoracic vertebra and a superior articular process of a superjacent thoracic vertebra, and

a lateral margin of the transverse process and a lateral margin of the superjacent transverse process.
