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.

First claim

What is claimed is:

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 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 caudal direction until a distal tip of the second electrosurgical device slips over a inferiolateral aspect of the transverse process; and
delivering energy between the first electrosurgical device and the second electrosurgical device in a bipolar manner while 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 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 distal to the first energy delivery portion and containing a transverse process of a first thoracic vertebra; and
moving the first energy delivery portion in a cranial direction until a distal tip of the first energy delivery portion slips over a superolateral aspect of the transverse process;
positioning a second energy delivery portion of the electrosurgical device at a segment of the region adjacent to the nerve;
moving the second energy delivery portion in a caudal direction until a distal tip of the second energy delivery portion slips over a inferiolateral aspect of the transverse process;
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 the 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.
