Methods of treating the sacroiliac region of a patient's body
A method, system and apparatus are disclosed for performing an electrosurgical treatment procedure on a bodily tissue. An electrosurgical apparatus is described, the apparatus comprising one or more probes having insulated and conductive regions for creating lesions in bodily tissue. A method of delivering energy to a patient's body is described, including methods of treating sacro-iliac related pain using electrosurgical probes.
1. A method of treating at least one target site in a sacroiliac region of a patient's body by delivering energy, the sacroiliac region including a sacrum having a posterior surface and a plurality of foramina extending therethrough, and a sacral neural crescent adjacent the foramina, the method comprising:
inserting a plurality of probes into the sacroiliac region of a patient's body;
positioning each of the plurality of probes with respect to a face of one of the foramina such that an angle between each of the plurality of probes and the face of one of the foramina ranges from 45° to 135°, each of the plurality of probes being inserted so that energy is delivered to at least one of 2 o′clock, 4 o′clock and 6 o′clock positions lateral to the face of one of the foramina, or at least one of 10 o′clock, 8 o′clock and 6 o′clock positions lateral to the face of one of the foramina, when one of the foramina is viewed as a clock face with 12 o′clock in the cranial direction;
delivering energy from an energy source through each of the plurality of probes to the at least one target site in a bipolar configuration, and
cooling at least one probe of the plurality of probes, wherein the at least one cooled probe is positioned from 10 mm to 26 mm from an adjacent probe of the plurality of probes.
2. The method of claim 1 , wherein each of the plurality of probes are positioned with respect to the face of one of the foramina such that an angle between each of the plurality of probes and the face of one of the foramina ranges from 60° to 120°.
3. The method of claim 2 , wherein the angle ranges between 80° to 100° from the face of one of the foramina.
4. The method of claim 1 , further comprising inserting at least one of the one or more probes such that at least a portion of the at least one target site is distal to the distal end of the at least one probe.
5. The method of claim 1 , wherein the at least one target site is located at least 1 cm lateral to the face of one of the foramina.
6. The method of claim 1 , further comprising positioning at least one of each of the plurality probes such that it is perpendicular to the sacrum.
7. The method of claim 1 , further comprising:
repositioning at least one of each of the plurality probes to a repositioned site; and
delivering the energy from the energy source through the at least one of each of the plurality probes at the repositioned site.
8. The method of claim 1 , further comprising forming a lesion in at least a portion of the at least one target site via the delivered energy.
9. The method of claim 8 , further comprising adjusting a parameter of a treatment procedure, wherein a size of the lesion is increased.
10. The method of claim 9 , wherein adjusting the parameter of the treatment procedure comprises repositioning at least one of each of the plurality probes to alter a distance between each of the plurality probes and the at least one target site.
11. The method of claim 9 , wherein adjusting the parameter of the treatment procedure comprises adjusting a length of an electrically exposed conductive region of at least one of each of the plurality probes.
12. The method of claim 9 , wherein adjusting the parameter of the treatment procedure comprises modifying an amount of cooling supplied to at least one of each of the plurality probes.
13. The method of claim 1 , wherein each probe of the plurality of probes is positioned at least 10 mm from each of the other probes of the plurality of probes.
14. The method of claim 1 , wherein the at least one cooled probe is positioned from 15 mm to 26 mm from an adjacent probe of the plurality of probes.
