Abstract

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.

Claims

1. A method of treating the sacroiliac region of a patient'"'"'s body by delivering energy, the method comprising:

inserting one or more probes into the sacroiliac region of a patient'"'"'s body;

positioning the one or more probes lateral to a posterior sacral foramen between a lateral edge of the posterior sacral foramen and a sacroiliac joint; and

delivering energy from an energy source through the one or more probes to at least one target site within the sacroiliac region of a patient'"'"'s body, wherein the at least one target site is lateral to the posterior sacral foramen between the lateral edge of the posterior sacral foramen and the sacroiliac joint.

2. The method of claim 1, wherein at least one of the one or more probes is cooled.

3. The method of claim 1, wherein the energy is delivered in a monopolar, bipolar, multipolar, or triphasic manner.

4. The method of claim 1, wherein at least one of the one or more probes is positioned such that it is substantially perpendicular to the sacrum.

5. The method of claim 1, further comprising:

repositioning at least one of the one or more probes; and

delivering energy from the energy source through the at least one of the one or more probes at the repositioned site.

6. The method of claim 1, wherein the energy delivered is sufficient to form a lesion in at least a portion of the at least one target site.

7. The method of claim 6, further comprising:

adjusting a parameter of a treatment procedure, whereby a size of the lesion is increased.

8. The method of claim 7, wherein adjusting a parameter of the treatment procedure comprises repositioning at least one of the one or more probes to alter a distance between the one or more probes and the at least one target site.

9. The method of claim 7, wherein adjusting a parameter of the treatment procedure comprises adjusting a length of an electrically exposed conductive region of at least one of the one or more probes.

10. The method of claim 7, wherein adjusting a parameter of the treatment procedure comprises modifying an amount of cooling supplied to at least one of the one or more probes.

14. The method of claim 1, wherein at least one of the one or more probes is positioned at least 1 cm lateral to the posterior sacral foramen between the lateral edge of the posterior sacral foramen and the sacroiliac joint.

11. A method of treating the sacroiliac region of a patient'"'"'s body by delivering energy, the method comprising:

determining initial values of one or more parameters of a treatment procedure;

inserting one or more probes into the sacroiliac region of a patient'"'"'s body, wherein at least one of the one or more probes are positioned lateral to a posterior sacral foramen between a lateral edge of the posterior sacral foramen and a sacroiliac joint;

delivering energy from an energy source through the one or more probes to at least one target site within the sacroiliac region of a patient'"'"'s body, wherein the at least one target site is lateral to the posterior sacral foramen between the lateral edge of the posterior sacral foramen and the sacroiliac joint;

measuring the one or more parameters; and

modifying the treatment procedure in response to the measurements of the one or more parameters.

12. The method of claim 11, wherein the one or more parameters include a temperature of the patient'"'"'s tissue.

13. The method of claim 11, wherein a feedback apparatus of the energy source automatically modifies the treatment procedure in response to the measurements of the one or more parameters.

15. The method of claim 11, wherein at least one of the one or more probes is positioned at least 1 cm lateral to the posterior sacral foramen between the lateral edge of the posterior sacral foramen and the sacroiliac joint.
