Abstract

Methods of treating the sacroiliac region of a patient'"'"'s body by delivering energy are described. In some embodiments, the method comprises the steps of: positioning one elongated probe comprising at least one energy delivery device within a sacroiliac joint of the body; and delivering radiofrequency energy through the elongated probe. In some embodiments, the delivery of energy results in the creation of a lesion. In further embodiments, energy may be delivered substantially along a long axis of the sacroiliac joint. In yet further embodiments, at least one energy delivery device may be positioned adjacent a sacroiliac joint and energy may be delivered so as to create a lesion at least partially within the joint.

Claims

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

positioning one elongated probe comprising at least one energy delivery device within a sacroiliac joint of the body; and

delivering radiofrequency energy through the elongated probe.

2. The method of claim 1, wherein energy is delivered sufficient to alter the function of at least one neural structure innervating the sacroiliac joint.

3. The method of claim 1, wherein the step of delivering radiofrequency energy comprises delivering energy sufficient to create a strip lesion within the sacroiliac joint.

4. The method of claim 3, wherein the strip lesion has its longest dimension parallel to a longitudinal axis of the elongated probe.

5. The method of claim 3, wherein the strip lesion is created while the at least one energy delivery device remains in a substantially static position.

6. The method of claim 1, wherein the step of delivering radiofrequency energy comprises delivering energy along a substantial part of a long axis of the sacroiliac joint.

7. The method of claim 1, wherein energy is delivered in a configuration selected from the group consisting of a monopolar configuration, a bipolar configuration and a triphasic configuration.

8. The method of claim 1, wherein the at least one energy delivery device is actively or passively cooled.

9. The method of claim 1, wherein the radiofrequency energy is delivered in a series of amplitude or frequency modulated pulses.

10. The method of claim 1, wherein the at least one energy delivery device comprises a resistive heater, whereby thermal energy may be delivered to the sacroiliac joint.

11. The method of claim 1, wherein the step of positioning the elongated probe comprises positioning the elongated probe within an intra-articular space of the sacroiliac joint.

12. The method of claim 1, wherein the step of positioning the elongated probe comprises positioning the elongated probe within a region of cartilage of the sacroiliac joint.

13. The method of claim 1, wherein the step of positioning the elongated probe comprises inserting the elongated probe through a synovial capsule of the sacroiliac joint.

14. The method of claim 1, wherein the step of positioning the elongated probe comprises positioning the elongated probe adjacent to at least one of the anterior and posterior margins of the sacroiliac joint.

15. The method of claim 1, wherein the step of positioning the elongated probe comprises a step of using one or more introducers to penetrate into the sacroiliac joint.

16. The method of claim 15, wherein at least one of the one or more introducers are curved.

17. The method of claim 1, wherein the step of positioning the elongated probe is facilitated using an imaging modality.

18. The method of claim 17, wherein the step of positioning the elongated probe comprises visualizing at least one radiopaque marker to assess a position of the at least one energy deliver device within the body.
