초록 ▼

A method of treating an intervertebral disc includes inserting an introducer into an intervertebral disc, inserting a catheter through the introducer and into the intervertebral disc, advancing a distal region of the catheter through a nucleus pulposus of the intervertebral disc to an annular wall of an annulus fibrosus, delivering energy to material of the intervertebral disc using an electrode disposed at the distal region of the catheter, and removing the material with the delivered energy, wherein removing material with the delivered energy reduces pressure in the intervertebral disc.

대표청구항 ▼

1. A method of treating an intervertebral disc, the method comprising: inserting an introducer into an intervertebral disc;inserting a catheter through the introducer and into the intervertebral disc;advancing a distal region of the catheter through a nucleus pulposus of the intervertebral disc to an annular wall of an annulus fibrosus;delivering energy to material of the intervertebral disc using an electrode disposed at the distal region of the catheter; andremoving the material with the delivered energy, wherein removing material with the delivered energy reduces pressure in the intervertebral disc. 2. The method of claim 1 wherein removing the material comprises removing water. 3. The method of claim 1 wherein removing the material with the delivered energy comprises ablating the material. 4. The method of claim 1 wherein removing the material comprises removing disc tissue. 5. The method of claim 1 wherein delivering energy comprises delivering thermal energy or electromagnetic energy selected from the group consisting of radiofrequency (“RF”) energy, coherent light, incoherent light, microwave, and ultrasound. 6. The method of claim 1 wherein delivering energy comprises delivering radiofrequency (“RF”) energy from a bipolar or monopolar configuration. 7. The method of claim 6 further comprising denervating at least a portion of the intervertebral disc with the delivered RF energy. 8. The method of claim 6 wherein delivering RF energy comprises delivering RF energy to the inner wall of the annulus fibrosus. 9. The method of claim 6 wherein delivering RF energy comprises delivering RF energy while the catheter is positioned at a location adjacent the inner wall of the annulus fibrosus. 10. The method of claim 6 wherein delivering RF energy comprises delivering RF energy to multiple locations in the intervertebral disc using at least the electrode. 11. The method of claim 10 wherein delivering RF energy to multiple locations comprises delivering RF energy to the multiple locations simultaneously. 12. The method of claim 10 wherein delivering RF energy to multiple locations comprises: delivering RF energy to at least a first of the multiple locations using the electrode; anddelivering RF energy to at least a second of the multiple locations using a second electrode. 13. The method of claim 10 wherein delivering RF energy to multiple locations comprises delivering RF energy to the multiple locations serially. 14. A method of treating an intervertebral disc of a body, the method comprising: inserting an introducer comprising a proximal end and a distal end into the body so that the proximal end is external to the body and the distal end is internal to the body;inserting a catheter comprising a functional element disposed at a distal region of the catheter through the introducer and into the intervertebral disc so that the functional element is positioned at a selected location of the intervertebral disc;delivering energy at the selected location of the intervertebral disc using the functional element; andremoving the material with the delivered energy, wherein removing material with the delivered energy reduces pressure in the intervertebral disc. 15. The method of claim 14 wherein the introducer is inserted into the body so that the distal end is internal to the body and internal to an annulus fibrosus of the intervertebral disc. 16. The method of claim 14 wherein the introducer is inserted into the body so that the distal end is internal to the body and adjacent to an annular opening leading to a nucleus pulposus of the intervertebral disc. 17. The method of claim 14 wherein the introducer comprises a needle and inserting the introducer comprises inserting the needle. 18. The method of claim 17 wherein the introducer comprises a needle disposed around a trocar and inserting the introducer comprises inserting the needle and trocar. 19. The method of claim 14 wherein the selected location of the intervertebral disc is selected from the group consisting of a posterior medial, a posterior lateral, an anterior lateral and an anterior medial region of an inner wall of an annulus fibrosus of the intervertebral disc or combinations thereof. 20. The method of claim 14 wherein delivering energy comprises delivering radiofrequency (“RF”) energy from an electromagnetic probe. 21. The method of claim 20 wherein the electromagnetic probe comprises an RF electrode. 22. The method of claim 21 wherein the RF electrode is monopolar or bipolar. 23. The method of claim 20 wherein delivering RF energy comprises delivering RF energy to multiple locations in the intervertebral disc using at least the electromagnetic probe. 24. The method of claim 23 wherein delivering RF energy to multiple locations comprises delivering RF energy to the multiple locations simultaneously. 25. The method of claim 24 wherein delivering RF energy to multiple locations comprises: delivering RF energy to at least a first of the multiple locations using the electromagnetic probe; anddelivering RF energy to at least a second of the multiple locations using a second electromagnetic probe.
