Abstract

Claims (46)

1. A treatment procedure for treating bodily tissue having one or more treatment sites, comprising the steps of:

(i) percutaneously inserting a tissue removal apparatus into at least one of said one or more treatment sites;

(ii) activating said tissue removal apparatus to remove tissue;

(iii) percutaneously inserting an energy delivery apparatus into at least one of said one or more treatment sites; and

(iv) delivering energy via said energy delivery apparatus;

wherein said energy delivery apparatus comprises at least two separate probes independently positionable relative to one another and wherein the step of inserting the probes comprises inserting said at least two probes into spaced apart treatment sites and wherein said energy is delivered in a bipolar fashion between said at least two probes.

2. The treatment procedure of claim 1 , wherein said bodily tissue comprises an intervertebral disc.

3. The treatment procedure of claim 1 , wherein said energy delivery apparatus further comprises a means of cooling said probes.

4. The treatment procedure of claim 1 , further comprising the steps of:

(v) measuring a parameter selected from the group consisting of a temperature and an electrical impedance; and

(vi) controlling the delivery of energy in response to a measured parameter.

5. The treatment procedure of claim 1 , wherein at least one of said energy delivery apparatus and said tissue removal apparatus comprises a marker selected from the group consisting of a radiopaque marker, a visual marker and a tactile marker.

6. The treatment procedure of claim 1 , further comprising a step of measuring a tissue parameter in order to determine the efficacy of said treatment procedure.

7. The treatment procedure of claim 1 , further comprising the steps of:

(v) measuring the pressure exerted by said bodily tissue on said tissue removal apparatus; and

(vi) controlling the removal of tissue in response to a measured pressure.

8. The treatment procedure of claim 3 , wherein said means of cooling said probes comprises means for internally cooling said probes.

9. A treatment procedure for treating bodily tissue having one or more treatment sites, comprising the steps of:

(i) percutaneously inserting a tissue removal apparatus into at least one of said one or more treatment sites;

(ii) activating said tissue removal apparatus to remove tissue;

(iii) percutaneously inserting an energy delivery apparatus having at least two separate probes independently positionable relative to one another into at least one of said one or more treatment sites by inserting said at least two probes into spaced apart treatment sites; and

(iv) delivering energy via said energy delivery apparatus in a bipolar fashion between said at least two probes;

wherein said tissue removal apparatus comprises a mechanical conveyance apparatus and wherein said mechanical conveyance apparatus is located within a sheath and is structured to mechanically convey material to a location external to a patient's body without suctioning the material to the location.

10. The treatment procedure of claim 9 , wherein said bodily tissue comprises an intervertebral disc.

11. The treatment procedure of claim 9 , further comprising the steps of:

(v) measuring a parameter selected from the group consisting of a temperature and an electrical impedance; and

(vi) controlling the delivery of energy in response to a measured parameter.

12. The treatment procedure of claim 9 , wherein at least one of said energy delivery apparatus and said tissue removal apparatus comprises a marker selected from the group consisting of a radiopaque marker, a visual marker and a tactile marker.

13. The treatment procedure of claim 9 , further comprising a step of measuring a tissue parameter in order to determine the efficacy of said treatment procedure.

14. The treatment procedure of claim 9 , further comprising the steps of:

(v) measuring the pressure exerted by said bodily tissue on said tissue removal apparatus; and

(vi) controlling the removal of tissue in response to a measured pressure.

15. A treatment procedure for treating an intervertebral disc having one or more treatment sites, comprising the steps of:

(i) percutaneously inserting a first apparatus structured to remove material into at least one of said one or more treatment sites of said intervertebral disc;

(ii) activating said first apparatus to remove tissue from said intervertebral disc;

(iii) percutaneously inserting a second apparatus having at least two separate probes independently positionable relative to one another structured to deliver energy into at least one of said one or more treatment sites of said intervertebral disc inserting said at least two probes into spaced apart treatment sites; and

(iv) delivering energy via said second apparatus in a bipolar fashion between said at least two probes to said intervertebral disc;

wherein the tissue is removed via a mechanical conveyance without suctioning.

16. The treatment procedure of claim 15 , further comprising the steps of:

(v) measuring a parameter selected from the group consisting of a temperature and an electrical impedance; and

(vi) controlling the delivery of energy in response to a measured parameter.

17. The treatment procedure of claim 15 , wherein at least one of said first apparatus and said second apparatus comprises a marker selected from the group consisting of a radiopaque marker, a visual marker and a tactile marker.

18. The treatment procedure of claim 15 , further comprising a step of measuring a tissue parameter in order to determine the efficacy of said treatment procedure.

19. The treatment procedure of claim 15 , further comprising the steps of:

(v) measuring the pressure exerted by said bodily tissue on said first apparatus; and

(vi) controlling the removal of tissue in response to a measured pressure.
