Abstract
An instrument and method for tissue thermotherapy including an inductive heating means to generate a vapor phase media that is used for interstitial, intraluminal, intracavity or topical tissue treatment. In one method, the vapor phase media is propagated from a probe outlet to provide a controlled vapor-to-liquid phase change in an interface with tissue to thereby apply ablative thermal energy delivery.

- 12. A method of treating spinal pain comprising introducing a vapor delivery tool into the interior of a vertebral body and delivering a vapor media wherein condensation of the vapor applies energy sufficient to ablate a basivertebral nerve.
- 14. A method of treating spinal pain comprising introducing a condensable vapor media proximate to a nerve in at least one of the interior of a disc, the interior of a vertebral body, a zygapophyseal joint and a paravertebral region wherein condensation of the vapor media applies energy to ablate said nerve.
-
19. A method of ablating a targeted tissue volume in a patient body comprising:
-
introducing an elongated probe into a patient body that includes at least one vapor delivery outlet for delivering a condensable thermal vapor to the targeted tissue; deploying at least one needle member with a temperature sensor into region proximate a periphery of the targeted tissue and monitoring temperature; delivering the condensable vapor through the probe and at least one outlet to apply ablative energy to the tissue, and controlling the applied energy in response to the monitored temperature.

-
21. The method of claim 20 wherein monitoring temperature is performed with a thermocouple temperature sensor.
-
22. The method of claim 20 wherein monitoring temperature is performed with a fiber optic temperature sensor system.
-
23. A method of ablating a targeted tissue volume in a patient body comprising:
-
providing an elongated vapor delivery tool having a working end with at least one vapor outlet for delivering a condensable vapor flow to the targeted tissue; delivering a vapor flow through the at least one outlet into the targeted tissue; and allowing a flexible member disposed around a proximal tool portion to expand when contacted by vapor flow to thereby prevent unwanted retrograde vapor flow.
-
-
24. A system for ablating a tissue within a vertebral body or intervertebral disc, the system comprising:
-
an introducer having a blunt tip; and a vapor delivery needle coupled to a fluid media source, where the vapor delivery needle is configured to apply a vaporization energy to the fluid media and where the vaporization energy exceeds a heat of vaporization of the fluid media therein to convert the fluid media to a vapor media, where the vapor delivery needle comprises at least one vapor delivery port to direct the vapor media to the tissue such that when the vapor media contacts the tissue energy transfer occurs from the vapor media to the tissue, the vapor delivery needle having a sharp tip sufficient to advance through the a vertebral body or intervertebral disc. - View Dependent Claims (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
-
-
26-1. The system of claim 24, where the needle comprises a shape memory alloy material.
-
34-2. The system of claim 24, further comprising at least one radiopaque marking on the vapor delivery needle and proximate to the vapor delivery outlets.
-
34-3. The system of claim 24, further comprising an extension member located within the vapor delivery needle, where the vapor delivery needle member comprises a deflectable working end.
