DEVICES AND METHODS FOR SHAPING THERAPY IN FLUID ENHANCED ABLATION
First Claim
1. A method for forming an ablation treatment volume in tissue having a desired shape, comprising:
- delivering therapeutic energy to tissue to form an ablation treatment volume in the tissue; and
simultaneously delivering a first fluid and a second fluid to the tissue, the first and second fluids convecting the therapeutic energy in a desired direction such that the ablation treatment volume has a desired shape.

Abstract
Devices and methods for shaping an ablation treatment volume formed in fluid enhanced ablation therapy are provided. The devices and methods disclosed herein utilize the interaction of fluids to create ablation treatment volumes having a variety of shapes. In one embodiment, a method for forming an ablation treatment volume having a desired shape includes delivering therapeutic energy to tissue to form an ablation treatment volume and simultaneously delivering a first fluid and a second fluid to the tissue. The first and second fluids can convect the therapeutic energy in a desired direction such that the ablation treatment volume has a desired shape.

10. A method for shaping therapeutic energy delivered to tissue comprising:
-
positioning a first elongate body in a patient'"'"'s body at a first location, the first elongate body having an inner lumen extending therethrough, at least one outlet port formed therein, at least one ablation element disposed along a length thereof, and at least one heater element disposed within the inner lumen; positioning a second elongate body in a patient'"'"'s body at a second location, the second elongate body having an inner lumen extending therethrough and at least one outlet port formed therein; and simultaneously delivering a first fluid from the first elongate body and a second fluid from the second elongate body such that the first and second fluids interact to shape an ablation treatment volume. - View Dependent Claims (11, 12, 13, 14)
