LOW PROFILE FLUID ENHANCED ABLATION THERAPY DEVICES AND METHODS
First Claim
1. An ablation device, comprising:
- an elongate body havingproximal and distal ends,an inner lumen extending longitudinally through the elongate body, andat least one outlet port formed in the elongate body configured to deliver fluid to tissue surrounding the elongate body;
at least one ablation element disposed along a length of the elongate body adjacent to the at least one outlet port and configured to deliver energy to tissue surrounding the elongate body;
at least one heating element disposed within the inner lumen of the elongate body and configured to heat fluid passing therethrough; and
a handle having proximal and distal ends, the distal end of the handle being coupled to the proximal end of the elongate body;
wherein a longitudinal axis of the elongate body extends at an angle to a longitudinal axis of the handle.

Abstract
Low profile devices and methods for delivering fluid enhanced ablation therapy are provided herein. In one embodiment, an ablation device is provided that includes an elongate body having proximal and distal ends, an inner lumen extending therethrough and at least one outlet port formed therein and configured to deliver fluid to surrounding tissue. The device can also include at least one ablation element disposed along a length of the body adjacent to the at least one outlet port and configured to deliver energy to surrounding tissue, as well as at least one heating element disposed within the inner lumen of the elongate body. The device further includes a handle having proximal and distal ends, the distal end of the handle being coupled to the proximal end of the elongate body. Further, a longitudinal axis of the elongate body extends at an angle to a longitudinal axis of the handle.

13. A method for administering fluid enhanced ablation therapy, comprising:
-
percutaneously inserting a distal end of an elongate body of an ablation device into a patient; manipulating the distal end of the elongate body within the patient using a low profile handle coupled to the proximal end of the elongate body and having a longitudinal axis that extends at an angle to a longitudinal axis of the elongate body; delivering fluid through the elongate body of the ablation device into tissue surrounding the distal end of the elongate body while simultaneously delivering energy into tissue surrounding the distal end of the elongate body. - View Dependent Claims (14, 15, 16, 17, 18, 19)
