1. An ablation device, comprising:
- an elongate body having a blunt distal portion and an inner lumen configured to deliver fluid therethrough;
an emitting electrode for delivering electrical energy positioned at a distal end of the elongate body; and
a heater element configured to heat fluid within the inner lumen to a temperature greater than about 37°
C. and less than about 100°
C.;
wherein the elongate body is configured such that fluid can circulate through the elongate body and is received back at a proximal end thereof without being released into surrounding tissue.

Abstract
Devices and methods for controlling ablation therapy are provided herein. In one embodiment, an ablation device is provided that includes an elongate body having proximal and distal ends, and an inner lumen extending therethrough. The inner lumen can be configured to receive fluid therein and to deliver fluid to the distal end of the elongate body. The device can also include an ablation element positioned at a distal end of the elongate body that is configured to heat surrounding tissue, and a heater element disposed within the inner lumen adjacent to a distal end of thereof, the heater element being configured to heat fluid flowing through the inner lumen.
