Abstract
Devices and methods for fluid enhanced ablation therapy using microwave antennas are described herein that provide improved heat transfer into a target volume of tissue and improved antenna cooling compared to prior art designs. In one embodiment, fluid can be introduced into a target volume of tissue along with the delivery of therapeutic energy from a microwave antenna positioned within the target volume of tissue. The fluid can become heated by cooling the microwave antenna and, if additional heating of the fluid is desired, a heating element disposed within the microwave antenna can supplementally heat the fluid prior to introduction into the target volume of tissue.
