Abstract
The invention provides improved methods and devices for heating a thermally conductive fluid within an internal body organ to thermally ablate or necrose the body organ. In an exemplary embodiment, the invention provides a thermal ablation device having an elongate member with a proximal end and a distal end. A heating apparatus is provided near the distal end of the elongate member which is constructed to heat a thermally conductive fluid without substantial direct heating of the heating apparatus. A fluid circulator is provided near the heating apparatus which circulates the thermally conductive fluid past the heating apparatus.
