Systems and methods to control tissue heating or ablation with porous electrode structures
 Systems and methods for heating or ablating body tissue place in contact with tissue an electrode, which includes an exterior wall peripherally surrounding an interior area. A lumen conveys a medium containing ions into the interior area. At least a portion of the exterior wall of the electrode comprises a porous material sized to pass ions contained in the medium. The systems and methods transmit electrical ablation energy to the medium for ionic transport through the porous material to tissue. The systems and methods sense temperature proximal to where the electrode contacts tissue. The systems and methods control transmission of electrical ablation energy to the medium based, at least in part, upon the temperature sensed.
