Abstract
Systems and methods for heating or ablating body tissue use a porous electrode structure in which the porous section of the structure occupies more of the distal region of the structure than the proximal region. In a preferred embodiment, at least 1/3rd of the proximal region of the structure is free of pores. The porous section can be either ultraporous or microporous.
