A power source delivers oscillating electrical energy to an electrical conductor, such as a wire or catheter, which is coated circumferentially with a ferromagnetic material in a selected region. With high frequency electrical energy, the ferromagnetic material has a quick response in heating and cooling adjustable by the controllable power delivery. The ferromagnetic material can be used for separating tissue, coagulation, tissue destruction or achieving other desired tissue effects in numerous surgical procedures.
