One conduit has a cooling distal section for the freezing tissue with one or more miniature opposite thermoelectrical effect or Peltiers element zubzero temperatures, can also be referred to herein as cooling (MPC) unit of micro- Pelletier or electrode. MPC units can have as on an inflatable or balloon member of an inner cavity containing fluid for a radiator or the outer surface of a head electrode shell wall. Every MPC units have a hot temper junction and a cold junction, and temperature is adjusted by the radiator and one voltage/circuit for being applied to MPC units. About 70 degrees Celsius of a temperature difference can be obtained between cold and hot junction for extreme cooling, especially wherein MPC units include the semiconductor material with high Pelletier high-efficient altogether. MPC units are prevented the access of unintentional electric current by still electrically-insulative material external skin of heat transfer by MPC units.
