  1. The generation of heat in body tissues by the
  2. passage of high-frequency electric currents
  3. between two electrodes placed on the body,
  4. used in diathermic surgery and to relieve
  5. arthritic pain. In diathermic surgery, one
  6. electrode is very much reduced for cutting

  11. heat to cut tissues, or to coagulate and kill
  12. tissue cells, with a minimum of bleeding.
