title: Thermomagnetic surgery for renal cancer.
abstract: Thermomagnetic surgery is a technique that uses hysteresis heating of ferromagnetic materials to produce focally controlled temperatures within solid organs or tumors to cause coagulation necrosis. The degree of heating of a neoplasm is controlled by manipulating the power of the electromagnetic coil system through temperature monitoring. This effectively limits the region of destruction to the disease process and thereby avoids damage to surrounding structures. If the ferromagnetic material is delivered by an arterial route to the tumor or organ additional beneficial effect of ischemic necrosis of tissue may be achieved. This new technique is applicable to selected cases of human cancer. Exposure in the electromagnetic fields or use of the ferromagnetic material in experimental animals has produced no ill effects.
