ABSTRACT:
An apparatus, system, and method for treating body tissue using controlled application of heat includes a control unit providing electrical power to a bipolar electrode positioned within an expandable member filled with conductive fluid. Electrical power applied to the bipolar electrode by the control unit causes current to pass from the active electrode, into the conductive fluid, and to the return electrode, thereby heating the conductive fluid. The temperature of the conductive fluid is monitored by the control unit, and power is increased and decreased in accordance with a comparison of the monitored temperature against the desired temperature range. The control unit also includes a pressure sensor for regulating the pressure in the bladder. Pressure and temperature displays and other operator controls are located on the control unit.
