Abstract
Methods and apparatus are provided for cauterizing predetermined volumes of abnormal biological tissue using a user selectable or adjustable energy applicator including two or more electrodes having electrode parameters configured to cause cauterization of predetermined volumes when operated in a bipolar mode. The energy applicators are employed with a control device that couples the energy applicators to a power source and includes circuitry for interrupting activation of the energy applicator when the current between the two or more electrodes decreases more than a predetermined amount from the current sensed upon initial activation of the energy applicator.
