Abstract

A first probe and a second probe arc coupled to a source of electrical energy. The first probe and the second probe arc each configured to create a lesion when inserted into tissue and electrical energy is applied from the source of electrical energy. A first switch is coupled to the first probe and couples the first probe to ground when in a closed state. A second switch is coupled to the second probe and couples the second probe to ground when in a closed state. A control system is configured to receive an indication of a first parameter at the first probe and control the first switch based on the first parameter. The control system is also configured to receive an indication of a second parameter at the second probe and control the second switch based on the second parameter.
