PROBE, SYSTEM, AND METHOD FOR FORMING A LESION IN A TARGET TISSUE

Abstract: a probe for forming a lesion in a target tissue includes an elongate member extending longitudinally between a proximal end and a distal end. the elongate member has an active electrode proximate the distal end for delivering ablative energy to the target tissue, and an electrically insulated section proximal of the active electrode. the active electrode includes a cooled section that is coolable by receipt of a cooling fluid delivered through the elongate member. at least a first temperature sensor is positioned external of the elongate member to measure a temperature in a heat affected zone of the target tissue. the first temperature sensor is positioned proximally of the distal end and is spaced from the cooled section.
