Abstract
A method for preparing a cooled radiofrequency probe for use to treat tissue of a patient's body includes providing a plurality of cooled radiofrequency probes. Each of the plurality of cooled radiofrequency probes includes an elongate member with a distal region and a proximal region. The distal regions each have an electrically and thermally-conductive energy delivery device for delivering one of electrical and radiofrequency energy to the patient's body. The electrically and thermally-conductive energy delivery devices each have one or more internal lumens for circulating a cooling fluid therethrough and an electrically and thermally-conductive protrusion having a temperature sensing element. The temperature sensing elements of each protrusion extends from a distal end of the energy delivery device. Further, each of the temperature sensing elements has a different length that extends from the distal end of the energy delivery device. The method further includes determining at least one of a desired lesion size or a desired rate of power delivery required to treat the tissue. As such, the method includes selecting one of the probes from the plurality of cooled radiofrequency prob…
