1. A method of treating tissue in a uterus, comprising the steps of:
providing a moisture permeable electrode member comprising an array of electrodes;
positioning at least a portion of the array of electrodes in contact with tissue in a region of a tubal ostium of a fallopian tube;
delivering RF energy to the electrodes, causing the tissue to release liquid; and
applying suction through the moisture permeable electrode member to draw released liquid from the uterus, the suction substantially preventing formation of a low-impedance liquid layer around the electrodes.
