This invention relates generally to apparatus and methods for tightening tissue of the female genitalia by heating targeted connective tissue with radiant energy, while cooling the mucosal epithelial surface over the target tissue to protect it from the heat. Embodiments include a handle and treatment tip that has both an energy delivery element and a cooling mechanism. The handle may be a two-handed handle allowing control even while rotating and maneuvering the treatment around the genital opening. The apparatus or system may also include an integrated controller, which may confirm tissue contact without applying RF energy, based only on the temperature of the applicator and the time since the last application of energy from the applicator. 1. A method of determining if an energy-delivery element of a treatment tip for an RF energy device is in adequate communication with a tissue to be treated , without determining an electrical impedance from the tissue , the method comprising:determining the time since the energy-delivery element of the treatment tip was last activated;taking the temperature of one or more sites on the treatment tip;determining if the energy-delivery element is in contact with the tissue without applying RF energy to the tissue by comparing the temperature of the one or more sites on the treatment tip to a threshold function for the time since the treatment tip was last activated; andindicating if the treatment energy-delivery element is in contact with the tissue.2. The method of wherein the step of comparing the temperature of the one or more sites on the treatment tip to a threshold function comprises comparing to a threshold function having a ramping temperature threshold from about 30 to about 180 seconds since the energy-delivery element of the treatment tip was last activated.3. The method of claim 1 , wherein the treatment threshold ramps from about 18 degrees Celsius to just under body temperature between a finite time range since the ...
