1. A method for treatment of target tissue or structures with a source of pulsed electromagnetic energy with thermal quenching of adjacent or surface tissue, the method comprising the following steps:

  • (A) Generating pulsed energy from an energy source;

    (B) Delivering the pulsed energy to the target tissue or structures with a delivery device;

    (C) Irradiating the target tissue or structures with the pulsed energy to cause selective thermally mediated treatment of the target tissue or structures such that there is minimal absorption of energy in surface tissue and adjacent tissue and selective absorption of energy in target tissue, and such that surface tissue remains at a temperature below the threshold for damage temperature during irradiation; and

    (D) Thermal quenching of tissue adjacent or overlying the treated target tissue with cooling times of about 30 milliseconds subsequent to step B with delay times between about 0 to about 15 milliseconds to prevent undesired temperature rise in adjacent or overlying tissue due to conduction of heat from the treated target tissue into the adjacent or overlying tissue.
