Abstract: The present invention provides method and apparatus for treating tissue in a region at depth by applying optical radiation thereto of a wavelength able to reach the depth of the region and of a selected relatively low power for a duration sufficient for the radiation to effect the desired treatment while concurrently cooling tissue above the selected region to protect such tissue. Treatment may be enhanced by applying mechanical, acoustic or electrical stimulation to the region.

Abstract: A method and apparatus are provided for performing a medical procedure on a patient, for example a dermatological procedure, by use of electromagnetic radiation (EMR) having a relatively low peak power, and in particular a peak power low enough so as not to result in a phase change in the heater or chromophore absorbing radiation which would result in a significant reduction in its absorption, and of relatively long duration which is generally greater than, sometimes significantly greater than, the thermal relaxation time of the irradiated target.

Abstract: Methods and apparatus are provided for selectively heating blood vessels in a patients skin to effect a desired dermatological (medical or cosmetic) treatment. For shallow vessels, particularly plexus vessels and superficial vessels/veins, radiation is applied to the vessels involved in the treatment which includes substantial radiation in a blue band of approximately 380-450 nm. The invention also involves maximizing the radiation used for which the safety radio for the area being treated is greater then one and minimizing the radiation used for which the safety ratio is less then one. This generally involves, depending on the blood vessel involved in the treatment and the patient's skin type, using radiation in one or more of a blue, green-yellow and near infrared wavelength band and filtering out radiation at other wavelengths, including radiation between the wavelength bands used.
