TREATMENT SYSTEMS, METHODS, AND APPARATUSES FOR ALTERING THE APPEARANCE OF SKIN

摘要

Systems and methods that enable tissue cooling and delivery of energy for altering tissue are described herein. Aspects of the disclosure are directed to, for example, heating tissue at treatment zones to ablate, denature, reorganize, coagulate, or otherwise alter the tissue to affect the cosmetic appearance of the patient. The method can include, for example, removing heat from the target region of the human subject before, during, and/or after energy delivery to cool tissue to a temperature below normal body temperature to inhibit pain.

主权项

1. A method for affecting dermal tissue of a subject with skin, comprising:
applying an applicator to an external surface of the subject's skin; cooling the external surface using the applicator to cool bulk dermal tissue in the skin to a bulk analgesic temperature equal to or lower than about 10° C. so as to provide a numbing effect to the bulk dermal tissue; and sequentially delivering energy from the applicator to heat microscopic treatment zones within the bulk dermal tissue such that the microscopic treatment zones are sequentially heated to at least about 50° C. while the numbing effect inhibits pain in the bulk dermal tissue and the heated microscopic treatment zones.
