Abstract:
1. A method for applying energy to a region of tissue to improve a cosmetic appearance of the tissue, the method comprising: maintaining a cooling surface at or below body temperature; placing the cooling surface against a tissue surface; advancing a plurality of electrodes at an oblique angle relative to the tissue surface into the tissue, each electrode including an active region at a distal portion thereof, such that the active region is directly below the cooling surface where the electrodes enter the tissue surface at an entry location that is spaced from the cooling surface to allow for direct cooling of an entire tissue region above the active region, where the electrodes do not pass through the cooling surface when entering the tissue surface; and applying energy to the active region of the electrodes to a region of tissue beneath the tissue surface to cause a change in the region of tissue.
