Abstract:
1. A method for treating tissue by applying energy to a region of the tissue, the method comprising: maintaining a cooling surface at a temperature that cools tissue when heated; placing the cooling surface against a tissue surface above the region of the tissue to which energy is applied; advancing a plurality of electrodes into the tissue at a second tissue surface spaced from the tissue surface placed against the cooling surface and at an angle relative to the tissue surface placed against the cooling surface, each electrode including an active region at a distal portion thereof, such that the active region is directly below the tissue placed against the cooling surface to allow for direct cooling of a tissue region above the active region of the electrodes; and applying energy to the active region of the electrodes to cause a change in the region of the tissue to which energy is applied.
