Claim 13:
14. A method for treatment of skin tissue of a patient, the method comprising:
Providing: a handpiece comprising a housing; at least one first electrode and at least one second electrode located on a distal end of the handpiece, the at least one second electrode is arranged on an apertured base plate and the at least one first electrode distally penetrates the apertured base plate through an aperture in the apertured base plate; an energy source, which is connected to said at least one first and said at least one second electrode; and a vacuum chamber within the housing of the handpiece, the vacuum chamber being in fluid communication with at least one aperture provided in the apertured base plate;
placing the handpiece of in close proximity or touching a surface of the skin tissue,
pulling, by the vacuum chamber, the skin tissue towards the at least one first electrode and the at least one second electrode,
supplying the at least one first and the at least one second electrodes with electrical energy; and
applying the electrical energy to the skin tissue,
wherein
wherein said at least one first electrode is in the form of a pin or needle having a flat and blunt conductive distal end that does not penetrate into the skin surface when no electrical energy is supplied and configured to ablate the skin tissue in contact with and drill a hole in the skin tissue when the ablative radio frequency energy is applied.
