Claim 0:
1. An apparatus for treatment of skin tissue of a patient, the apparatus comprising:
a handpiece with a housing;
at least one first electrode and at least one second electrode located on a distal end of the handpiece;
an energy source, which is connected to said at least one first and said at least one second electrode, wherein 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;
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;
wherein the apparatus is configured to apply an ablative radio frequency (RF) energy to the skin tissue,
wherein the vacuum chamber is configured to exert a negative pressure force on a surface of the skin tissue towards the at least one first electrode and the at least one second electrode, when the at least one first electrode and the at least one second electrode are placed in proximity of or are touching the surface of the tissue, and
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.
