Patent ID: 11963710

Abstract:
The present disclosure relates to an apparatus (1) for fractional treatment of skin tissue of a patient. The apparatus (1) comprises a handpiece with a housing, at least one first electrode (11) and at least one second electrode (15) located on a distal end of the handpiece and an energy source, which is connected to said at least one first (11) and said at least one second (15) electrode. The apparatus (1) is adapted for applying radio frequency (RF) energy to the tissue. The at least one second electrode (15) is arranged on a base plate (13) and the at least one first electrode (11) is or comprises a pin or a needle (11), in particular a microneedle, which penetrates the base plate (13) through a through hole (17). The apparatus (1) further comprises a vacuum chamber (9) behind the base plate (13) and inside of the housing of the handpiece, which is in fluid communication with the at least one through hole (17) provided in the base plate (13) for exerting attraction onto a surface (33) of the skin tissue towards the at least one first electrode (11) and towards the at least one second electrode (15), when the first electrode (11) and the at least one second electrode (15) is placed in proximity of or is touching the surface (33) of the tissue.
