A tissue treatment device and method comprising a plurality of spaced-apart elongated electrodes configured to receive radio frequency (RF) signal from an RF energy source and for be inserted into tissue at a plurality of depths. The elongated electrodes having a first polarity and a single flat electrode located having a second polarity. The single flat electrode is located in vicinity of the elongated electrodes and configured for contacting the tissue surface and for receiving the RF signal from the RF energy source. An actuating mechanism connected to the plurality of elongated electrodes and configured to move the elongated electrodes in two opposite directions into and out of the tissue. A controller as part of the treatment device configured to apply fractional treatment to the tissue, vary spatial density of the fractional treatment over a treatment period, operate the actuating mechanism to selectively move different elongated electrode sub-groups of the plurality of elongated electrodes according to a treatment time pattern.

Devices and methods for fractional treatment of tissue

The present invention relates to an apparatus for fractional treatment of skin tissue of a patient comprising a handpiece, at least one first electrode and at least one second electrode, arranged on a base plate for applying radio frequency energy, to at least one layer of the skin, wherein the apparatus is adapted to apply electrical energy to the skin tissue with a first pulse and a second pulse following the first pulse, with the first pulse being a low energy level pulse and the second pulse being a high energy level pulse having a higher energy level than the low energy level pulse.

Apparatus and method for non-invasive fractional treatment of skin tissue

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