Problems solved by technology

[0004] However, ultrasound tends to interact not only thermally but also mechanically (even at low pressure levels) with biological tissue, especially through the generation of cavitation bubbles, which are considered undesirable and unsafe for biological tissue
In addition, the scattering of focused or unfocused ultrasound energy from deep penetration can cause hot spots inside the tissue, which is a serious safety concern
Therefore, the control of the pre-heating and consequent RF heating and thus the amount, position and temperature of the treatment as a whole is insufficient or at least very complicated

Embodiment Construction

[0032] It is worth noting that in the figures, the same features can be identified by the same reference numerals. It is further noted that the figures are schematic and not necessarily to scale, and details not necessary for an understanding of the invention may have been omitted. "Upwardly", "downwardly", "beneath", "above" and similar terms relate to embodiments oriented in the figures. Furthermore, elements that are at least substantially the same or perform at least substantially the same function are denoted by the same numerals.

[0033] figure 1 RF treatment of skin tissue 1 is schematically shown having a skin surface 3 and tissue layers epidermis 1A (including stratum corneum 1B), dermis 1C and subcutaneous tissue 1D. The treatment employs a treatment system comprising RF electrodes 5 connected to an RF source 7 . The electrodes 5 are placed in contact with the skin surface 3 at a distance from each other. By applying an RF signal to the electrodes 5 , RF current w...

Abstract

A method of skin tissue (1) treatment is provided which comprises the steps of: determining a treatment zone (9) within the skin tissue below the skin surface (3); modifying an electrical conductance property of at least two first skin tissue portions (11) present on opposite sides of the treatment zone with respect to a direction parallel to the skin surface; and providing radio frequency (RF) energy to the treatment zone via said first skin tissue portions. The step of modifying said first skin tissue portions comprises decreasing electrical impedance for the radiofrequency energy, in particular increasing electrical conductance, of said first skin tissue portions relative to a second skin tissue portion present between said first skin tissue portions; and such that said first skin tissue portions extend into the skin tissue substantially from the skin surface to treatment zone. A system for skin tissue (1) treatment is also provided.

Description

technical field [0001] The present disclosure relates to the treatment of mammalian tissue, particularly human skin and subcutaneous tissue, and more particularly to thermal treatment by radio frequency energy for skin tightening and / or skin rejuvenation. Background technique [0002] It is known that human skin can become debilitated if it is heated to a temperature significantly above normal body temperature in order to deliberately cause small scale tissue damage and / or minor damage, collagen denaturation or coagulation, tissue ablation and / or necrosis young. This prompts the body to respond by repairing damaged tissue, resulting in the desired tightened and rejuvenated skin. [0003] For successful treatment, the target tissue area or treatment area should be properly treated and other tissues should be spared. Treatment areas for skin rejuvenation are generally located in the skin (epidermis and dermis) and subcutaneous tissue. For localized heating, US 7,955,262 dis...
