Abstract: The invention relates to a method for transcutaneous medical, physiotherapeutical or cosmetic treatment of the skin and subjacent organs, including a step which consists in projecting a pressurized gas onto the area that is to be treated, with the aid of a projection nozzle. Use of the method promotes penetration of the skin by oxygen-carrying fluorocarbons, enabling oversaturation of the molecules with oxygen and the creation of a massage effect.

Abstract: A liposuction device including sucking cannula member for sucking subcutaneous fat through an entry aperture, the sucking cannula member having defined therein said entry aperture and having a longitudinal axis; mechanical drive member for producing and transmitting a movement to the sucking cannula member and on which the sucking cannula member is mounted, the mechanical drive member having an entry for connecting an energy source thereto, and the movement of the sucking cannula member being a nutational movement which has a frequency ranging from 10 to 500 Hz and which comprises a vibrational component and a translational component, the vibrational component being perpendicular to the longitudinal axis of the sucking cannula member and the translational component being in line with the longitudinal axis of the sucking cannula member and having an amplitude ranging from 2 mm up to but less than 1 cm; a housing for housing the mechanical drive member; and a free space provided between the sucking cannula memb
