Water-assisted Liposuction (WAL)
WAL uses a thin fan-shaped water beam, which loosens the structure of the fat tissue, so that it can be removed by a special cannula. During the liposuction the water is continually added and almost immediately aspirated via the same cannula. WAL requires less infiltration solution and produces less immediate edema from the tumescent fluid.
