Lipoplasty that employs ultrasound energy to emulsify fat via cavitation, in contrast to mechanical avulsion of fat as in SAL. Although LipoSelection® only by VASER® employs ultrasonic energy, it differs from previous-generation UAL technology that is still in use today because, in the LipoSelection procedure, fat is efficiently emulsified using the VASER System's proprietary grooved probes. Once fat is emulsified, the VASER System's unique cannulae facilitate removal of the fat emulsion while leaving other important tissues relatively intact.
