Abstract
Abstract Liposuction devices and methods and surrounding aspiration systems and methods that reduce the chances of burning and necrosis. The devices include an evacuation tube surrounding an ultrasonic probe, including the distal end thereof to define a liquefaction and/or rupture chamber. The evacuation tube has one or more openings in the distal end through which tissue such as fatty tissue may enter for rupture/liquefaction therein. Containing the ultrasonic probe within the evacuation tube avoids any possible contact with surrounding tissue other than tissue that gets drawn into the liquefaction and/or rupture chamber. The size of the liquefaction and/or rupture chamber may be variable by adjustment of the axial position of the evacuation tube relative to the ultrasonic probe, or by selection of evacuation tubes of the desired length. Various embodiments are disclosed.
