A method for removing fatty tissue from a patient includes the steps of inserting an aspirating cannula into the fatty tissue of the body, removing the fatty tissue in the vicinity of an internal layer of the patient's skin and traumatizing the skin adjacent to the area from which fatty tissue is removed. The method is generally carried out by means of an improved aspirating cannula which includes a longitudinally extending tubular member, an opening at one end thereof and a plurality of integrally formed projecting members surrounding the openings. The projecting members are relatively narrow and thin and extend radially outwardly and longitudinally. An annular member which is angularly disposed with respect to the longitudinally projecting member and of similar width and thickness connects the longitudinal members and is effective in breaking down fat tissue without cutting blood vessels or nerves during reciprocal movements of the cannula. The annular member is effective for traumatizing the internal layer of skin adjacent to the area where fatty tissue is removed and causes the skin to shrink in that area.
