ABSTRACT:
A liposuction cannula constructed of a cannular tube having a proximal open end attachable to a vacuum source and a plurality of apertures disposed laterally through at least one longitudinal segment of the tube. The apertures preferably are situated substantially uniformly about the tube and have a cross-sectional area of about 7.6.times.10.sup.-4 to about 3.0.times.10.sup.-3 inch. Inside diameter of the tube is preferably from about 1.2 mm to about 2.2 mm to thereby provide a cannula whose size causes a relatively minimal invasive action through individual incisions through skin to sites of lipid-containing tissue. A method of performing liposuction includes tumescent delivery of a local anesthetic and vasoconstrictor medication to an adipose tissue site and thereafter providing the cannula defined above to the site. The vacuum source is activated and the cannula is moved longitudinally forward and backward within the tissue site. By so doing, the apertures additionally function as a rasp by such longitudinal movement to facilitate disassociation of the lipid from the surrounding tissue.
