ABSTRACT:
A device is described which allows simultaneous application of suction or vacuum for evacuation of fat with application of energy to the fat inside an opening in a cannula. A pair of electrodes is situated within the cavity of the cannula just under the surface of cannula tip opening(s) or as part of the walls of such openings. The electrodes are spaced to allow coagulation of fat entering the cannula. Irrigation may be applied in a continuous or discontinuous or intermittent stream within the cannula to cool the tip and facilitate removal of suctioned tissue and prevent buildup of debris on electrodes. A method for using the cannula to remove adipose tissue or fat destroyed by the energy application through the use of suction with mechanical motion of the cannula, with energy application and optionally with the use of irrigation is also disclosed.
