ABSTRACT:
Systems and methods are provided for removing fatty tissue underlying a patient's epidermis (e.g., blepharoplasty, brow lifts, eyelid shortening procedures, and the like). These methods include positioning one or more active electrode(s) and one or more return electrode(s) in close proximity to a target site on an external body surface of the patient. A high frequency voltage difference is applied between the active and return electrode(s), and the active electrode(s) are translated across the external body surface to create an incision therein. The bipolar configuration controls the flow of current to within and around the distal end of the probe, which minimizes tissue necrosis and the conduction of current through unwanted paths in the patient. The residual heat from the electrical energy also provides simultaneous hemostasis of severed blood vessels, which increases visualization and improves recovery time for the patient.
