Abstract:
1. A method for treating a skin surface of a patient, comprising: (a) applying against the skin surface of a patient an instrument body with a longitudinal axis and a distal working end, said distal working end comprising a working surface that carries an abrading structure comprising a plurality of sharp elements for engaging and abrading the skin surface together with a vacuum source coupled to at least one aperture about said working surface, the abrading structure and the at least one aperture positioned within a raised outer periphery that completely circumscribes the abrading structure and the at least one aperture; (b) translating the working surface over the skin surface to thereby abrade the skin surface; and (c) contemporaneously actuating the vacuum source to thereby cause suction engagement of the skin surface against the raised outer periphery and the plurality of sharp elements of the working surface and to aspirate skin debris through the at least one aperture.
