发明名称 METHOD AND APPARATUS FOR CONTROLLED CONTRACTION OF SOFT TISSUE
摘要 An apparatus (10) and method are provided for control contraction of tissue that includes collagen fibers. The apparatus (10) includes a handpiece (12), and an electrode (14) with an electrode proximal end (16) associated with the handpiece (12). A distal end (18) of the electrode (14) has a geometry that delivers a controlled amount of energy to the tissue for a desired contraction of the collagen fibers. This is achieved while dissociation and breakdown of the collagen fibers is minimized. The handpiece (12), with electrode (14), is adapted to be introduced through an operating cannula in percutaneous applications. Additionally, an operating cannula may be included in the apparatus (10) and be attached to the handpiece (12). The apparatus (10) and method provides for a desired level of contraction of collagen soft tissue without dissociation or breakdown of collagen fibers.
