An apparatus and method are provided for control contraction of tissue
that includes collagen fibers. The apparatus includes a handpiece, and an
electrode with an electrode proximal end associated with the handpiece. A
distal end of the electrode 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, with electrode, is adapted to be
introduced through an operating cannula in percutaneous applications.
Additionally, an operating cannula may be included in the apparatus and
be attached to the handpiece. The apparatus and method provides for a
desired level of contraction of collagen soft tissue without dissociation
or breakdown of collagen fibers.
