    摘要： 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.

    摘要： The device and method of the present invention is a medical probe device which has an elongated guide having a longitudinal axis, and a handle and probe end, the guide defining a port at its probe end. The device also has a flexible, resilient tape stylet, movably mounted relative to said longitudinal guide for movement along the longitudinal axis, having two opposed side portions, a proximal end, a piercing end and a sharpened tip on said piercing end, and a deflector, housed within said longitudinal guide, which deflects said flexible resilient tape stylet through said port. A method of moving a stylet through an elongated guide to an outlet port is also disclosed. A method of manufacturing a flexible resilient tape stylet of the present invention is also disclosed.
