Abstract: Improved electrode assemblies for treating a tissue region at or near a sphincter comprise a support structure and an electrode carried by the support structure for advancement in a path to penetrate the tissue region. In one arrangement, the electrode has a non-cylindrical cross section selected to resist deflection when advanced to penetrate the tissue region. In another arrangement, the electrode includes a tissue stop to resist tissue penetration beyond a selected depth. In another arrangement, the electrode includes a proximal portion formed from a first material and a distal tissue penetrating portion formed of a second material different than the first material. The first material can comprise, e.g., stainless steel, and the second material can comprise, e.g., nickel titanium.

Abstract: 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.

Abstract: A medical probe for the treatment by radio frequency ablation of tissue in a human comprising an elongate probe member having proximal and distal extremities. The elongate probe member has a longitudinal axis and at least one passage extending from the proximal extremity to the distal extremity. A guide cannula is mounted in the at least one passage of the elongate probe member and has proximal and distal extremities with the distal extremity of the guide cannula being in the vicinity of the distal extremity of the elongate probe member. The guide cannula has an opening in the distal extremity and a lumen extending from the proximal extremity to the opening in the distal extremity. A stylet is slidably disposed in the lumen of the guide cannula and includes a radio frequency electrode having a distal portion and a layer of insulating material disposed around the radio frequency so that at least the distal portion is exposed. A handle is coupled to the proximal extremity of the elongate probe member. The distal extremity of he guide cannula has a bendable distal portion. The handle includes a first actuator for causing the distal portion of the guide cannula to bend at an angle to the longitudinal axis so that the opening faces the tissue and a second actuator secured to the stylet for advancing the radio frequency electrode and the layer of insulating material from the opening in the guide cannula into the tissue.
