    Abstract: A catheter has a handle and a guide tube enclosing an interior bore. The guide tube has a proximal end and a distal end. A friction sleeve joins the proximal end of the guide tube to the handle. The friction sleeve extends from the handle and grips a portion of the guide tube beyond the handle. The friction sleeve forms a hand grip for the user beyond the confines of the handle. It also serves to effectively transmit torque applied at the handle to the distal end of the guide tube.

    Abstract: The invention comprises a method and apparatus for treatment of a body part. More particularly, a method and apparatus for heat treatment of tissue using a catheter inserted into a body part is described along with means for positioning the catheter and means for positioning a set of electrodes relative to a tissue sample for treatment. Still more particularly, radio frequency energy at about 400 to 500 kilohertz is used to provide heat for the tissue treatment.
