ABSTRACT:
A method and device for medical treatment of a tissue mass. The method comprises introducing a catheter along a body duct to a zone adjacent to the target tissue to be treated. A flexible stylet comprising a radiofrequency electrode partially enclosed within a non-conductive sleeve is moved from the catheter through a catheter port in the side wall of the catheter and through surrounding tissue into a target tissue to be treated. An outward force is exerted on the wall of the body duct by means of an inflatable balloon attached to the catheter and heat is generated in the target tissue by passing electrode current from the exposed area of the electrode into the target tissue.
