Abstract
An attachment for an endoscope for the treatment of deep tissue tumors using RF hyperthermia is disclosed. In one embodiment, electrodes are adapted to straddle or penetrate a tumor in order to confine the interstitial current heating and are detachably fitted to the distal end of the endoscope. The electrodes are electrically coupled to an RF generating power source by means of wires that extend along the outer surface of the tubular body of the endoscope and are detachably mounted thereto.
