A device for carrying out thermal treatment in a body cavity or duct, in particular the prostate, comprising an elongate and hollow application catheter (6), heat-releasing element (19, 79), which is surrounded by an elongate housing (20, 77), a flexible and/or elastic balloon (2, 63) surrounding said housing in a liquid-tight manner. Further including an inlet passage (27, 95), an outlet (22, 54, 93) from the housing (20, 77) being arranged for the supply of a first heat-transmitting medium under pressure for expansion of the flexible balloon (2, 63) to exert, pressure on surrounding walls of said cavity or duct. Further comprising a viewing opening (5) proximal to the balloon (2, 63) for visual access to the exterior of said catheter (6) by accommodating an endoscope therein, characterized by means (30) allowing a second medium for irrigation of the endoscope lens and for cooling of the circumferential area, thereby protecting tissue surrounding said circumferential area from excessive heating. |
