An apparatus for effecting hyperthermia in a narrow body cavity or duct comprising: a disposable first part (1) comprising an elongate distal section (5) intended to be inserted into said cavity or duct comprising a centrally located, heat-releasing element (22), which is either surrounded by an elongate housing (24) or is itself constituted by an elongate housing, and a flexible and/or elastic enclosure (23) surrounding said housing in a liquid-tight manner, further including means for supplying energy to the heat-releasing element (22) and an axially operating first inlet (135) at the proximal part of the housing, an outlet (133) from the housing being arranged for the supply of heat-transmitting medium under pressure for expansion of the flexible enclosure (23) to accommodate and to exert a controlled pressure on surrounding walls of said cavity or duct, a second inlet (131) to the housing (24), and medium-actuating means (13, 19) for said expansion of the flexible enclosure (23) and for internal circulation of said medium through the housing (24); and a permanent non-disposable second part (51) comprising drive means (55, 75) for said means (13, 19) for expansion and for internal circulation, and connecting means (43, 59; 41, 81) for releasably interconnecting said drive means (55, 75) and said means (13, 19) for expansion and internal circulation. |
