Abstract

Device for carrying out heat treatment, so-called hyperthermia, in a body cavity or a duct, comprising a catheter intended to be filled with heat-transferring medium and provided with an elongate front part (3) intended to be introduced into said cavity or duct and comprising a centrally positioned heat-releasing element (10), which is either surrounded by an elongate housing (9) or <u>per se</u> constitutes such housing, and a flexible and/or elastic balloon (7) surrounding said housing (9) in a liquid-tight manner, and first means (25) for expanding the balloon by the supply of heat-transferring medium, and second means (21; 93) for internal circulation of said medium through the housing (9). The device is characterized in that said second means (21; 93) is placed in series with said first means (25) and said first housing inlet (11) and comprises a first chamber (29) of variable volume which via inlet (35) and outlet (37) forms a connection between said first means (25) and said first housing inlet, said first chamber and possibly other chambers with inlets and outlets in the catheter being arranged in such a manner that the highest point of each chamber is positioned at the same level or lower than the highest point of the transition of the chamber (29) into the outlet (37).
