Device and method for medical treatment

Abstract

A device for carrying out hyperthermia in a mammalin uterus cavity, including an elongate, rigid distal section (,) and a flexible and elastic bladder (,) encompassing said distal section which, together with said bladder, is intended for insertion into said uterus cavity, further including means (,) for the supply of a heat-transmitting medium under pressure for the expansion of said bladder (,) within said uterus cavity, and heating means (,) for heating said medium, the device further having an intermediate section (,) whose distal part when inserted is positioned in a cervix canal belonging to said uterus, and a proximal section (,) for operating the device, said distal and intermediate sections (,) containing at least a central tube (,), whose distal part is surrounded by said bladder and is provided with at least one outlet (,) for said medium within said bladder, and whose intermediate part is surrounded by an axially displacable tube (,), onto whose distal end (,) the proximal end (,) of said bladder (,) is attached, characterized by means (,) for determining the axial position of the distal end (,) of said axially displacable tube and thereby also the axial position of the proximal end (,) of said bladder (,) so that the length of said bladder (,) matches the depth of a cavity subject to treatment, and means (,) for locking said tube (,) with its distal end (,) in such matching position; and the invention also involves methods of thermal treatment of human uterus cavity linings and a device for thermal treatment of mammalian body cavities or ducts, such as urethras.
