Abstract
A device for supply of heat to body tissue, comprising a heating device (10) and a first temperature transducer (11) which is insertable in the body tissue, the heating device (10) being connected with an energy supply unit (13) governed by a control unit (14) via a catheter for treatment (12) which is insertable in a body cavity and said first temperature transducer (11) being operatively connected to the control unit (14). The control unit (14) is operatively connected with first memory means (15) for storage of data corresponding to the survival of cells as a function of cell temperature. An input device (16) is operatively connected to control unit (14) to enter data such as desired volume/weight of body tissue to which heat is to be supplied to such an extent that the cells of the tissue die, and the control unit (14) being operatively connected to calculation instrument (17) for determining volume and weight of such body tissue whose cells have died as a function of temperature in the tissue at a certain distance from heating device (10).
