A device for supply of heat to body tissue, comprising a heating device (10) and a first temperature transducer (19) 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 (19) 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).

L'invention concerne un procédé et un dispositif permettant de fournir de la chaleur aux tissus de l'organisme. Ce dispositif comprend un dispositif chauffant (10) et un premier capteur de température (19) pouvant être inséré dans le tissu de l'organisme. Le dispositif chauffant (10) est connecté à un bloc d'alimentation (13) commandé par une unité de commande (14) via un cathéter de traitement (12) pouvant être inséré dans une cavité de l'organisme. Ledit premier capteur de température (19) est connecté par liaison active à l'unité de commande (14) qui, à son tour, est connectée par liaison active à un premier moyen mémoire (15) destiné au stockage de données correspondant à la survie des cellules en fonction de leur température. Un dispositif d'entrée (16) est connecté par liaison active à l'unité de commande (14) afin de permettre l'entrée de données, telles que le volume/poids souhaités du tissu de l'organisme auquel la chaleur doit être appliquée jusqu'à la mort des cellules de ce tissu. L'unité de commande (14) est connectée par liaison active à un instrument de calcul (17) permettant de déterminer le volume et le poids d'un tel tissu dont les cellules sont mortes, en fonction de la température du tissu situé à une certaine distance du dispositif chauffant (10).
