Abstract
L'INVENTION CONCERNE UN DISPOSITIF DE THERAPIE LOCALISEE PAR DIATHERMIE ET IRRADIATION SIMULTANEE. LE DISPOSITIF COMPORTE UN CONDUCTEUR ELECTRIQUE ANNULAIRE 3 CONSTITUE D'UNE TRESSE D'ACIER INOXYDABLE ET DES MOYENS 5 D'ISOLATION ELECTRIQUE SITUES A PROXIMITE IMMEDIATE DE CE CONDUCTEUR 3 ET EN BUTEE CONTRE CE DERNIER. AINSI, LE TRAITEMENT DE DIATHERMIE PAR LE COURANT ELECTRIQUE PASSANT DANS LE CONDUCTEUR 3 EST LOCALISE AU TRONCON DU CONDUCTEUR ANNULAIRE 3 QUI N'EST PAS ISOLE. AU MOINS UN ISOTOPE RADIOACTIF 7 PEUT ETRE PLACE DANS LE TRONCON NON ISOLE DU CONDUCTEUR ELECTRIQUE ANNULAIRE 3 AFIN DE PERMETTRE UNE THERAPIE LOCALISEE SIMULTANEE PAR DIATHERMIE ET IRRADIATION. DOMAINE D'APPLICATION: TRAITEMENT DE TUMEURS MALIGNES.THE INVENTION RELATES TO A THERAPY DEVICE LOCATED BY DIATHERMIA AND SIMULTANEOUS IRRADIATION. THE DEVICE INCLUDES AN ANNULAR ELECTRIC CONDUCTOR 3 CONSTITUTES A STAINLESS STEEL BRAID AND ELECTRICAL INSULATION 5 MEANS LOCATED IN IMMEDIATE PROXIMITY OF THIS CONDUCTOR 3 AND IN STOP AGAINST THE LATTER. THUS, THE TREATMENT OF DIATHERMIA BY THE ELECTRIC CURRENT PASSING THROUGH CONDUCTOR 3 IS LOCATED AT THE TRUNK OF ANNULAR CONDUCTOR 3 WHICH IS NOT ISOLATED. AT LEAST ONE RADIOACTIVE ISOTOPE 7 MAY BE PLACED IN THE UNINSULATED TRUNK OF THE ANNULAR ELECTRIC CONDUCTOR 3 IN ORDER TO ALLOW SIMULTANEOUS LOCALIZED THERAPY BY DIATHERMIA AND IRRADIATION. FIELD OF APPLICATION: TREATMENT OF MALIGNANT TUMORS.
