Title (EN) STEERABLE MICROWAVE ANTENNA SYSTEMS FOR CARDIAC ABLATION
(FR) ENSEMBLE ANTENNE MICRO-ONDES ORIENTABLE POUR L'ABLATION DE TISSUS DANS LE C×UR
Abstract:
(EN) An antenna assembly (10) has an energy propagating region (16) that is encapsulated in a material having a high dielectric constant for minimizing the loss of dissipating conductive heat patterns about the energy propagating region (16).
(FR) L'invention concerne un ensemble antenne (10) possédant une région propagatrice d'énergie (16), encapsulé dans un matériau présentant une constante diélectrique élevée permettant de limiter la perte de chaleur conductrice dissipée dans la région propagatrice d'énergie.
