Abstract

L'invention porte sur des dispositifs, sur des systèmes et sur des procédés de mesure de conductance de tissu parallèle, de sections transversales luminales, de vitesse de fluide et/ou de détermination de vulnérabilité de plaque à l'aide de la température. Dans au moins un mode de réalisation d'un procédé pour obtenir la conductance de tissu parallèle, le procédé comprend les étapes d'insertion d'au moins une partie d'un dispositif de détection dans un organe luminal, d'application d'un courant à celui-ci, d'obtention d'une mesure de la température endogène, d'injection d'une solution d'une conductivité connue dans l'organe luminal, de détection d'un changement de température indicatif du fluide à l'intérieur de l'organe luminal, de mesure d'une conductance de sortie et de calcul d'une conductance de tissu parallèle sur la base de la conductance de sortie et de la conductivité de la solution injectée.
