An electrode catheter and a method for assessing electrode-tissue contact and coupling are disclosed. An exemplary electrode catheter comprises an electrode adapted to apply electrical energy. A measurement circuit is adapted to measure impedance between the electrode and ground as the electrode approaches a target tissue. A processor determines a contact and coupling condition for the target tissue based at least in part on reactance of the impedance measured by the measurement circuit. In another exemplary embodiment, the electrode catheter determines the contact and coupling condition based at least in part on a phase angle of the impedance.

L'invention concerne un cathéter d'électrode et un procédé d'évaluation du couplage et du contact électrode-tissu. Un cathéter d'électrode exemplaire comprend une électrode conçue pour appliquer de l'énergie électrique. Un circuit de mesure est élaboré pour mesurer l'impédance entre l'électrode et la terre, à mesure que l'électrode s'approche d'un tissu cible. Un processeur permet de déterminer un état de contact et de couplage pour le tissu cible, ledit état reposant au moins partiellement sur la réactance de l'impédance mesurée par le circuit de mesure. Dans un autre mode de réalisation exemplaire, le cathéter d'électrode permet de déterminer l'état de contact et de couplage dépendant au moins partiellement d'un angle de phase de l'impédance.
