An occlusion catheter for the ascending aorta capable of obstructing the blood flow within the ascending aorta without inserting through the femoral artery. The occlusion catheter is provided with a drug release aperture formed in the region, which is closer to the proximal end of the catheter tube than a balloon on the outer circumference of the distal end and which is to be located in the vicinity of the coronary ostium when the balloon is placed within the ascending aorta. The present occlusion catheter, when inserted directly into the ascending aorta in the vicinity of the heart to obstruct the blood flow therewithin, enables delivery of a cardiac muscle protective drug to the vicinity of the coronary ostium without inserting the occlusion catheter through the femoral artery in the conventional manner.

L'invention porte sur un appareil et une méthode permettant de calculer la valeur approximative du volume d'éjection systolique et le débit cardiaque d'une personne. L'appareil et la méthode font appel à la mesure de l'impédance ou de l'admittance électrique d'une partie du corps, soit le thorax. Cette partie anatomique a été choisie, car son impédance ou son admittance électrique, varie avec le temps en raison des battements réguliers du coeur. C'est la raison pour laquelle la mesure de l'admittance ou de l'impédance peut fournir des données sur l'efficacité du coeur, en tant que pompe.
