Abstract

L'invention concerne des techniques, des procédés et des algorithmes de positionnement de pompes à sang de cathéter. Dans un mode de réalisation, des mesures de capteur de pression sont utilisées pour déterminer la distance à la valve aortique et au ventricule gauche. Un emplacement de positionnement optimal peut être déterminé sur la base des mesures de capteur de pression. La pompe à sang de cathéter peut ensuite être positionnée de manière optimale pour localiser l'entrée dans le ventricule et la sortie dans l'aorte.
