Abstract

L'invention porte sur une hémopompe rotative sans joint implantable présentant plusieurs caractéristiques qui en améliorent le fonctionnement par rapport à la technique antérieure, dont notamment: un arbre entièrement flottant sur paliers magnétiques afin d'éviter la formation de thrombus, un double cheminement du sang améliorant le rendement du moteur, un moteur sans collecteur placé dans le ventricule gauche indépendamment de l'impulseur, un impulseur à flux axial/radial monté sur l'axe du moteur et placé dans une partie du boîtier extérieure au coeur, et des moyens permettant de pulser le flux sortant de la pompe.
