Abstract

L'invention concerne une pompe à sang intravasculaire comprenant une partie d'entraînement (11) et une partie de pompage (12) solidarisée avec la partie précédente. Ces deux parties sont reliées à un cathéter (13) et peuvent être introduites dans un vaisseau sanguin (10). Le carter de pompe (15) tubulaire de la partie de pompage (12) est muni d'un dispositif de verrouillage (20) qui sépare le côté aspiration (21) du côté pression et évite ainsi un éventuel court-circuitage de l'écoulement.
