Abstract

L’invention concerne un dispositif d’assistance ou de suppléance circulatoire temporaire du cœur d’un patient, le réservoir (11) présentant une forme de poire avec une base (60) de diamètre large d1 se réduisant dans sa hauteur pour aboutir à un sommet (61) de faible diamètre d2 de telle sorte que d1 est au moins égal à sept fois d2, soit d1 > 7d2, et la portion d’admission pénétrant dans le réservoir, via un conduit d’entrée (65), orientée obliquement suivant un angle compris entre 10° et 60° par rapport à la surface du réservoir et de manière ascendante – soit vers le susdit sommet (61) - suivant un angle compris entre 10° et 50°.
