Abstract

L'invention concerne une pompe à sang axiale constituée d'une structure corps fixe et d'un rotor monté rotatif dans ladite structure autour d'un axe de rotation, de façon à produire un flux de sang suivant ledit axe. Le rotor comprend une chemise généralement cylindrique, centrée sur l'axe de rotation; une pluralité d'aubes de rotor, allongées vers l'intérieur depuis la surface interne de la chemise de façon à s'entrecouper au niveau de l'axe de rotation; et un moyeu central, centré sur l'axe de rotation et formé par l'intersection des aubes. La pompe comporte également un moteur électrique disposé à la fois dans la chemise et dans la structure corps. Plus spécifiquement, le moteur électrique comprend une série de bobinages, enfermés dans la structure corps fixe, et une série d'aimants permanents allongés axialement, incorporés à la chemise. La pompe peut être utilisée dans un appareil d'assistance ventriculaire implantable. La géométrie axiale à rotor fermé de la pompe, associée au petit diamètre du moyeu central, accroît le volume de sang que la pompe est capable de contenir et donc de pomper.
