Abstract

L'invention concerne un dispositif d'assistance circulatoire mécanique temporaire pour le cœur, comportant une chambre de remplissage sanguine (C) à volume variable dans laquelle est destinée à transiter le sang du patient, ladite chambre étant munie d'un conduit d'admission (A) destiné à être relié à une canule d'admission du sang et d'un conduit d'éjection (E) destiné à être relié à une canule d'éjection du sang, se caractérisant par le fait que le volume de la chambre de remplissage (C) varie sous l'effet de l'oscillation d'une membrane (110), et par le fait qu'un actionneur linéaire (12), dont le déplacement est commandé par un système d'asservissement tenant compte en temps réel des besoins physiologiques du patient et de l'état hémodynamique dudit patient, permet de faire osciller la membrane (110) de façon à générer un débit sanguin pulsé systolo-diastolique.
