Abstract

Un système d'assistance cardiaque comprend un cathéter et une pompe escamotable/expansible reliée à une extrémité distale du cathéter. La pompe comprend un conduit flexible externe, un premier clapet de non-retour mobile fixé au conduit flexible externe autour du périmètre du premier clapet de non-retour mobile, et un second clapet de non-retour mobile, espacé du premier clapet de non-retour mobile et en série avec celui-ci, fixé au conduit flexible externe autour du périmètre du second clapet de non-retour mobile. Un système d'entraînement positionné à distance est relié au cathéter. Un premier actionneur et un second actionneur sont reliés fonctionnellement au système d'entraînement pour transférer un mouvement linéaire du système d'entraînement au premier clapet de non-retour mobile et au second clapet de non-retour mobile, respectivement.
