The invention is practiced by introducing a catheter (10) into the left ventricle of the heart. Deployment of an intraventricular pump assembly (12) from the end of catheter (10) is carried out by pushing holding device (24) in direction of the arrow (26). The tubes (20) of the intraventricular pump assembly (16) swing outward to protrude from hub (18). The first intraventricular pump (16) has a resilient bulb (30) attached to the hub (18). The tubes (20) are then self-anchored the myocardium such that they can act to inject blood into the myocardial wall from the ventricle.
L'invention est mise en pratique par l'introduction d'un cathéter (10) dans le ventricule gauche du coeur. Le déploiement d'un ensemble pompe intraventriculaire (12) par l'extrémité du cathéter (10) est effectuée par poussée d'un dispositif de maintien (24) en direction de la flèche (26). Les tubes (20) de l'ensemble pompe intraventriculaire (16) basculent à l'extérieur pour dépasser d'un moyeu (18). La première pompe intraventriculaire (16) présente un bulbe résiliant (30) fixé au moyeu (18). Les tubes (20) s'ancrent ensuite automatiquement au myocarde de sorte qu'ils peuvent injecter du sang dans la paroi myocardique à partir du ventricule.
