Title (EN) IMPLANTABLE CORONARY PERFUSION PUMP
(FR) POMPE DE PERFUSION CORONAIRE IMPLANTABLE
Abstract:
(EN) A cardiac pump assist system to move blood from large arteries, such as the aorta (32), to small arteries (34) where additional blood flow is needed. The pump assist system includes a shunt (21) from the aorta (32) or other convenient source of oxygenated blood to the coronary artery (34, 36) which is supplemented by a pump. The pump is preferably of the type employing a trained muscle wrap (14) around a fluid chamber (16).
(FR) Système d'aide à pompe cardiaque destiné à déplacer le sang de grosses artères telles que l'aorte (32) à de petites artères (34) dans lesquelles un flux sanguin supplémentaire est nécessaire. Le système d'aide à pompe comprend une dérivation (21) de l'aorte (32) ou d'une autre source convenable de sang oxygéné, à l'artère coronaire (34, 36), laquelle est alimentée par une pompe. La pompe est de préférence du type employant une enveloppe musculaire entraînée (14) autour d'une chambre à fluide (16).
