Abstract:
(EN) The present invention relates to membranes specially developed for use in chambers for artificial circulatory assistance, which may be used principally in cardiovascular procedures, notably to produce arterial capacitance, to regulate arterial blood pressure, to produce aortic counterpulsation and to pump blood. The circular sections of the membrane of the present invention may or may not vary in size, depending on the required function, and are interlinked such that there is a smooth transition between one section and another, irrespective of the size of each section. The present invention further relates to chambers and pumps for extracorporeal circulation and to a pumping system.
(FR) La présente invention concerne des membranes spécialement conçues pour être utilisées dans des chambres pour assistance circulatoire artificielle utilisables principalement dans des procédures cardiovasculaires, notamment pour produire une capacitance artérielle, réguler la pression artérielle, produire une contre-pulsation aortique et pomper le sang. Les sections circulaires de la membrane de la présente invention peuvent varier en taille ou non, selon la fonction à mettre en oeuvre, et sont reliées entre elles de manière que la transition entre une section et l'autre s'opère en douceur, indépendamment de la taille de chaque section. La présente invention concerne également des chambres et des pompes pour circulation extracorporelle, ainsi qu'un système de pompage.
(PT) A presente invenção trata de membranas especialmente desenvolvidas para serem utilizadas em câmaras para assistência circulatória artificial que podem ser empregadas principalmente em procedimentos cardiovasculares, notadamente para produzir capacitância arterial, regular pressão arterial, produzir contrapulsação aórtica e bombear sangue. As seções circulares da membrana da presente invenção podem variar em tamanho ou não, dependendo da função a ser desempenhada, e são interligadas entre si de forma que a transição entre uma seção e a outra seja feita de forma suave, independentemente do tamanho de cada seção. A presente invenção trata ainda de câmaras e bombas para circulação extracorpórea e de um sistema de bombeamento.
