Title (EN) INTRAVASCULAR BLOOD PUMP WITH BALLOON
(FR) POMPE SANGUINE INTRAVASCULAIRE À BALLONNET
Abstract:
(EN) An intravascular blood pump (1) comprises a ring seal (10) that is configured to assume a collapsed configuration and an expanded configuration and configured to contact and seal against an inner wall of the patient' s blood vessel when inserted therein in the expanded configuration. A support member (12;13) is disposed inside the ring seal ( 10) in order to support the ring seal (10) from the inside, wherein the support member (12; 13) is configured to collapse at least partially when a predetermined pressure difference between a proximal area and a distal area of the blood vessel acting on the ring seal (10) is exceeded.
(FR) La présente invention concerne une pompe sanguine intravasculaire (1) comprenant un joint d'étanchéité annulaire (10) qui est configuré pour prendre une configuration repliée et une configuration déployée et configuré pour entrer en contact avec une paroi interne du vaisseau sanguin du patient et sceller celle-ci lorsqu'il est inséré dans celle-ci dans la configuration déployée. Un élément de support (12; 13) est disposé à l'intérieur du joint d'étanchéité annulaire (10) afin de supporter le joint d'étanchéité annulaire (10) à partir de l'intérieur, l'élément de support (12; 13) est configuré pour se replier au moins partiellement lorsqu'une différence de pression prédéterminée entre une zone proximale et une zone distale du vaisseau sanguin agissant sur le joint d'étanchéité annulaire (10) est dépassée.
