Abstract[English]
A mechanical thrombectomy device, and methods of manufacturing and using the mechanical thrombectomy device, are described. The mechanical thrombectomy device includes several clot arrestors independently mounted on a support wire. The clot arrestors have expandable frames that are eccentrically supported on the support wire. The independently and eccentrically mounted clot arrestors are arranged to allow a clot to pass into, and be captured by, one of the expandable frames. Furthermore, the independently and eccentrically mounted clot arrestors deform independently of one another such that retraction of the mechanical thrombectomy device through tortuous vasculature can stretch one clot arrestor without stretching another one of the clot arrestors to allow the clot to be retained by the unstretched clot arrestors. Other embodiments are also described and claimed.[French]
L'invention concerne un dispositif de thrombectomie mécanique et des procédés de fabrication et d'utilisation du dispositif de thrombectomie mécanique. Le dispositif de thrombectomie mécanique comprend plusieurs dispositifs d'arrêt de caillot montés indépendamment sur un fil de soutien. Les dispositifs d'arrêt de caillot ont des cadres extensibles qui sont soutenus excentriques sur le fil de soutien. Les dispositifs d'arrêt de caillot montés indépendants et excentriques sont agencés pour permettre à un caillot de passer dans l'un des cadres extensibles et d'être capturé par ce dernier. En outre, les dispositifs d'arrêt de caillot montés indépendants et excentriques se déforment de manière indépendante l'un de l'autre de telle sorte que la rétraction du dispositif de thrombectomie mécanique à travers le système vasculaire tortueux peut étirer un dispositif d'arrêt de caillot sans étirer d'autres dispositifs d'arrêt de caillot pour permettre au caillot d'être retenu par les dispositifs d'arrêt de caillot non étirés. D'autres modes de réalisation sont également décrits et revendiqués.
