Abstract
"CATETER DE EMBOLECTOMIA E SISTEMA COMPREENDENDO UM CATETER". Cateteres de embolectomia (10, 10<39>, 10<39><39>, 10<39><39><39>, 10<39><39><39><39>), microcateteres de troca rápida, sistemas e processos para remover coágulos sanguíneos ou outro material obstrutivo (p.ex. trombos, tromboêmbolos, fragmentos embólicos de placa ateroesclerótica, objetos estranhos, etc. de vasos sanguíneos, A presente invenção é particularmente útil para remoção percutânea de tromboêmbolos ou outra matéria obstrutiva de pequenos vasos sanguíneos do cérebro, durante um ataque em evolução ou período de isquemia cerebral. Em algumas concretizações, os cateteres de embolectomia (10, 10<39><9>, 10<39><39><39>, 10<39><39><39><39>) da presente invenção são avançáveis com ou através de um fio guia (GW) que foi pré-inserido através de ou em torno do coágulo. Também em algumas concretizações, os cateteres de embolectomia inclui dispositivos removedores de coágulo que são expansíveis após o cateter ter sido avançado pelo menos parcialmente através do coágulo. O dispositivo removedor de coágulos pode incluir um ninho de fio expansível (14) que é projetado para prevenir que um coágulo de sangue passe através do mesmo. O cateter administrador pode incluir tubos interno e externo telescópicos, com o dispositivo removedor de coágulo sendo radialmente reprimido pelo tubo externo. A retração do tubo externo remover a ação repressora sobre o dispositivo removedor de coágulo e permite que se expanda para sua configuração expandida. Um fio guia de infusão é particularmente útil em conjunção com o cateter de embolectomia, e permite a infusão de medicamentos ou fluidos de visualização distal para o coágulo.
