Abstract

resumo "aparelho de restrição de fluxo sanguíneo e processo para remoção de êmbolo em vasculatura humana" um sistema de dispositivo de trombectomia mecânica é descrito, que é pro-duzido de uma peça única de material biocompatível, incluindo uma parte / configu-ração de bloqueio de fluxo proximal e/ou uma configuração de bloqueio de fluxo na parte de corpo do dispositivo, um fio de guia como a parte de transferência e uma parte de tratamento expansível. a construção do dispositivo de uma peça única pro-picia uma transição sem emenda da parte de transferência para a parte de tratamen-to, desse modo, eliminando quaisquer juntas ou aglutinação das duas partes entre si, como peças separadas. isso aperfeiçoa a resistência mecânica do sistema como um todo e reduz bastante a possibilidade das duas partes de inadvertidamente fica-rem soltas entre si. igualmente, a parte de tratamento distal é cortada de uma peça de material de mesmo tamanho que a parte de transferência proximal, permitindo que o dispositivo seja compactado a um perfil de tamanho similar, conferindo a ele vantagens de transferência, incluindo uma força de transferência menor necessária, e requerendo sistemas de acesso menores, e a superfície da parte de tratamento pode ser alterada para aumentar a afinidade do êmbolo por revestimento com uma substância ou mudança da textura por meio mecânico ou químico.
