Abstract

stent vascular. trata-se de um stent de vaso sanguíneo, que compreende um corpo de stent. o corpo de stent é uma estrutura tubular reticulada tecida por fios de metal, em que o corpo de stent compreende um primeiro segmento de stent e um segundo segmento de stent que são conectados na direção axial, e a densidade de malha do primeiro segmento de stent é diferente daquele de um segmento de stent. o stent de vaso sanguíneo fornecido na presente invenção pode aprimorar o efeito do tratamento para envolver a estenose de veia cava inferior e veia iliofemoral por meio de seções descobertas, pode aprimorar a força de suporte e o desempenho anticompressão para uma parte de compressão por meio de uma estrutura de tela densa com densidade de malha maior, pode aumentar a flexibilidade e o desempenho de adesão de parede para uma parte flexível por meio de uma estrutura de malha esparsa com densidade de malha menor, pode adaptar às formas dos vasos sanguíneos para diferentes formas anatômicas de vasos sanguíneos, por meio de uma estrutura de diâmetro variável, e é adequado para vários diâmetros de vasos sanguíneos.
