Abstract

resumo “materiais porosos com uma microestrutura fibrilares e um revestimento fraturável” os artigos feitos de um material poroso que tem uma microestrutura fibrilar de fibrilas curvadas e fornecidas com um revestimento quebradiço em que o tamanho físico do artigo pode ser alterado por meio da aplicação de força ao artigo em uma direção substancialmente paralela a uma direção de orientação das fibrilas. a aplicação de uma força de tração para um tal artigo, em uma direção substancialmente paralela à orientação das fibrilas curvadas resultados em fratura do material quebradiço e estiramento das fibras curvadas. os métodos para fazer tais artigos são também descritos. os artigos podem incluir artigos implantáveis, tais como enxertos vasculares e endopróteses; tais dispositivos podem, por exemplo, ser aumentado pela força de diâmetro ou comprimento em que os resultados de força na fratura do revestimento. um tal material de revestimento é de politetrafluoretileno expandido poroso fornecido com um revestimento de etileno - propileno fluorado.
