Abstract

"MECANISMO PARA O DESENVOLVIMENTO DE IMPLANTE ENDOVASCULARES". A invenção refere-se a um mecanismo para o desenvolvimento de um dispositivo endovascular filamentoso que inclui um tubo de desenvolvimento alongado, flexível, oco, tendo uma extremidade próxima aberta e um elemento de acoplamento preso à extremidade próxima do dispositivo endovascular. O tubo de desenvolvimento inclui uma seção distal que termina em uma extremidade distal aberta, com um lúmen definido entre as extremidades próxima e distal. Uma luva de retenção é fixada em torno da seção distal e inclui uma extensão distal que se estende por uma curta distância além da extremidade distal do tubo de desenvolvimento. O dispositivo endovascular é preso à extremidade distal do tubo de desenvolvimento durante o processo de fabricação através da fixação da luva de retenção em torno do elemento de acoplamento, de modo que o elemento de acoplamento fica mantido liberavelmente dentro da extensão distal do tubo de desenvolvimento. Em uso, o tubo de desenvolvimento, com o implante preso a sua extremidade distal, é passado através de um microcateter para um alvo vascular alvo até que o dispositivo endovascular fique desdobrado dentro do alvo. Para separar o dispositivo endovascular do tubo de desenvolvimento, um líquido biocompatível é injetado através do lúmen do tubo de desenvolvimento de modo a aplicar preso ao lado a montante do elemento de acoplamento, que é, assim, empurrado para fora da luva de retenção pela pressão de fluido, assim, separando o dispositivo endovascular do tubo de desenvolvimento. O elemento de acoplamento pode ser um "tampão" sólido de material polimérico ou metal, ou pode ser formado de um polímero hidrofílico que amolece e se torna um pouco escorregadio, quando contatado pelo líquido injetado. Com este último tipo de material, a hidratação do material hidrofílico resulta em mudanças físicas que reduzem a adesão entre o elemento de acoplamento e a luva. Alternativamente, o elemento de acoplamento pode ser feito principalmente de um material não hidrofílico, com um revestimento hidrofílico.
