Abstract
dispositivo de embolizaçãoe bobina de mola do mesmo. a presente invenção refere-se a um dispositivo de embolização e a uma bobina do mesmo (10, 20, 30). a bobina (10, 20, 30) é formada unindo entre si pelo menos quatro elementos estruturais em planos diferentes, que incluem pelo menos dois elementos em forma de c (12) e pelo menos um elemento em forma de o (13) ou em forma de ¿ (11). pelo menos dois elementos em forma de c (12) são dispostas em dois planos adjacentes e são sequencialmente unidos entre si para formar uma estrutura em forma de s. o dispositivo de embolização preferivelmente inclui uma pluralidade de bobinas (10, 20, 30) que apresenta as bobinas unidas entre si lado a lado e extremidade a extremidade, em que, em quaisquer duas bobinas adjacentes (10, 20, 30), uma é girada em torno de um eixo do dispositivo de embolização em relação à outra. o elemento em forma de ¿ é estruturalmente estável, permitindo que a bobina (10, 20, 30) mantenha uma boa estabilidade estrutural. ao mesmo tempo, a estrutura tridimensional em forma de s apresenta uma boa deflexibilidade, o que confere uma alta conformidade à bobina (10, 20, 30). com esta construção, a bobina (10, 20, 30) pode satisfazer os requisitos tanto de uma formação de cesta estável quanto uma compactação compatível e pode se adaptar a vários aneurismas de diferentes formas e tamanhos com um efeito de compactação denso.
