Abstract

dispositivo intraluminal com flexibilidade e durabilidade aprimorada. o stent (150) da presente invenção é um membro tubular tendo extremidades anterior e posterior abertas e um eixo longitudinal que se estende entre elas. o membro tubular tem um primeiro diâmetro menor para inserção em um paciente e navegação entre os vasos, e um segundo diâmetro maior para implantação na área alvo de um vaso. o membro tubular é feito de uma pluralidade de arcos (152(a), 152(b), 152(c), 152(d) que se estendem entre as extremidades anterior e posterior os arcos incluem uma pluralidade de braços longitudinais (160) e uma pluralidade de laços (162) que conectam adjacentemente os braços. o stent inclui ainda uma pluralidade de pontes (170) que têm laço para ligar as conexões que conectam arcos adjacentes um ao outro. a razão entre o número total de laços alinhados circunferencialmente e o número de laços originados por uma ponte particular é um número inteiro.
