Abstract

trata-se de implantes embólicos macios que exibem formatos secundários. alguns dos implantes embólicos exibem maciez progressivamente crescente desde a extremidade distal até a extremidade proximal da bobina. os implantes embólicos têm uma bobina primária, uma segunda bobina opcional, um fio de formato e uma fibra resistente a estiramento disposta no lúmen da bobina primária. um fio de sustentação distal opcional também é revelado. os implantes embólicos incluem um conjunto de restrição proximal configurado para ser retido de modo liberável por um dispositivo de entrega. as arruelas de orifício elípticas estão dispostos em proximidade de cada extremidade de alguns dos implantes, através das quais o fio de formato e a fibra resistente a estiramento são rosqueados. os implantes embólicos têm uma configuração primária linear para entrega através de uma ferramenta de implante, e uma configuração secundária após o posicionamento a partir da ferramenta de implante. o formato secundário pode ser em formato de j, helicoidal, esférico, complexo ou uma combinação de formatos.
