Abstract

DISPOSITIVOS E MÉTODOS PARA TRATAR VASOS SANGUÍNEOS BIFURCADOS. São descritos no presente documento dispositivos médicos e métodos para colocar um stent bifurcado em um vaso sanguíneo bifurcado. Além disso, são descritos no presente documento métodos para tratar doença oclusiva aorto-ilíaca. O stent bifurcado pode ser montado sobre um cateter que compreende pelo menos dois balões montando-se um primeiro stent de ramificação do stent bifurcado sobre um primeiro balão e um segundo stent de ramificação do stent bifurcado sobre um segundo balão e um corpo principal do stent bifurcado sobre o primeiro balão e o segundo balão.
