Abstract
stent. a divulgação fornece um stent incluindo: um primeiro suporte anular formando um formato de onda; um segundo suporte anular que é adjacente ao primeiro suporte na direção axial e forma um formato de onda; uma primeira porção de extensão que é formada em uma primeira crista como algumas da pluralidade de cristas que se projetam em direção ao segundo suporte no primeiro suporte e se estendem de ambos os lados em relação a um bissetor da primeira crista em direção ao segundo suporte; uma segunda porção de extensão que é formada em uma segunda crista, a qual está localizada para ser deslocada em uma direção circunferencial em relação à primeira crista dentre a pluralidade de cristas que se projetam em direção ao primeiro lado de suporte no segundo suporte e se estende de ambos os lados em relação ao segundo bissetor da segunda crista em direção ao primeiro suporte; e uma porção de ponte em ponte entre a primeira porção de extensão e a segunda porção de extensão.
