Abstract
Esta divulgación describe dispositivos intravasculares micro fabricados que están configurados para una alta resistencia axial, manteniendo al mismo tiempo una flexibilidad de flexión efectiva. Un miembro tubular incluye una serie de anillos que se extienden circunferencialmente conectados entre sí por una serie de vigas que se extienden axialmente. Los cortes transversales separan y definen los anillos. Una serie de cortes axiales están alineados con las vigas y se extienden desde las vigas parcialmente dentro de los anillos contiguos, de modo que la longitud de la viga está anidada parcialmente dentro de la longitud axial de los anillos contiguos. De este modo se aumenta la longitud funcional de los largueros para proporcionar flexibilidad a la flexión, al tiempo que se mantiene una estructura anular suficiente para proporcionar una rigidez axial efectiva
