    • A stent comprises at least one stent member woven to form a substantially tubular body that defines a flow path. The tubular body comprises a first region and a second region. In the first region the at least one stent member defines a plurality of first region openings and in the second region at least one first portion of the at least one member and at least one second portion of the at least one member are engaged together to form at least one primary strand. The at least one primary strand defines a plurality of second region openings. The at least one of the plurality of second region openings is in fluid communication with the flow path. The plurality of second region openings provide the second region with a greater porosity than the first region.
    • 支架包括至少一个编织的支架构件,以形成限定流路的基本上管状的主体。 管状体包括第一区域和第二区域。 在第一区域中,至少一个支架构件限定多个第一区域开口,并且在第二区域中,至少一个构件的至少一个第一部分和至少一个构件的至少一个第二部分接合在一起形成 至少一个主链。 至少一个主股限定了多个第二区域开口。 多个第二区域开口中的至少一个与流动路径流体连通。 多个第二区域开口为第二区域提供比第一区域更大的孔隙率。
