    • A luminal occlusion device comprises a tension member, an elongate shaft, and a flat film having an axial receptacle which is received over a distal portion of the tension member. The flat film has proximal and distal ends which are attached to the distal ends of the tension member and the elongate shaft, respectively. Thus, distal advancement of the tension member relative to the shaft will cause the flat film to assume a low profile configuration, while proximal retraction of the tension member relative to the elongate shaft will cause the flat film to assume a foreshortened, compacted configuration. The film usually includes one or more radioopaque markers which help shape the compacted film.
    • 管腔闭塞装置包括张力构件,细长轴和具有轴承座的扁平膜,所述轴向容纳件容纳在所述张力构件的远侧部分上。 平膜具有近端和远端,它们分别附接到张紧构件和细长轴的远端。 因此,张力构件相对于轴的远侧前进将导致平膜呈现低轮廓构型,而张紧构件相对于细长轴的近端缩回将导致平膜呈现缩短的压实构型。 该膜通常包括一个或多个不透射线的标记,其有助于形成压实膜。
