    • A system comprising an introducer sheath (30) including a retention member (32) configured to anchor the introducer sheath in a natural body lumen (28) having a wall. The system also has an elongate member (40) extending along a longitudinal axis through a working channel of the introducer sheath and a manipulating portion (42) coupled to a distal end of the elongate member. The manipulating portion include at least one selectively actuatable member (46) configured to transition between an undeployed configuration and a deployed configuration. In the undeployed configuration, the at least one actuatable member extends substantially parallel to the longitudinal axis and in at least one position in the deployed configuration, the at least one actuatable member extends radially outwardly from the longitudinal axis. In the deployed configuration, the manipulating portion and elongate member are configured to be proximally retracted toward the working channel of the introducer sheath so as to move a distal portion of the wall towards a proximal portion of the wall.
    • 一种包括引导器护套(30)的系统,其包括构造成将引导器护套固定在具有壁的天然体腔(28)中的保持构件(32)。 该系统还具有沿着纵向轴线延伸穿过导引器护套的工作通道的细长构件(40)和联接到细长构件的远端的操纵部分(42)。 操纵部分包括至少一个可选择性致动的构件(46),其构造成在未部署构型和展开配置之间过渡。 在未部署的构造中,至少一个可致动构件基本上平行于纵向轴线延伸并且在展开构造中的至少一个位置中延伸,所述至少一个可致动构件从纵向轴线径向向外延伸。 在所展开的构型中,操作部分和细长构件构造成朝向引导器护套的工作通道向近端缩回,以便使壁的远侧部分朝向壁的近侧部分移动。
