    • A system may include an introducer sheath including a retention member configured to anchor the introducer sheath in a natural body lumen having a wall. The system may also have an elongate member extending along a longitudinal axis through a working channel of the introducer sheath. Additionally, the system may have a manipulating portion coupled to a distal end of the elongate member. The manipulating portion may include at least one selectively actuatable member configured to transition between an undeployed configuration and a deployed configuration. In the undeployed configuration, the at least one actuatable member may extend substantially parallel to the longitudinal axis and in at least one position in the deployed configuration, the at least one actuatable member may extend radially outwardly from the longitudinal axis. In the deployed configuration, the manipulating portion and elongate member may be 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.
    • 系统可以包括引导器护套,其包括保持构件,该保持构件构造成将引导器护套固定在具有壁的天然体腔中。 该系统还可以具有沿着纵向轴线延伸穿过引导器护套的工作通道的细长构件。 另外,系统可以具有联接到细长构件的远端的操纵部分。 操纵部分可以包括至少一个可选择性地启动的构件,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,所述至少一个可致动构件可以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,所述至少一个可致动构件可以从纵向轴线径向向外延伸。 在所展开的构造中,操纵部分和细长构件可构造成朝向引导器护套的工作通道向近端缩回,以使壁的远侧部分朝向壁的近端部分移动。
