    • A repositionable closure device for occluding a body opening is provided. The closure device includes distal and proximal occluding bodies having expandable distal and proximal umbrella frames. Each umbrella frame includes a plurality of struts connected to a biocompatible sheet material. The distal and proximal umbrella frames expand to expanded configurations on opposite sides of the body opening. The struts of the distal umbrella frame terminate with an eyelet. The distal occluding body is connected to a distal end of a center rod and the proximal umbrella frame is slidable along the center rod via a center ring. At least one drawstring is threaded through the eyelets and the center ring, connecting the distal and proximal occluding bodies. The drawstring extends proximally from the center ring. Manipulation of the drawstring and the center rod is configured to collapse the closure device for at least partial retrieval during repositioning.
    • 提供了一种用于封闭体开口的可重新定位的闭合装置。 闭合装置包括具有可扩展的远侧和近侧伞形框架的远端和近端闭塞体。 每个伞形框架包括连接到生物相容片材的多个支柱。 远端和近侧伞架在主体开口的相对侧上膨胀成扩展构型。 远侧伞架的支柱用孔眼终止。 远侧闭塞体连接到中心杆的远端,并且近侧伞形框架可以经由中心环沿着中心杆滑动。 至少一条束带穿过孔眼和中心环,连接远端和近端闭塞体。 束带从中心环向近端延伸。 束带和中心杆的操纵被配置为在重新定位期间使封闭装置折叠至少部分恢复。
