Abstract: The present disclosure relates generally to methods and devices for closing and/or sealing an opening in a vessel wall and/or an adjacent tissue tract. In some cases, the device includes a sheath having a distal end that can expand radially as needed. In some cases, the distal portion of the sheath is weakened so that it may tear in a predetermined manner. In some cases, the distal portion of the sheath is weakened so that it may deform plastically in a predetermined manner. In some cases, the distal portion of the sheath or the entire sheath may be folded so that it unfolds in a predetermined manner. In general, each of these sheaths may have a relatively small introduction profile, may have a distal portion that can expand to a larger diameter than the introduction profile during use, and can be collapsed again to a smaller profile for removal.

Abstract: A stent assembly includes a stent, a covering on at least a portion of the stent, and a string encircling at least a portion of the covering. The string is releasably engaged to the covering or stent or both the covering and the stent. The string can be adhered to the stent, or the stent assembly, to the covering of the stent assembly, or both the covering and the stent. The string can be wrapped around the stent or covering in an interwoven loop or knit pattern. The covering can be made to overlap a perforation in a body lumen such as an artery or blood vessel and prevent bleeding.

Abstract translation: 支架组件包括支架，支架的至少一部分上的覆盖物和围绕至少一部分覆盖物的绳索。 绳子可释放地接合到覆盖物或支架或覆盖物和支架两者。 绳可以粘附到支架或支架组件到支架组件的覆盖物或覆盖物和支架两者上。 绳子可以缠绕在支架上或以交织的环圈或编织图案覆盖。 可以使覆盖物与诸如动脉或血管的体腔中的穿孔重叠，并防止出血。

Abstract translation: 本公开一般涉及关闭和/或密封血管壁和/或相邻组织道中的开口的方法和装置。 在一些情况下，该装置包括具有能够根据需要径向膨胀的远端的护套。 在一些情况下，护套的远端部分被削弱，使得其可以以预定的方式撕裂。 在一些情况下，护套的远端部分被削弱，使得其可以以预定的方式塑性变形。 在一些情况下，护套的远侧部分或整个护套可以被折叠，使得它以预定的方式展开。 通常，这些护套中的每一个可以具有相对较小的引入轮廓，可以具有在使用期间可以扩展到比引入轮廓更大的直径的远侧部分，并且可以再次折叠成更小的轮廓以便移除。
