    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 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。
