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.
