Abstract
In one illustrative example, a device for sealing an opening in a vessel wall and/or tissue tract may include an anchor, a filament, a plug, and a knot. The anchor may be configured to be disposed adjacent to an interior surface of the vessel wall adjacent the opening in the vessel wall. The filament may have a distal end coupled to the anchor and may be configured to extend proximally through the vessel opening and/or tissue tract. The plug may be disposed about at least a portion of the filament member. The knot may be disposed about the filament proximal of the plug and may be configured to move over the filament and secure the plug relative to the anchor. The knot may be independent of the filament member.
