Stent delivery systems, locking members for preventing unwanted actuation of a actuation member on a stent delivery system, and methods for making and using the same are disclosed. An example stent delivery system may include an inner member. A deployment sheath may be disposed about the inner member. A stent may be disposed between the inner member and the deployment sheath. A handle may be coupled to the inner member and to the deployment sheath. The handle may include an actuation member. The actuation member may be configured to shift the longitudinal position of the deployment sheath relative to the inner member. A locking member may be disposed on the actuation member. The locking member may be configured to prevent unwanted actuation of the actuation member.

Stent delivery systems and locking members for use with stent delivery systems

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.

In some embodiments, a stent comprises a side branch structure defining an inner side branch cell. The inner side branch cell has a shape that is different from any other cell of the stent. The stent further comprises first and second support members, which are positioned on opposite sides of the side branch structure. The first and second support members each have a strut width that is greater than the width of a strut included in the side branch structure. The stent further comprises first and second connecting members, which are positioned on opposite ends of the side branch structure. Each connecting member is connected at one end to the first support member and is connected at the other end to the second support member. Each connecting member comprises a serpentine structure having a plurality of straight struts and turns. One or both of the connecting members includes at least one straight strut that has a length that is at least ten times its width. In some embodiments, each connecting member comprises at least four struts that have a length that is at least then times their width.
