Abstract

The present disclosure includes vessel closure devices, systems, and methods. A closure system configured to close a body lumen opening may include a handle member. A tube set configured to deliver and/or deploy a closure element may be coupled to the handle member. The closure system may also include an inner lumen with an anchor member at least partially disposed in the inner lumen. A plunger member may be movably coupled to the handle member.

         27 . An anchor member configured to locate and/or anchor tissue surrounding a body lumen opening comprising:
 an elongate portion configured to be manipulated by a user and slidably received within a longitudinal lumen of a tubular member, the elongate portion having at least a first elongate member; and   an anchor portion having one or more contracted configurations when positioned in the longitudinal lumen of the tubular member, the one or more contracted configurations capable of passing through a body lumen opening, and the anchor portion having one or more expanded configurations capable of anchoring tissue surrounding a body lumen opening, wherein the anchor portion is movable between the one or more contracted configurations and the one or more expanded configurations by moving the first elongate member longitudinally relative to the tubular member.   
     
     
         28 . The anchor member of  claim 27 , wherein the anchor member includes a shape-memory material. 
     
     
         29 . The anchor member of  claim 28 , wherein the anchor member includes a shape memory wire forming both the elongate portion and the anchor portion. 
     
     
         30 . The anchor member of  claim 27 , wherein the one or more contracted configurations are substantially perpendicular to the one or more expanded configurations. 
     
     
         31 . The anchor member of  claim 27 , wherein the one or more expanded configurations include at least one rounded projection. 
     
     
         32 . The anchor member of  claim 31 , wherein the at least one rounded projection is connected to a straight portion of the anchor portion. 
     
     
         33 . The anchor member of  claim 32 , wherein the at least one rounded projection turns at least 180 degrees before the straight portion. 
     
     
         34 . The anchor member of  claim 27 , wherein the anchor portion has a first end and a second end, the first end being connected to the elongate portion and the anchor portion terminating at the second end. 
     
     
         35 . The anchor member of  claim 27 , wherein the elongate member has a tubular configuration. 
     
     
         36 . The anchor member of  claim 35 , wherein the anchor member has a first end and a second end, the first end and second end being connected to the elongate portion. 
     
     
         37 . An anchor member configured to locate and/or anchor tissue surrounding a body lumen opening comprising:
 an elongate portion configured to be manipulated by a user and slidably received within a longitudinal lumen of a tubular member, the elongate portion having at least a first elongate member, the elongate portion having a longitudinal axis; and   an anchor portion having a contracted configuration capable of passing through a body lumen opening and having an expanded configuration capable of anchoring tissue surrounding a body lumen opening, wherein the expanded configuration has a plurality of projections including at least a first projection and a second projection extending radially outward relative to the longitudinal axis, the first projection having a first radially outwardmost point and the second projection having a second radially outwardmost point, the first radially outwardmost point and second radially outwardmost point radially opposing one another.   
     
     
         38 . The anchor member of  claim 37 , wherein the first radially outwardmost point has a first radius relative to the longitudinal axis and the second radially outwardmost point has a second radius relative the longitudinal axis, the first radius and second radius being the same. 
     
     
         39 . The anchor member of  claim 37 , wherein the plurality of projections are oriented at equal rotational intervals about the longitudinal axis. 
     
     
         40 . The anchor member of  claim 37 , wherein at least a portion of a projection of the plurality of projections longitudinally overlaps a portion of another projection of the plurality of projections in the expanded configuration. 
     
     
         41 . The anchor member of  claim 37 , wherein at least a portion of a projection of the plurality of projections longitudinally overlaps a portion of another projection of the plurality of projections in the contracted configuration. 
     
     
         42 . A method of closing an opening in a body lumen, the method comprising:
 positioning at least part of closure system through an opening in a bodily lumen;   deploying an anchor member of the closure system in a bodily lumen, the anchor member having a longitudinal axis, an elongate portion, and an anchor portion, the elongate portion being substantially parallel to the longitudinal axis,   applying force in a distal direction to an elongate member of the elongate portion to move the anchor portion from a contracted configuration to an expanded configuration;   applying force in a proximal direction to move the anchor portion proximally and against the bodily lumen; and   retracting the elongate member of the elongate portion and maintaining at least part of the anchor member stationary to collapse the anchor member from the expanded configuration to the contracted configuration.   
     
     
         43 . The method of  claim 42 , wherein applying force in a distal direction to the elongate member includes maintaining at least part of the anchor member stationary longitudinally and moving at least part of the anchor member radially relative to the longitudinal axis. 
     
     
         44 . The method of  claim 43 , wherein moving at least part of the anchor member radially relative to the longitudinal axis includes expanding a plurality of rounded projections. 
     
     
         45 . The method of  claim 44 , wherein applying force in a proximal direction to move the anchor portion proximally and against the bodily lumen comprises contacting the bodily lumen with the plurality of rounded projections. 
     
     
         46 . The method of  claim 44 , wherein the plurality of rounded projections extend perpendicularly to the longitudinal axis.
