1. A closure system comprising:
- a handle member;
a tube set configured to deliver or deploy a closure element, the tube set having a distal end and a proximal end, the proximal end of the tube set being coupled to the handle member;
an inner lumen disposed at least partially within the tube set;
a plunger member movably coupled to the handle member; and
an anchor member at least partially disposed within the inner lumen, the anchor member comprising an anchor portion, a first elongate portion, and a second elongate portion, the anchor portion being disposed in the inner lumen in an initial configuration and configured to move to an expanded configuration in a transverse plane to said elongate portion once deployed from the inner lumen without additional external force, the expanded configuration including a first portion and a second portion, the second portion being an inverted mirror image of the first portion about an intersection between the first portion and the second portion, the first elongate portion, the second elongate portion, the first portion, and the inverted second portion are continuously connected the anchor member configured to locate the closure system within a body lumen, the anchor member being configured to be retracted through the closure element.

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.

18. A closure system comprising:
-
a handle member; a tube set including one or more tubular members configured to contain, deliver or deploy a closure element, the tube set having a distal end and a proximal end, the proximal end of the tube set being coupled to the handle member, wherein the closure element is disposed within the tube set in an open configuration; an inner lumen disposed at least partially within the tube set; a plunger member movably coupled to the handle member; and an anchor member at least partially disposed within the inner lumen, the anchor member comprising a first elongated portion, a second elongated portion, and an anchor portion with at least two looped portions, the first elongated portion, the second elongated portion, and the anchor member, with the at least two looped portions, being continuously connected from the first elongated portion to the second elongated portion, the anchor portion being disposed in the inner lumen in an initial configuration and configured to move to an expanded configuration once deployed from within the inner lumen without additional external force, wherein distal movement of the plunger member deploys the anchor member to the expanded configuration and proximal movement of the plunger member retracts the anchor member back to the initial configuration, the expanded configuration including a first portion and a second portion, the second portion being an inverted mirror image of the first portion about an intersection between the first portion and the second portion the anchor member configured to locate the closure system within a body lumen, the anchor member being configured to be retracted through the closure element. - View Dependent Claims (19, 20, 21, 22)

23. A method of closing a body lumen opening having a lumen wall comprising:
-
advancing a closure system at least partially into a body lumen opening, the closure system comprising; a handle member; a tube set configured to deliver or deploy a closure element, the tube set having a distal end and a proximal end, the proximal end of the tube set being coupled to the handle member; an inner lumen disposed at least partially within the tube set; a plunger member movably coupled to the handle member; and an anchor member at least partially disposed within the inner lumen, the anchor member comprising an anchor portion having at least two looped portions and a pair of elongate portions, the anchor portion, with the at least two looped portions, and the pair of elongate portions being continuously connected together, the anchor portion being disposed in the inner lumen in an initial configuration and configured to move to an expanded configuration in a transverse plane to said first elongate portion and said second elongate portion once deployed from the inner lumen without external force, the expanded configuration including a first portion and a second portion, the second portion being an inverted mirror image of the first portion about an intersection between the first portion and the second portion, the first elongate portion, the second elongate portion, the first portion, and the inverted second portion are continuously connected the anchor member configured to locate the closure system within the body lumen, the anchor member being configured to be retracted through the closure element; deploying the anchor portion of the anchor member within the body lumen; positioning the anchor portion of the anchor member against a distal surface of the lumen wall proximate the body lumen opening; advancing the tube set in a distal direction to position the distal end of the tube set against a proximal surface of the lumen wall proximate the body lumen opening; and deploying a closure element into the lumen wall proximate the body lumen opening to close the body lumen opening. - View Dependent Claims (24)
