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.

Claims

1. A closure system comprising:

a handle member;

a tube set configured to deliver and/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 and an elongate 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 the inner lumen.

2. The closure system of claim 1, the plunger member being longitudinally slidable with respect to the handle member.

3. The closure system of claim 1, a closure element disposed within the tube set in an initial configuration and being configured to move to a deployed configuration once deployed from the tube set.

4. The closure system of claim 1, the plunger member being at least partially disposed within a recess in the handle member.

5. The closure system of claim 1, the inner lumen being movable relative to the tube set and handle member.

6. The closure system of claim 1, the anchor member comprising shape memory or superelastic materials.

7. The closure system of claim 6, the anchor portion further comprising an elongate wire forming the elongate portion and anchor portion.

8. The closure system of claim 1, the expanded configuration of the anchor portion comprising a plurality of projections extending in a direction substantially perpendicular to the longitudinal axis of the elongate portion of the anchor member.

9. The closure system of claim 8, wherein at least one of the projections is shaped similar to a petal or leaf.

10. The closure system of claim 9, wherein the expanded configuration of the anchor portion is substantially similar in shape to a four-leaf clover, figure eight, a ball, or a configuration having more than four leaves.

11. The closure system of claim 1, wherein the elongate portion of the anchor member is coupled to the plunger member.

12. The closure system of claim 11, wherein the plunger member is configured to slide in a distal direction relative to the handle member to deploy the anchor portion of the anchor member.

13. The closure system of claim 12, wherein the handle member is configured to move in a distal direction relative to the plunger member to advance the distal end of the tube set to proximity with the anchor portion of the anchor member.

14. The closure system of claim 1, further comprising the handle member and/or tube set being configured to deploy the closure element from the distal end of the tube set.

15. The closure system of claim 1, the closure element comprising a clip or staple.

16. The closure system of claim 1, the handle member further comprising one or more indentations or flanges configured to facilitate gripping or manipulating the handle member.

17. The closure system of claim 1, wherein the tube set comprises a garage tube, a pusher tube, and a carrier tube.

18. A method of closing a body lumen opening 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 and/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 and an elongate 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 the inner lumen.

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.

19. The method of claim 18, further comprising advancing the plunger member to deploy the anchor portion of the anchor member and retracting the plunger member to retract the anchor portion of the anchor member.

20. An anchor member comprising:

an elongate portion having a distal end and proximal end;

an anchor portion coupled to the distal end of the elongate portion, the anchor portion being configured to move elastically between an initial configuration and an expanded configuration, the expanded configuration comprising a plurality of projections.

21. The anchor member of claim 20, wherein the plurality of projections extend in a direction substantially perpendicular to the longitudinal axis of the elongate portion.

22. The anchor member of claim 20, the plurality of projections comprising at least 2 projections.

23. The anchor member of claim 20, further comprising the anchor member comprising a shape memory or superelastic wire being set in the expanded configuration.

24. The anchor member of claim 20, the elongate portion comprising a first elongate member and a second elongate member.

25. The anchor member of claim 24, wherein the anchor portion is configured to provide more resistance to movement from an expanded configuration to a contracted configuration when tension is applied to both the first elongate member and the second elongate member than when tension is only applied to one of the first elongate member and second elongate member.

26. The anchor member of claim 20, wherein the expanded configuration is substantially similar in shape to a four-leaf clover, figure eight, a ball, or a configuration having more than four leaves.
