Abstract

A closure device configured for closing an opening in a body lumen. The closure device may include a delivery sheath, a cleat, and one or more anchors. The cleat may be disposed within and move longitudinally with respect to the delivery sheath. The one or more anchors may be configured to engage tissue surrounding the body lumen opening and selectively couple to the cleat to obstruct and/or close the body lumen opening.

Claims

1. A closure device for closing an opening in a body lumen comprising:

a delivery sheath;

a cleat configured to be disposed within and move longitudinally with respect to the delivery sheath; and

one or more anchors configured to engage tissue surrounding the body lumen opening and couple with the cleat.

5. The closure device of claim 1, further comprising one or more elongate members coupled at a distal end to the one or more anchors and configured to pass through and be slidable relative to the cleat.

6. The closure device of claim 5, wherein the one or more elongate members comprise superelastic wires.

7. The closure device of claim 1, further comprising a mandrel being configured to selectively couple to the cleat.

8. The closure device of claim 7, wherein the mandrel comprises a hollow metal shank.

9. The closure device of claim 1, wherein the cleat comprises bioabsorbable plastic.

10. The closure device of claim 1, wherein the one or more anchors comprise bioabsorbable plastic.

11. The closure device of claim 1, wherein each anchor comprises a hook portion configured to engage tissue and a collar portion configured to couple with the cleat.

12. The closure device of claim 1, wherein the recesses include flared distal openings.

2. The closure device of claim 2, further comprising the cleat having one or more recesses configured to receive the one or more anchors.

3. The closure device of claim 3, further comprising the one or more recesses and one or more anchors being configured to lock together.

4. The closure device of claim 4, further comprising the one or more anchors being configured to lock into the one or more recesses with a snap-fit configuration.

13. A method of closing an opening in a body lumen comprising:

advancing a closure device at least partially into the body lumen opening, the closure device comprising;

a delivery sheath;

a cleat disposed within the delivery sheath; and

one or more anchors disposed within the delivery sheath distal of the cleat;

deploying the one or more anchors from a distal end of the delivery sheath; and

engaging a distal surface of the body lumen with the one or more anchors.

14. The method of claim 13, further comprising advancing the cleat in a distal direction over one or more elongate members coupled at a distal end to the one or more anchors to pull the anchors and engaged tissue together.

15. The method of claim 14, wherein advancing the cleat in a distal direction comprises advancing a mandrel coupled to the cleat in a distal direction relative to the one or more elongate members and one or more anchors.

16. The method of claim 15, further comprising locking the anchors into correspondingly-shaped recesses within the cleat.

17. The method of claim 16, further comprising uncoupling the mandrel from the cleat.

18. The method of claim 17, further comprising trimming the elongate members proximal of the cleat.

19. The method of claim 18, further comprising retracting the delivery sheath, one or more elongate members, and mandrel away from the body lumen.

20. The method of claim 19, wherein the one or more elongate members comprise super elastic wires, the cleat comprises bioabsorbable plastic, and the one or more anchors comprise bioabsorbable plastic.
