Abstract

A device for closing an aperture in a vessel wall comprising a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture and a first spherical retainer positionable external of the vessel. The covering member has a dimension to prevent egress of fluid through the aperture.

Claims

1-14. -14. (canceled)

15. A method of closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall, the method comprising:

inserting a covering member inside the vessel and moving the covering member in a first direction to position the covering member against the internal opening of the aperture, the covering member having a dimension to prevent egress of fluid through the aperture; and

inserting a first spherical retainer external of the vessel; and

advancing the first retainer toward the covering member in a second different direction for placement external of the vessel to retain the covering member.

16. The method of claim 15, wherein the step of advancing the first retainer comprises the step of moving a suture, the first retainer fixedly attached to the suture.

17. The method of claim 16, further comprising the step of inserting a second spherical retainer external of the vessel.

18. The method of claim 17, further comprising the step of advancing the second retainer in the second direction toward the covering member.

19. The method of claim 18, wherein the second retainer is advanced by suture movement.

20. The method of claim 19, wherein the first and second retainers are placed in substantially side by side relationship and left in the body to resorb over a period of time.

21. A method of closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall, the method comprising:

providing a closure device having a covering member, a first retainer and a second retainer;

inserting the covering member inside the vessel against the internal opening of the aperture, the covering member having a dimension to prevent egress of fluid through the aperture;

advancing the first retainer toward the covering member for placement proximal of the covering member and external of the vessel; and

advancing the second retainer toward the covering member for placement proximal of the covering member and external of the vessel.

22. The method of claim 21, wherein the step of advancing the first retainer toward the covering member comprises the step of pulling a first suture proximally.

23. The method of claim 22, wherein the step of advancing the second retainer toward the covering member comprises the step of pulling a second suture proximally.

24. The method of claim 21, wherein the step of advancing the second retainer toward the covering member comprises the step of pulling a second suture proximally.

25. The method of claim 22, wherein the first suture is coupled to the covering member and the first suture positions the covering member against an internal wall of the vessel.

26. The method of claim 23, wherein the second suture is coupled to the covering member and the second suture positions the covering member against an internal wall of the vessel.

27. The method of claim 22, wherein the covering member has first and second openings to receive the first suture such that proximal movement of the first suture moves the first suture within the first and second openings.

28. The method of claim 23, wherein the steps of advancing the first and second retainers places the first and second retainers in position in side by side relationship external of the vessel.

29. The method of claim 21, wherein delivery of the covering member enables the covering member to pivot from a longitudinal delivery position to a transverse position within the vessel.

30. The method of claim 21, wherein the first and second retainers are held in a stacked relationship for delivery.

31. The method of claim 21, wherein the second retainer is within a delivery tube when the first retainer is initially advanced from the tube.

32. The method of claim 21, further comprising the step of leaving the closure device in the body to resorb over a period of time.

33. The method of claim 21, further comprising the step of inserting a delivery instrument into the vessel.

34. The method of claim 21, wherein the covering member is moved into contact with an internal wall of the vessel prior to the step of advancing the first retainer.
