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 having a dimension to prevent egress of fluid through the aperture and having a first opening. A first retainer is positionable external of the vessel. A flexible connecting member operatively connects the covering member and the first retainer, wherein the first opening of the covering member is configured to restrict movement of the connecting member.

First claim

What is claimed is:

1. A hole closure device for 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 hole closure device comprising:
a first member having a first width in a delivery position and in a placement position;
a second member; and
a flexible connecting member having a first end and a second end, the flexible connecting member operatively connecting the first member and the second member, the first member secured to the flexible connecting member and positioned on the second end of the flexible connecting member, wherein pulling the first end of the flexible connecting member advances the first member toward the second member, wherein movement of the flexible connecting member in a proximal direction advances the first member toward the second member in a distal direction for placement of the first member in the placement position, the flexible connecting member being restricted from movement and retained in a fixed position by the hole closure device until a sufficient predetermined proximal force is applied to the flexible connecting member to override a restriction force and free it from being restricted.

2. The device of claim 1 , wherein the flexible connecting member comprises a first suture.

3. The device of claim 1 , wherein the flexible connecting member is restricted by a first opening in the second member.

4. The device of claim 3 , wherein the first opening has a configuration to frictionally engage the flexible connecting member.

5. The device of claim 3 , wherein the second member has a second opening larger than the first opening, the second opening non-contiguous with the first opening.

6. The device of claim 1 , wherein the second end is not secured to the first member.

7. The device of claim 6 , wherein the second member has a second opening larger than a first opening, the second opening non-contiguous with the first opening.

8. The device of claim 7 , wherein the second opening allows unrestricted movement of the flexible connecting member.

9. The device of claim 8 , wherein the flexible connecting member loops through the first and second openings.

10. The device of claim 1 , wherein the first member, second member and flexible connecting member are composed of a resorbable material.

11. The device of claim 1 , wherein the second member is pivotable between a more longitudinal orientation for delivery and a transverse position for placement.

12. A hole closure device for 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 hole closure device comprising:
a first member having a first width in a delivery position and in a placement position;
a second member; and
a flexible connecting member having a first end and a second end, the flexible connecting member operatively connecting the first member and the second member, the first member secured to the second end of the flexible connecting member and the first member is free from the first end of the flexible connecting member, wherein pulling the first end of the flexible connecting member advances the first member toward the second member, wherein the flexible connecting member is restricted in movement by engagement of any one of the plurality of contiguous regions along its length by the second member, the flexible connecting member is freed from its restriction of movement upon application of a sufficient proximal force to a first end of the flexible connecting member, and is restricted by engagement of any one of the plurality of regions along its length when the application of sufficient force ceases, the application of sufficient proximal force pulls the first end of the flexible connecting member proximally.

13. The device of claim 12 , wherein the flexible connecting member has an intermediate portion positioned between the first end and the second end, and the intermediate portion loops through the second member.

14. The device of claim 13 , wherein the flexible connecting member loops through first and second openings in the second member.

15. The device of claim 12 , wherein movement of the flexible connecting member is restricted within a first opening in the second member.

16. The device of claim 15 , wherein the first opening in the second member has a configuration to frictionally engage the connecting member.

17. The device of claim 16 , wherein the second member has a second opening to allow unrestricted movement of the connecting member.

18. The device of claim 17 , wherein the first and second openings extend through a top surface and a bottom surface of the second member.

19. The device of claim 12 , wherein the flexible connecting member has a uniform diameter at the plurality of contiguous regions engageable with the second member.
