Abstract

A 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 device includes a covering member positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture. A securing member is positionable external of the vessel and has a plurality of pores extending therethrough. A flexible connecting member operatively connects the covering member and securing member and moves the securing member toward the covering member.

Claims

1. A 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 device comprising:

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

a securing member positionable external of the vessel, the securing member having a plurality of pores;

a first flexible connecting member operatively connecting the covering member and the securing member, the first flexible connecting member being fixedly secured to the securing member at one end, wherein the first flexible connecting member moves the securing member toward the covering member as a second end of the first flexible connecting member is moved proximally as the securing member remains fixedly secured to the first flexible connecting member at the first end, in a placement position the securing member securing the covering member in position and remaining proximal of the covering member

a second flexible connecting member operatively connecting the covering member and the securing member, the second flexible connecting member being fixedly secured to the securing member at one end, wherein the second flexible connecting member moves the securing member toward the covering member as a second end of the second flexible connecting member is moved proximally as the securing member remains fixedly secured to the second flexible connecting member at the first end, wherein the second flexible connecting member is looped through the covering member.

2. The device of claim 1, wherein the covering member has a first opening, the first opening configured to restrict movement of the first flexible connecting member.

3. The device of claim 1, wherein the covering member is composed of a resorbable material.

4. The device of claim 3, wherein the first flexible connecting member is a suture and is composed of a resorbable material.

5. The device of claim 1, wherein the covering member has a substantially planar surface.

6. The device of claim 1, wherein the securing member is composed of a resorbable material.

7. The device of claim 1, wherein the securing member is composed of a mesh.

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

9. The device of claim 1, wherein the covering member has a length greater than a width.

10. The device of claim 1, wherein a central region of the covering member is thicker than a peripheral region.

11. The device of claim 1, wherein the covering member has first and second openings, the first flexible connecting member extending through the first and second openings, the first opening configured to frictionally retain the first flexible connecting member to retain the position of the securing member with respect to the covering member.

12. The device of claim 1, wherein the covering member has first and second openings to receive the first flexible connecting member, the first opening having a size different than a size of the second opening.

13. A 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 device comprising:

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

a securing member positionable external of the vessel, the securing member having a plurality of pores; and

a flexible connecting member operatively connecting the covering member and the securing member, the flexible connecting member being fixedly secured to the securing member at one end, wherein the flexible connecting member moves the securing member toward the covering member as a second end of the flexible connecting member is moved proximally as the securing member remains fixedly secured to the flexible connecting member at the first end, in a placement position the securing member securing the covering member in position and remaining proximal of the covering member;

wherein the covering member has first and second openings to receive the flexible connecting member, the first opening having a size different than a size of second opening and has third and fourth openings to receive a second connecting member, the third opening having different size than the fourth opening.

14. The device of claim 13, further comprising a second flexible connecting member operatively connecting the covering member and the securing member, the second flexible connecting member being fixedly secured to the securing member at one end, wherein the second flexible connecting member moves the securing member toward the covering member as a second end of the second flexible connecting member is moved proximally as the securing member remains fixedly secured to the second flexible connecting member at the first end.

15. The device of claim 14, wherein the second flexible connecting member is looped through the covering member.

16. The device of claim 13, wherein the first and third openings frictionally engage a respective flexible connecting member and the third and fourth openings are dimensioned for free unrestricted movement of the respective flexible connecting member.

17. The device of claim 16, wherein the third opening has a larger cross-sectional dimension than the first opening and the fourth opening has a larger cross-sectional dimension than the second opening.
