Abstract

A percutaneously insertable system for sealing punctures in blood vessels includes an element that is percutaneously insertable into and deplorable within a blood vessel, a thread-like member attached to the element that passes through the wall of the blood vessel and arresting element moveable on the thread and into engagement with the other surface of the blood vessel thereby to seal the opening.

Claims

1. A sealing device for percutaneously sealing a percutaneously made puncture in a blood vessel having a vessel wall with inner and outer wall surfaces, said sealing device comprising a first element which is constructed and arranged to be percutaneously inserted into the blood vessel;

a fixation attachment connected to the first element, said first element being repositionable after insertion into the blood vessel to engage against the inner wall surface, and a second element constructed and arranged to be inserted percutaneously and be moved over the fixation attachment toward and adjacent the wall of the blood vessel and into cooperative relation with said first element about said puncture in said blood vessel to thereby seal the puncture in the blood vessel.

2. A sealing device in accordance with claim 1 wherein the first element comprises a sealing element.

3. A sealing device in accordance with claim 1 whereby said second element comprises an elongate sealing element which is to be received through the blood vessel wall.

4. A sealing device in accordance with claim 1 wherein said second element comprises an inflatable sealing element.

5. A sealing device in accordance with claim 1 whereby the fixation attachment comprises a thread.

6. A sealing device in accordance with claim 4 wherein at least one of the elements and the fixation attachment are of a bio-resorbable material.

7. A sealing device in accordance with claim 6 whereby the bio-resorbable material comprises collagen.

8. A sealing device in accordance with any one of claims 6 or 7 whereby the bio-resorbable material comprises surgical suturing material.

9. A sealing device in accordance with claim 4 wherein said first element is a sealing element and essentially sheet-like and circular.

10. A sealing device in accordance with claim 4 wherein the first element is a sheet-like element, the fixation attachment being located essentially in the center of the sheet-like element.

11. A sealing device in accordance with claim 4 wherein said first element is a sealing element and essentially sheet-like and heart-shaped.

12. A sealing device in accordance with claim 4 wherein said first element is a sealing element and essentially sheet-like and oval.

18. A sealing device in accordance with claim 1 wherein said second element comprises an expandable sealing element.

19. A sealing device in accordance with claim 3 wherein at least one of the elements and the fixation attachment is of a bio-resorbable material.

20. A sealing device in accordance with claim 3 wherein said first element is a sealing element and essentially sheet-like and circular.

21. A sealing device in accordance with claim 3 wherein the first element is a sheet-like element, the fixation attachment being located essentially in the center of the sheet-like element.

22. A sealing device in accordance with claim 3 wherein said first element is a sealing element and essentially sheet-like and heart-shaped.

23. A sealing device in accordance with claim 3 wherein said first element is a sealing element and essentially sheet-like and oval.

13. A method for percutaneously sealing a percutaneously made puncture in a blood vessel wall comprising:

providing a sealing device comprising a first element constructed and arranged to be percutaneously inserted into the blood vessel through the blood vessel wall;

a fixation attachment connected to the first element and a second element constructed and arranged to be inserted percutaneously and be moved over the fixation attachment toward and into engagement with the blood vessel, comprising the steps of;

percutaneously inserting the first element into the interior of the blood vessel with the fixation attachment extending through the puncture in the blood vessel wall; and

moving the second element over the fixation attachment toward and at least partially received within the puncture in the blood vessel wall and defining, between said first and second elements, a seal for the puncture.

14. The method of claim 13 wherein said second element is tubular.

15. The method of claim 13 wherein said second element is an inflatable sealing element.

16. The method of claim 15 wherein said step of moving said second element with toward said blood vessel wall comprises the step of inflating said second element.

17. The method of claim 13 including the step of expanding said second element.

24. In the sealing of a percutaneously made puncture in a blood vessel having inner and outer vessel wall surfaces, a sealing device adapted to seal a percutaneously made puncture, said sealing device comprising a first element constructed and arranged to be received within said blood vessel and in engagement with the inner wall surface thereof, a fixation attachment connected to the first element, and a second element constructed and arranged to be moved over the fixation attachment immediately outward of said first element and in fixed position engagement with said vessel wall and at least partially within said puncture and in mutually retaining relation with said first element for stabilization of said sealing device at and to said blood vessel wall.

25. The sealing device of claim 24 wherein said second element is of a length as to project outwardly from said blood vessel to a distance exterior thereof.

26. The sealing device of claim 24 wherein said second element is a flow-precluding inflatable element engageable with the exterior surface of said blood vessel wall about said puncture.

27. The sealing device of claim 24 wherein said second element is a flow-precluding expandable element engageable with the exterior surface of said blood vessel wall about said puncture.

28. A method for percutaneously sealing a percutaneously made puncture in a blood vessel wall comprising:

providing a sealing device comprising a first element constructed and arranged to be percutaneously inserted into the blood vessel through the blood vessel wall;

a fixation attachment connected to the first element and a second element constructed and arranged to be inserted percutaneously and be moved over the fixation attachment toward and into engagement with the blood vessel, comprising the steps of;

percutaneously inserting the first element into the interior of the blood vessel with the fixation attachment extending through the puncture in the blood vessel wall;

moving the second element over the fixation attachment toward and into engagement with the outside surface of the blood vessel wall, expanding said second element and defining, between said first and second elements, a seal for the puncture.
