Abstract

A device to seal an incision in a blood vessel includes an inner member and an outer member. A suture connects the inner member and the outer member. A first portion of the suture is embedded within a second portion of the suture such that as tension in the suture increases the first and second portions are held together.

Claims

1. A device to seal an incision in a blood vessel, comprising:

an inner member;

an outer member; and

a suture connected to the inner member and the outer member, wherein a first portion of the suture is embedded within a second portion of the suture such that as tension in the suture increases the first and second portions are held together.

2. A device as set forth in claim 1, wherein the inner member comprises a seal.

3. A device as set forth in claim 1, wherein the outer member comprises a seal.

4. A device as set forth in claim 1, wherein the outer member comprises a plug.

5. A device as set forth in claim 1, wherein a third portion of the suture is embedded within a fourth portion of the suture such that as tension in the suture increases the third and fourth portions are held together.

6. A device as set forth in claim 5, further comprising glue to secure different portions of the suture together.

7. A device as set forth in claim 1, wherein the first portion comprises at least one suture loop.

8. A device as set forth in claim 1, wherein the first portion comprises at least two suture loops.

9. A device as set forth in claim 1, further comprising a third portion around the second portion such that as tension in the suture increases the second and third portions are held together.

10. A device as set forth in claim 5, wherein the second portion and the fourth portion are configured to retain the outer member in place when the outer member is slid over the second portion and the fourth portion.

11. A device as set forth in claim 1, wherein the suture further comprises a third portion of the suture embedded within the second portion of the suture such that as tension in the suture increases the first, second, and third portions are held together.

12. A device as set forth in claim 1, wherein the inner member comprises an anchor.

13. A device as set forth in claim 1, wherein the outer member comprises a locking element.

14. A device as set forth in claim 1, wherein ends of the suture are secured such that the ends do not stick out from the suture arrangement.

15. A device as set forth in claim 1, wherein the first portion and the second portion are configured to help retain the outer member in place when the outer member is slid over the first portion and the second portion.
