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. According to certain embodiments, the second portion is not part of a first suture portion, and both the first and second portions are used to retain the outer member in place. A method of making such a device is also described.

Claims

1. A device to close an incision, comprising:

an inner member;

an outer member; and

a first suture connected to the inner member and the outer member;

at least one suture portion, which is embedded in a portion of the first suture, to retain the outer member in place when the outer member is slid over said at least one suture portion and said portion of the first suture, wherein said at least one suture portion is not part of the first suture.

2. A device as set forth in claim 1, wherein the first suture and said at least one suture portion are made from the same material.

3. A device as set forth in claim 1, wherein the first suture and said at least one suture portion are multifilament sutures.

4. A device as set forth in claim 1, wherein both ends of said at least one suture portion are substantially enclosed by the first suture.

5. A device as set forth in claim 1, further comprising a third suture portion which is embedded in said portion of the first suture.

6. A device as set forth in claim 1, wherein a portion of the first suture is embedded in itself.

7. A device as set forth in claim 1, wherein said at least one suture portion and said first suture exhibit substantially the same physical properties.

8. A device as set forth in claim 1, wherein said at least one suture portion and said first suture exhibit substantially the same resorption time.

9. A device as set forth in claim 1, wherein the inner member and outer member are configured to seal an incision in a blood vessel.

10. A method of making a device to close an incision, comprising:

providing an inner member;

threading a first suture through the inner member;

providing a second suture which is not part of the first suture;

embedding at least one suture portion of the second suture in a portion of the first suture, to enlarge an outer dimension of the first suture to a configuration such that an outer member is retained in place when the outer member is slid over said at least one suture portion and said portion of the first suture; and

cutting the second suture to shorten the second suture.

11. A method as set forth in claim 10, wherein both ends of said at least one suture portion are substantially enclosed by the first suture.

12. A method as set forth in claim 10, wherein the inner member and outer member are configured to seal an incision in a blood vessel.
