Abstract

An anastomotic device for use in the joining of a first tubular structure and a second tubular structure is provided. The anastomotic device includes a cylindrical sleeve configured and dimensioned for placement at least partially within the first tubular structure, the cylindrical sleeve defining a bore therethrough; an inverting member configured and dimensioned for placement at least partially within the second tubular structure, the inverting member defining a bore therethrough which is configured and dimensioned to selectively receive the cylindrical sleeve therein; and a constricting member selectively positionable on the inverting member and movable onto the cylindrical sleeve when the cylindrical sleeve is at least partially positioned within the bore of the inverting member.

Claims

1. An anastomotic device for joining a first tubular structure and a second tubular structure, the anastomotic device comprising:

a first sleeve configured and dimensioned for placement at least partially within the first tubular structure; and

a second sleeve configured and dimensioned for placement at least partially within the second tubular structure, the second sleeve being positionable around the first sleeve for positioning an end of the first tubular structure around the first sleeve and an end of the second tubular structure around the end of the first tubular structure.

2. The anastomotic device according to claim 1, wherein the first sleeve defines a bore therethrough.

3. The anastomotic device according to claim 1, wherein at least one of the first sleeve and the second sleeve is bio-absorbable.

4. The anastomotic device according to claim 1, herein the first sleeve has an outer diameter, the second sleeve has an inner diameter, and the outer diameter of the first sleeve is smaller than the inner diameter of the second sleeve.

5. The anastomotic device according to claim 1, further including a constricting member supported on the second sleeve and being positionable around the end of the second tubular structure and the end of the first tubular structure.

6. The anastomotic device according to claim 1, further comprising a rod which is configured and adapted for insertion through the first sleeve and the second sleeve.

7. The anastomotic device according to claim 6, wherein the rod comprises a distal end having a dimension larger than the inner diameter of the first sleeve.

8. The anastomotic device according to claim 5, further comprising an ejecting member configured and adapted to move the constricting member from the second sleeve onto the first sleeve.

9. The anastomotic device according to claim 1, wherein the first sleeve comprises a circumferential groove formed in an outer surface thereof.

10. A method of joining a first tubular structure and a second tubular structure, comprising:

placing a first sleeve within the first tubular structure;

placing a second sleeve within the second tubular structure; and

positioning the second sleeve around the first sleeve so that an end of the first tubular structure is positioned around at least a portion of the first sleeve and an end of the second tubular structure is positioned around the end of the first tubular structure.

11. The method according to claim 10, further comprising moving a constricting member from a position on the second sleeve to a position on the first sleeve.

12. The method according to claim 11, wherein the constricting member is positioned around the end of the second tubular structure.

13. The method according to claim 10, wherein the second sleeve is positioned around the first sleeve by engaging the first sleeve with a rod.

14. The method according to claim 13, wherein the rod is moved in a direction toward the second sleeve.

15. The method according to claim 14, wherein the first sleeve is inserted in the second sleeve.

16. The method according to claim 11, wherein the constricting member is moved in a direction toward the first sleeve by an ejecting member.

17. The method according to claim 16, wherein the ejecting member is disposed around the second sleeve.

18. The method according to claim 11, wherein the constricting member is moved into a groove formed in the outer surface of the first sleeve.
