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 use in the joining of a first tubular structure and a second tubular structure, the anastomotic device comprising:

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

an inverting member for facilitating positioning of at least a portion of the second tubular structure around at least a portion of the first tubular structure; and

a constricting member supported on the inverting member and movable onto the cylindrical sleeve to constrict at least a portion of the second tubular structure towards at least a portion of the first tubular structure and towards the cylindrical sleeve.

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

3. The anastomotic device according to claim 1, wherein at least one of the cylindrical sleeve, the constricting member and the inverting member is bio-absorbable.

4. The anastomotic device according to claim 2, wherein the cylindrical sleeve has an inner diameter and an outer diameter, wherein the outer diameter of the cylindrical sleeve is smaller than an inner diameter of the inverting member.

5. The anastomotic device according to claim 1, wherein the constricting member is a garter spring, which is configured to exert constrictive forces on at least a portion 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 tubular structure and the second tubular structure, wherein a portion of the first tubular structure is sutured about the rod and a portion of the second tubular structure is sutured about the rod.

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 cylindrical sleeve.

8. The anastomotic device according to claim 1, further comprising an ejecting member configured and adapted to move the constricting member from the inverting member to the cylindrical sleeve.

9. The anastomotic device according to claim 1, further comprising an ejecting member which facilitates positioning the spring at least partially about the first tubular structure and the second tubular structure.

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

11. A method for joining a first tubular structure to a second tubular structure, the method comprising the steps of:

providing an anastomotic device, comprising;

a cylindrical sleeve;

an inverting member;

a constricting member supported on the inverting member and movable onto the cylindrical sleeve; and

a rod configured and adapted for insertion through the cylindrical sleeve, the inverting member, the first tubular structure and the second tubular structure;

positioning the cylindrical sleeve onto a shaft portion of the rod;

positioning the cylindrical sleeve, through the second tubular structure, into the first tubular structure;

suturing a free end of the first tubular structure to the shaft portion of the rod;

suturing a free end of the second tubular structure to the shaft portion of the rod;

positioning the inverting member over the shaft portion of the rod and into the second tubular portion;

withdrawing the rod relative to the inverting member to approximate the cylindrical sleeve and the inverting member, such that at least a portion of second tubular structure is at least partially around the free end of the first tubular structure, creating a second tubular structure outer layer and an inner layer; and

moving the constricting member from the inverting member to the cylindrical sleeve such that the constricting member is positioned at least partially between the outer layer and the inner layer of the second tubular structure and outside of the first tubular structure, wherein the constricting member at least a portion of the first tubular structure and at least a portion of the second tubular structure towards the cylindrical sleeve.

12. The method according to claim 11, further comprising the step of cutting off at least a portion of the free end of the first tubular structure, at least a portion of the free end of the second tubular structure.

13. The method according to claim 11, further comprising the step of allowing at least a portion of the first tubular structure and at least a portion of the second tubular structure to become joined with one another.

14. The method according to claim 11, wherein the constricting member is a garter spring.

15. The method according to claim 11, further comprising the step of providing an ejecting member configured and adapted to facilitate positioning of the constricting member at least partially between the outer layer and the inner layer of the second tubular structure, and outside of the first tubular structure.

16. The method according to claim 11, wherein at least one of the cylindrical sleeve, the inverting member and the constricting member is bio-absorbable.

17. An anastomotic device for use in the joining of a first tubular structure and a second tubular structure, the anastomotic device comprising:

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.

18. The anastomotic device according to claim 17, further comprising an ejecting member configured and dimensioned to move the constricting member from the ejecting member to the cylindrical sleeve when the cylindrical sleeve is at least partially positioned within the bore of the inverting member.

19. The anastomotic device according to claim 17, further comprising a rod selectively positionable through the bores of the cylindrical sleeve and the inverting member, wherein the rod includes a head portion configured and dimensioned to engage a distal-most end of the cylindrical sleeve and approximate the cylindrical sleeve toward the inverting member upon a proximal displacement of the rod relative to the inverting member.

20. The anastomotic device according to claim 17, wherein at least one of the cylindrical sleeve, the inverting member and the constricting member is bio-absorbable.
