Compression anastomosis device and method
View Patent ↗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.
1. A method of joining a first tubular structure and a second tubular structure, comprising:
providing an anastomosis device comprising a first sleeve and a second sleeve;
placing the first sleeve within the first tubular structure;
placing the second sleeve within the second tubular structure;
positioning at least one of the first sleeve and the second sleeve onto a rod;
suturing a portion of the first tubular structure and a portion of the second tubular structure onto a portion of the rod;
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;
removing the second sleeve from within the second tubular structure;
withdrawing the rod such that the portions of the tubular structures that have been sutured are positioned laterally spaced from the first sleeve, and wherein the first sleeve is the only portion of the anastomosis device that remains within at least one of the first and the second tubular structures.
2. The method according to claim 1 , further comprising moving a constricting member from a position on the second sleeve to a position on the first sleeve.
3. The method according to claim 2 , wherein the constricting member is positioned around the end of the second tubular structure.
4. The method according to claim 1 , wherein the second sleeve is positioned around the first sleeve by engaging the first sleeve with the rod.
5. The method according to claim 4 , wherein the rod is moved in a direction toward the second sleeve.
6. The method according to claim 5 , wherein the first sleeve is inserted in the second sleeve.
7. The method according to claim 2 , wherein the constricting member is moved in a direction toward the first sleeve by an ejecting member.
8. The method according to claim 7 , wherein the ejecting member is disposed around the second sleeve.
9. The method according to claim 2 , wherein the constricting member is moved into a groove formed in the outer surface of the first sleeve.
