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. 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;
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, the first sleeve having an outer diameter, and the second sleeve having an inner diameter defining a bore, the outer diameter of the first sleeve being smaller than the inner diameter of the second sleeve such that the first sleeve completely is passable through the bore of the second sleeve;
a rod configured and adapted for insertion through the first sleeve and the second sleeve, wherein at least a portion of the rod receives a portion of at least one of the first tubular structure and the second tubular structure sutured therearound when the portion of the at least one of the first tubular structure and the second tubular structure is sutured to the rod, the rod having a distal end having a dimension larger than the inner diameter of the first sleeve and smaller than the inner diameter of the second sleeve, the distal end being pliable to deflect to pass through the inner diameter of the first sleeve; and
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.
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 bioabsorbable.
4. The anastomotic device according to claim 1 , further comprising an ejecting member configured and adapted to move the constricting member from the second sleeve onto the first sleeve.
5. The anastomotic device according to claim 1 , wherein the first sleeve comprises a circumferential groove formed in an outer surface thereof for receiving the constricting member.
6. The anastomotic device according to claim 1 , wherein the constricting member is in a radially expanded condition when positioned about the second sleeve.
7. The anastomotic device according to claim 6 , wherein the constricting member applies constricting forces when positioned about the first sleeve.
8. The anastomotic device according to claim 1 , wherein the constricting member is a spring.
