First Claim
Patent Images
1. A method for performing end-to-end anastomosis between a first tissue structure and a second tissue structure, comprising:
- making at least two incisions extending from the edge at the end of each tissue structure, each in a generally longitudinal direction;
wherein said making creates at least two flaps at the end of each tissue structure;
bringing each flap of the first tissue structure into contact with a corresponding flap of the second tissue structure; and
connecting each flap of the first tissue structure to a corresponding flap of the second tissue structure.

Abstract
A method for performing anastomosis connects two tissue structures, such as blood vessels, end-to-end. At least two flaps may be created at the end of each tissue structure. Each flap of one tissue structure may be brought into contact with a corresponding flap of the other tissue structure. The corresponding flaps may be connected, such as by deploying one or more connectors therethrough.

9. A method for performing end-to-end anastomosis between a first tissue structure and a second tissue structure, comprising:
-
cutting an end of the first tissue structure at an angle to its longitudinal centerline, wherein the resultant cut has a length; cutting an end of the second tissue structure at an angle to its longitudinal centerline, wherein the resultant cut has a length substantially equal to the length of the cut in the first tissue structure; making at least two incisions extending from the edge at the end of each tissue structure, each in a generally longitudinal direction;
wherein said making creates at least two flaps in an end of each tissue structure; andbringing the cut ends of the first tissue structure and the second tissue structure together, wherein said bringing moves each flap of the first tissue structure into contact with a corresponding flap of the second tissue structure. - View Dependent Claims (10, 11, 12, 13)

14. A method for connecting an end of a first tissue structure to an end of a second tissue structure, comprising:
-
providing a tool; making two generally longitudinal incisions extending from the edge of an end of each tissue structure, the incisions substantially one hundred and eighty degrees apart from one another with regard to the circumference of the tissue structure, resulting in two flaps at an end of each tissue structure; holding each flap with said tool; and actuating said tool with a single motion, said single motion both bringing the flaps of the first tissue structure into contact with the flaps of the second tissue structure and connecting the flaps of the first tissue structure to the flaps of the second tissue structure. - View Dependent Claims (15, 16, 17)
