Method of performing anastomosis
First Claim
Patent Images
1. A method for end-to-side anastomosis of a first vessel to a second vessel, each vessel having a wall surrounding a lumen, comprising:
- providing a cutter and placing said cutter inside the lumen of the second vessel;
connecting an end of the first vessel to the side of the second vessel to form a generally I-shaped junction; and
creating only one opening in the wall of the second vessel with said cutter, said creating performed by moving said cutter upward into, longitudinally along, and then downward out of the wall of the second vessel only after said placing said cutter inside the lumen of the second vessel, wherein the opening allows fluid communication between the lumen of the first vessel and the lumen of the second vessel.

Abstract
A method for anastomosing a first vessel to a second vessel may include connecting an end of the first vessel to the side of the second vessel and creating an opening in the wall of the second vessel from within the lumen of the second vessel, where that opening allows fluid communication between the lumen of the first vessel and the lumen of the second vessel.

13. A method for end-to-side anastomosis of a first vessel to a second vessel, each vessel having a wall surrounding a lumen, comprising:
-
connecting an end of the first vessel to the side of the second vessel to form a generally T-shaped junction; providing a cutter; moving at least part of said cutter into the lumen of the second vessel; and actuating said cutter only after said moving at least part of said cutter into the lumen of the second vessel;
wherein said actuating said cutter creates only a single opening in the second vessel with said cutter by moving said cutter upward into, longitudinally along, and then downward out of the wall of the second vessel, whereby said actuating brings the lumen of the first vessel and the lumen of the second vessel into fluid communication. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method for anastomosing a graft vessel to a target vessel, each vessel having a wall surrounding a lumen, comprising:
-
providing a cutter and placing said cutter inside the lumen of the second vessel; securing an end of the graft vessel to a first location on the side of the target vessel, wherein the end of the graft vessel encloses a perimeter on the side of the target vessel at said first location; and creating, with said cutter, only a single passage in the wall of the target vessel at said first location and within said perimeter, said creating performed from inside the target vessel only after said placing said cutter inside the lumen of the second vessel by moving said cutter upward into, longitudinally along, and then downward out of the wall of the second vessel, wherein said creating brings the lumen of the first vessel and the lumen of the second vessel into fluid communication through the passage. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
