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 th
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.
What is claimed is: 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 sec
What is claimed is: 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. 2. The method of claim 1, wherein said connecting is performed before said creating. 3. The method of claim 1, wherein at least part of said connecting is performed simultaneously with at least part of said creating. 4. The method of claim 1, further comprising providing a cutter; wherein said creating includes moving said cutter relative to the wall of the second vessel. 5. The method of claim 4, wherein said cutter includes a projection extending therefrom, and wherein said moving causes said projection to engage the wall of the second vessel. 6. The method of claim 5, wherein said moving includes sliding. 7. The method of claim 4, further comprising providing an anvil; and inserting at least part of said anvil through the wall of the second vessel into the lumen of the target vessel, wherein said moving is performed relative to said anvil. 8. The method of claim 7, wherein said anvil includes a channel defined therein, and wherein said moving includes moving said cutter along said channel. 9. The method of claim 1, wherein said connecting includes deploying a plurality of connectors through an end of the first vessel and into the wall of the second vessel. 10. The method of claim 9, wherein said connectors are staples. 11. The method of claim 9, wherein said deploying includes deploying at least one said connector at a different time than at least one other connector. 12. The method of claim 9, further comprising, before said connecting, making at least one incision at one end of the first vessel to create at least one flap; and placing each flap against the outer surface of the wall 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. 14. The method of claim 13, wherein said cutter includes a projection extending therefrom, and wherein said moving causes said projection to engage the wall of the second vessel. 15. The method of claim 14, wherein said moving includes sliding. 16. The method of claim 14, wherein said projection has a sharp edge configured to engage the wall of the second vessel. 17. The method of claim 14, wherein said actuating including flexing at least part of said cutter. 18. The method of claim 13, further comprising providing an anvil; and inserting at least part of said anvil through the wall of the second vessel into the lumen of the second vessel, wherein said moving is performed relative to said anvil. 19. The method of claim 18, wherein said anvil includes a channel defined therein, and wherein said moving includes moving said cutter along said channel. 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. 21. The method of claim 20, further comprising providing a cutter and placing at least part of said cutter in the lumen of the target vessel; wherein said creating includes moving said cutter. 22. The method of claim 21, wherein said moving includes sliding. 23. The method of claim 21, wherein said cutter includes a projection extending therefrom, and wherein said moving causes said projection to engage the wall of the second vessel. 24. The method of claim 23, wherein said projection has a sharp edge configured to engage the wall of the second vessel. 25. The method of claim 21, wherein said actuating including flexing at least part of said cutter. 26. The method of claim 21, further comprising providing an anvil; and inserting at least part of said anvil through the wall of the target vessel into the lumen of the target vessel, wherein said moving is performed relative to said anvil. 27. The method of claim 26, wherein said anvil includes a channel defined therein, and wherein said moving includes moving said cutter along said channel. 28. The method of claim 26, further comprising penetrating the wall of the target vessel with said anvil at a second location spaced apart from said first location. 29. The method of claim 28, wherein the distal end of said anvil is sharp, and wherein said penetrating comprises pushing said sharp distal end of said anvil through intact tissue of the wall of the target vessel.
