Abstract
Abstract An anastomosis system and method uses an anvil to control and support a tissue site during an anastomosis procedure. The anvil is particularly useful for supporting a wall of a coronary artery during attachment of a graft vessel to the coronary artery because the wall of the coronary artery is very thin, difficult to grasp, and susceptible to tearing. In one method, the anvil is inserted into a pressurized or unpressurized target vessel and is pulled against an inner wall of the target vessel causing tenting of the thin tissue of the vessel wall. A graft vessel is then advanced to the anastomosis site and an end of the graft vessel is positioned adjacent and exterior of the target vessel. Staples are inserted through the tissue of the graft vessel and the target vessel by pivoting the arms of a staple holder towards the anvil. When the ends of the staples engage staple bending features on the anvil, the ends of the staples bend over securing the graft vessel and target vessel together. After stapling is complete, an incision is formed in the wall of the target vessel to allow blood flow between the target vessel and the graft vessel.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
104 words
A method of performing anastomosis between a graft vessel and a target vessel, comprising: inserting an anvil into the target vessel through an anvil entrance hole, wherein upon insertion said anvil is positioned at least partially within the lumen of the target vessel; supporting the wall of the target vessel with said anvil; securing the graft vessel to the target vessel with a plurality of discrete connectors, said securing performed at a location on the target vessel spaced apart from the anvil entrance hole a distance not substantially greater than the length of said anvil; and removing said anvil from the anvil entrance hole.
Claim 2
Independent Claim
104 words
A method of performing anastomosis between a graft vessel and a target vessel, comprising: inserting an anvil into the target vessel through an anvil entrance hole, wherein upon insertion said anvil is positioned at least partially within the lumen of the target vessel; supporting the wall of the target vessel with said anvil; securing the graft vessel to the target vessel with a plurality of discrete connectors, said securing performed at a location on the target vessel spaced apart from the anvil entrance hole a distance not substantially greater than the length of said anvil; and removing said anvil from the anvil entrance hole.
Claim 3
Dependent Claim
11 words
The method of claim 1 , wherein said connectors are staples.
Claim 4
Dependent Claim
30 words
The method of claim 1 , further comprising creating an opening in the wall of the target vessel to allow fluid flow between the graft vessel and the target vessel.
Claim 5
Dependent Claim
24 words
The method of claim 3 , further comprising a cutter moveable relative to said anvil, wherein said creating is performed by moving said cutter.
Claim 6
Dependent Claim
17 words
The method of claim 3 , wherein the anvil entrance hole is spaced apart from the opening.
Claim 7
Dependent Claim
19 words
The method of claim 1 , wherein substantially no leakage occurs through the anvil entrance hole after said removing.
Claim 8
Dependent Claim
16 words
The method of claim 1 , wherein said creating is performed from inside the target vessel.
Claim 9
Independent Claim
85 words
A method of performing anastomosis between a graft vessel and a target vessel, comprising: placing an end of the graft vessel against the side of the target vessel at a first location; inserting an anvil through the side of the target vessel at a second location adjacent to said first location; deploying a plurality of connectors to secure the graft vessel to the target vessel; and creating an opening in the target vessel to allow fluid flow between the graft vessel and the target vessel.
Claim 10
Independent Claim
85 words
A method of performing anastomosis between a graft vessel and a target vessel, comprising: placing an end of the graft vessel against the side of the target vessel at a first location; inserting an anvil through the side of the target vessel at a second location adjacent to said first location; deploying a plurality of connectors to secure the graft vessel to the target vessel; and creating an opening in the target vessel to allow fluid flow between the graft vessel and the target vessel.
Claim 11
Dependent Claim
20 words
The method of claim 8 , wherein said inserting comprises pressing said anvil through the side of the target vessel.
Claim 12
Dependent Claim
16 words
The method of claim 8 , wherein said second location is upstream from said first location.
Claim 13
Dependent Claim
11 words
The method of claim 8 , wherein said connectors are staples.
Claim 14
Dependent Claim
21 words
The method of claim 8 , wherein said deploying includes bringing at least one said connector into contact with said anvil.
Claim 15
Dependent Claim
26 words
The method of claim 8 , further comprising a cutter moveable relative to said anvil, wherein said creating comprises incising the target vessel with said cutter.
Claim 16
Dependent Claim
16 words
The method of claim 8 , wherein said creating is performed from inside the target vessel.
