Abstract
Abstract Anastomotic stents for connecting a graft vessel to a target vessel, and methods of use thereof. The anastomotic stents of the invention are suitable for use in a variety of anastomosis procedures, including coronary artery bypass grafting. One embodiment of the invention comprises a large vessel anastomotic stent for use with large diameter target vessels such as the aorta or its major side branches. Another embodiment of the invention comprises a small vessel anastomotic stent for use on a target vessel which has a small diameter such as a coronary artery. Another aspect of the invention involves applicators for use with the stents of the invention.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
76 words
An anastomosis tool for use in connecting an end of a graft vessel to the side of a target vessel, the tool comprising a vessel penetrating member configured to penetrate the target vessel, wherein said vessel penetrating member is located outside the lumen of the graft vessel at all times, and wherein the tool is configured to penetrate the target vessel and deliver a one-piece anastomosis device to connect the graft vessel to the target vessel.
Claim 2
Dependent Claim
76 words
An anastomosis tool for use in connecting an end of a graft vessel to the side of a target vessel, the tool comprising a vessel penetrating member configured to penetrate the target vessel, wherein said vessel penetrating member is located outside the lumen of the graft vessel at all times, and wherein the tool is configured to penetrate the target vessel and deliver a one-piece anastomosis device to connect the graft vessel to the target vessel.
Claim 3
Dependent Claim
25 words
The anastomosis tool of claim 1 , wherein the anastomosis tool further comprises at least two concentric tubes configured for deploying the one-piece anastomosis device.
Claim 4
Dependent Claim
26 words
The anastomosis tool of claim 1 , wherein the concentric tubes are configured for movement with respect to one another to deploy the one-piece anastomosis device.
Claim 5
Dependent Claim
20 words
The anastomosis tool of claim 2 , wherein the vessel penetrating member is configured for positioning inside the concentric tubes.
Claim 6
Independent Claim
113 words
A method of performing anastomosis between a graft vessel and a target vessel, each having a lumen therein, the method comprising: providing a one-piece anastomosis device; receiving said anastomosis device on an anastomosis device applicator having a vessel penetrating member; connecting a graft vessel to said anastomosis device on said anastomosis device applicator, wherein said anastomosis device applicator is outside the lumen of the graft vessel; creating an opening in the target vessel with the vessel penetrating member of the anastomosis device applicator; advancing said anastomosis device into the penetration in the target vessel; and deploying said anastomosis device with the anastomosis device applicator to connect the graft vessel to the target vessel.
Claim 7
Independent Claim
113 words
A method of performing anastomosis between a graft vessel and a target vessel, each having a lumen therein, the method comprising: providing a one-piece anastomosis device; receiving said anastomosis device on an anastomosis device applicator having a vessel penetrating member; connecting a graft vessel to said anastomosis device on said anastomosis device applicator, wherein said anastomosis device applicator is outside the lumen of the graft vessel; creating an opening in the target vessel with the vessel penetrating member of the anastomosis device applicator; advancing said anastomosis device into the penetration in the target vessel; and deploying said anastomosis device with the anastomosis device applicator to connect the graft vessel to the target vessel.
Claim 8
Dependent Claim
35 words
The method of claim 5 , wherein the step of deploying said anastomosis device is performed by moving two tubes of the anastomosis device applicator with respect to one another to deploy said anastomosis device.
Claim 9
Dependent Claim
15 words
The method of claim 5 , wherein said anastomosis device is a one-piece anastomosis device.
Claim 10
Dependent Claim
22 words
The method of claim 5 , wherein during the penetrating step the vessel penetrating member is positioned inside the anastomosis device applicator.
Claim 11
Dependent Claim
25 words
The method of claim 5 , wherein the step of deploying connects an end of the graft vessel to a side of the target vessel.
Claim 12
Independent Claim
98 words
A method of performing anastomosis between a graft vessel and a target vessel, the method comprising: providing a one-piece anastomosis device; receiving said anastomosis device on an anastomosis device applicator including a first tube and a second tube substantially coaxial with the first tube; connecting a graft vessel to said anastomosis device on the anastomosis device applicator with an end of the graft vessel passing out a side hole of at least one of the first and second tubes; and deploying said anastomosis device with the anastomosis device applicator to connect the graft vessel to the target vessel.
Claim 13
Independent Claim
98 words
A method of performing anastomosis between a graft vessel and a target vessel, the method comprising: providing a one-piece anastomosis device; receiving said anastomosis device on an anastomosis device applicator including a first tube and a second tube substantially coaxial with the first tube; connecting a graft vessel to said anastomosis device on the anastomosis device applicator with an end of the graft vessel passing out a side hole of at least one of the first and second tubes; and deploying said anastomosis device with the anastomosis device applicator to connect the graft vessel to the target vessel.
Claim 14
Dependent Claim
28 words
The method of claim 10 , wherein the step of deploying said anastomosis device is performed by moving the first and second tubes with respect to one another.
Claim 15
Dependent Claim
46 words
The method of claim 10 , wherein the step of receiving said anastomosis device on the anastomosis device applicator is performed by removably connecting a plurality of features of said anastomosis device to a plurality of connecting members at a distal end of the first tube.
