Abstract
Abstract A system for establishing an anastomotic passageway between first and second structures within an animal, the first and second structures each having an intima-exposing opening comprises a first plate sized and configured for attachment to the opening of the first structure, the first plate including an attaching portion having means for gripping first structure at its opening, the first plate further including a coupling portion which is positioned exterior of the first structure when the first plate is attached to the first structure; a second plate sized and configured for attachment to the opening of the second structure, the second plate including an attaching portion having means for gripping the second structure at its opening, the second plate further including a coupling portion which is positioned exterior of the second structure when the second plate is attached to the second structure; and means for connecting the coupling portion of said first plate with the coupling portion of said second plate.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
168 words
A system for establishing an anastomotic passageway between first and second structures within the body of an animal, the first and second structures each defining an opening with exposed intima, the system comprising: a first plate sized and configured for attachment to the intima of the first structure, said first plate including an attaching portion having means for gripping the first structure at its intima, said first plate further including a coupling portion which is positioned exterior of the first structure when said first plate is attached to the first structure; a second plate sized and configured for attachment to the intima of the second structure said second plate including an attaching portion having means for gripping the second structure at its intima, said second plate further including a coupling portion which is positioned exterior of the second structure when said second plate is attached to the second structure; and means for connecting the coupling portion of said first plate with the coupling portion of said second plate.
Claim 2
Independent Claim
168 words
A system for establishing an anastomotic passageway between first and second structures within the body of an animal, the first and second structures each defining an opening with exposed intima, the system comprising: a first plate sized and configured for attachment to the intima of the first structure, said first plate including an attaching portion having means for gripping the first structure at its intima, said first plate further including a coupling portion which is positioned exterior of the first structure when said first plate is attached to the first structure; a second plate sized and configured for attachment to the intima of the second structure said second plate including an attaching portion having means for gripping the second structure at its intima, said second plate further including a coupling portion which is positioned exterior of the second structure when said second plate is attached to the second structure; and means for connecting the coupling portion of said first plate with the coupling portion of said second plate.
Claim 3
Dependent Claim
53 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 1 wherein the attaching portion of each of said first and second plates includes a base and a portion connected with the base for extending interior of the body and engaging the intima of the body.
Claim 4
Dependent Claim
39 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 2 wherein the attaching portion of each of said first and second plates include a plurality of legs extending from the base.
Claim 5
Dependent Claim
55 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 3 wherein each of said first and second plates has an open position whereby the base and the legs extend therefrom together to define a trough sized to receive therein a portion of the structure at the opening.
Claim 6
Dependent Claim
41 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 4 wherein the legs are deformable between the open position and a clamped position in which the structure is gripped by the attaching portions.
Claim 7
Dependent Claim
49 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 5 wherein the legs of each of said first and second plates include ends which are sized and configured to be extended into the structure and to engage with the intima therein.
Claim 8
Dependent Claim
37 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 6 wherein the end of each leg is configured with a pointed spike to grip the intima of the structures.
Claim 9
Dependent Claim
62 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 1 wherein said connecting means includes a connector having a first means for connecting with the coupling portion of said first plate and a second means for connecting with the coupling portion of said second plate to couple said first plate with said second plate.
Claim 10
Dependent Claim
48 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 1 wherein said plates and connecting means are sized and configured to establish the anastomotic passageway and wherein the first structure is a vessel and the second body is an organ.
Claim 11
Dependent Claim
48 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 1 wherein said plates and connecting means are sized and configured to establish the anastomotic passageway and wherein the first structure is a vessel and the second structure is a vessel.
Claim 12
Dependent Claim
39 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 10 wherein the first structure is the left anterior descending artery (LAD) and the second structure is the internal mammary artery (IMA).
Claim 13
Dependent Claim
27 words
The system for establishing an anastomotic passageway between first and second structures within an animal of claim 1 said first plate is identical to said second plate.
