At least one ring is configured to connect the first and second ports to the first and second portions of the artery or the vein by applying force about substantially the circumferential extent of the first segment of the connector and the first and second portions of the artery or the vein to join the first and second ports to the first and second portions of the artery or the vein, respectively. An AV graft assembly and method of implanting a connector for an AV graft are also disclosed. ## Claims ### Claim 1 A connector assembly for an arteriovenous (AV) graft, comprising: a connector having a first segment arranged a long a first axis having first and second opposing ports and a second segment arranged along a second axis having a third port, each of the first and second ports configured to be joined to first and second portions of an artery or a vein, respectively; and at least one ring configured to connect the first and second ports to the first and second portions of the artery or the vein by applying force about substantially the circumferential extent of the first segment of the connector and the first and second portions of the artery or the vein to join the first and second ports to the first and second portions of the artery or the vein, respectively. ### Claim 2 (depends on 1) The connector assembly of claim 1, wherein the ring includes first and second segments joined by a hinged connection. ### Claim 3 (depends on 1) The connector assembly of claim 1, wherein the at least one ring comprises a first ring at the first port and a second ring at the second port. ### Claim 4 (depends on 1) The connector assembly of claim 1, wherein the ring includes an opening configured to receive the second segment of the connector. ### Claim 5 (depends on 1) The connector assembly of claim 1, further comprising a seal arranged around at least one of the first, second, and third ports. ### Claim 6 (depends on 1) The connector assembly of claim 1, wherein an angle between the first and second axes is between 70 and 110 degrees. ### Claim 7 (depends on 6) The connector assembly of claim 6, wherein the first and second axes are perpendicular to one another. ### Claim 8 (depends on 1) The connector assembly of claim 1, wherein the connector is configured to be flattened into a low-profile operating mode. ### Claim 9 (depends on 1) The connector assembly of claim 1, further comprising a nozzle extending from the third port. ### Claim 10 An arteriovenous (AV) graft assembly, comprising: a first connector, the first connector having a first segment arranged a long a first axis having first and second opposing ports and a second segment arranged along a second axis having a third port, each of the first and second ports configured to be joined to first and second portions of an artery, respectively; a second connector, the second connector having a first segment arranged a long a first axis having first and second opposing ports and a second segment arranged along a second axis having a third port, each of the first and second ports configured to be joined to first and second portions of a vein, respectively; and an AV graft joined to the third port of each of the first and second connectors. ### Claim 11 (depends on 10) The AV graft assembly of claim 10, further comprising at least one ring configured to connect the first and second ports of the first and second connectors to the first and second portions of the artery or the vein by applying force about substantially the circumferential extent of the first segment of the connector and the first and second portions of the artery or the vein to join the first and second ports to the first and second portions of the artery or the vein, respectively. ### Claim 12 (depends on 10) The AV graft assembly of claim 10, wherein the AV graft is integral with at least one of the first and second connectors. ### Claim 13 (depends on 10) The AV graft assembly of claim 10, wherein at least one of the first and second connectors is configured to be flattened into a low-profile operating mode. ### Claim 14 (depends on 10) The AV graft assembly of claim 10, further comprising a nozzle extending from the third port of at least one of the first and second connectors. ### Claim 15 A method of implanting a connector for an AV graft, comprising: forming an opening in an artery or a vein between first and second portions of the artery or vein; arranging a connector in the opening, the connector having a first segment arranged a long a first axis having first and second opposing ports and a second segment arranged along a second axis having a third port; and joining the first and second portions of the artery or vein to the first and second ports. ### Claim 16 (depends on 15) The method of claim 15, wherein the step of forming the opening includes bisecting the artery or the vein. ### Claim 17 (depends on 15) The method of claim 15, wherein after the step of forming the opening, the first and second portions of the artery or the vein remain at least partially connected. ### Claim 18 (depends on 15) The method of claim 15, wherein joining the first and second ports to the first and second portions of the artery or vein, respectively, is accomplished by at least one ring. ### Claim 19 (depends on 18) The method of claim 18, further comprising flattening the connector into a low profile operating mode prior to the arranging. ### Claim 20 (depends on 16) The method of claim 16, wherein the AV graft includes a valve configured to control fluid flow through the AV graft, and further comprising the step of opening the valve.
