Device and method for establishing an artificial arterio-venous fistula

An intravascular connector, comprising:

• a first pair of clinch members comprising a first member and an apposed second member;
• a second pair of clinch members opposite from the first pair of clinch members and comprising a first member and an apposed second member;
• wherein the first and second pairs of clinch members has a deployed configuration longitudinally disposed relative to contiguous portions of a first vessel and a second vessel such that the first and second pairs of clinch members are biased to close upon contiguous parallel portions of the first and second vessels,
• wherein the first member of the first and second pair of clinch members each have a length less than each second member of the first and second pair of clinch members such that each first member is deployed on opposite ends of the connector within the first and second vessels, respectively, and each individual clinch member is deployable sequentially in a predetermined order within the first vessel and second vessel, and
• wherein each first member is sized to arc entirely within each respective vessel into its deployed position when each second member contacts each respective vessel wall.
