The anastomosis device of claim 7, wherein each vessel has an intimal layer, and wherein the holding surfaces of each ring are positioned to capture vessel tissue in an everted configuration so that when the rings are in an anastomosis position the intimal layer of the portion of the first vessel defining a first vessel opening contacts the inimal layer of the portion of the second vessel defining a second vessel opening. 12. The paired anastomosis device of claim 7, wherein each vessel has an adventitial layer, wherein the holding surfaces of the first ring contact the adventital surfaces of the portion of the first vessel defining a first vessel opening, and wherein the holding surfaces of the second ring contact the adventital surfaces of the portion of the second vessel defining a second vessel opening. 13. The anastomosis device of claim 7, wherein each ring comprises a plurality of flexible segments.14. The anastomosis device of claim 13, wherein each flexible segment comprises two adjoining arms in a V-shaped configuration.15. The anastomosis device of claim 13, wherein
