27. A method of performing a vascular anastomosis comprising:
-
a) providing a vascular anastomosis stent device comprising i) a biocompatible elongated tube structure comprising a first and second open end, the tube structure having an inside surface facing a central axis of the tube structure and an outside surface facing away from the central axis, wherein the inside surface of the elongated tube is continuous between the first and second open end; ii) a first metallic ring encircling the tube structure at or near the first open end; and iii) a second metallic ring encircling the tube structure at or near the second open end; b) serially dilating the lumen of the bisected vessel; c) inserting the vascular anastomosis stent device into the dilated lumen of the bisected vessel such that the first and second metallic rings reside within the dilated vessel lumen on opposing sides relative the bisection; d) applying a first ring clip or ligature around the outside of the vessel at a location over the first metallic ring; and e) applying a second ring clip or ligature around the outside of the vessel at a location over the second metallic ring. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
