PURPOSE: A structure for blood vessel anastomosis using a self expandable material or structure and a blood vessel anastomosis method using the same are provided to perform blood vessel anastomosis operation more easily, by fixing blood vessel by expanding the blood vessel anastomosis structure by applying an external constant stimulus. CONSTITUTION: An injection nozzle(9) is arranged to be located in the outside of a blood vessel. A pair of elastic members(10, 10') are extended from one side of the injection nozzle. The pair of elastic member is located in the diameter of the blood vessel between both ends of the cut blood vessel. The elastic member is filled with materials(11, 11') having expansibility. Both ends of the blood vessel are sutured using prolene as suture thread. |
