Abstract
A blood stream adjuster is arranged inside a blood vessel for bypass made of autologous blood vessel, artificial blood and so on when the blood vessel for bypass is transplanted between two blood vessels of the human body. The blood stream adjuster comprises a stricture portion which is located at its axis direction center part and has a smaller inside diameter in comparison with the inside diameters of axis direction both ends. The inside diameter of the stricture portion is set so that quantity, velocity or pressure of blood stream will be suitable for the blood vessel with which the side to receive blood stream in the blood vessel for bypass is anastomosed. Hereby, the occurrence of stricture and obstruction is restrained around the anastomotic portion between the blood vessel for bypass and its anastomotic blood vessel.
