Abstract:
A method of end-to-side anastomosis of blood vessels for connecting a side portion of a first blood vessel to an end portion of a second blood vessel, comprising:holding a first site on the side portion of the first blood vessel located in the vicinity of a peripheral portion of an opening formed on the side portion of the first blood vessel using a holder, and partially elevating the side portion of the first blood vessel; superimposing a second site on the side portion of the first blood vessel on the end of the second blood vessel and fixing them to each other with a ring-shaped fixing member, the second site being more distant from the peripheral portion of the opening formed on the side portion of the first blood vessel than the first site; and detaching the holder from the first blood vessel when the first and second blood vessels are fixed by the fixing member or after they are fixed.
