To eliminate any possibility of damaging intima of a blood vessel by holding the blood vessel using a suction force by a negative pressure, hold an anastomotic site of the blood vessel in an opened state, surely and easily anastomose blood vessels to each other, and suitably apply to a cut-back graft particuarly in a coronary-artery bypass surgery.
This blood vessel holder includes a blood vessel holding member 1 holding the blood vessel in a lumen, and a suction force transmission means 2 communicated with the lumen, the blood vessel holding member 1 has one end 11a having an approximately C-cross-section tubular shape with a slit 112 and the other end 11b having a planar cross section or an approximately C-shape with a slit gentler than the said C-cross-section, and the slit 112 is connected from one end to the other end and the slit width has a part 112b expanding to the other end direction.
