Blood vessel anastomosing auxiliary tool

A blood vessel anastomosing auxiliary tool consisting of at least:

• a hollow conduit having openings at both ends, and having flexibility and self-restoring property for inserting into a blood vessel;
• a flexible guide wire for guiding said hollow conduit when it is inserted into a blood vessel;
• a blood leaking preventing means on the outer surface of said hollow conduit, preventing blood leaking from the space formed between the external wall of said conduit and the inner wall of the blood vessel, when the hollow conduit is inserted into a blood vessel;
• and a retrieving means for retrieving said conduit from within a blood vessel;
• and furthermore said guide wire having a higher elasticity than the blood vessel to be inserted, a width being adjustable to be inserted into the lumen of the hollow conduit, and a length being more than 1.2 times longer than the length of the hollow conduit (shaft direction).
