<P>PROBLEM TO BE SOLVED: To provide a pin which fixes a bio-indwelling article to a tissue easily and securely in the blood-flow region of a living body. <P>SOLUTION: A pin 5 has a head part 51, a puncturing part 52 extending and protruding from the end 511 of the head part 51, and a backbone part 53 extending and protruding from halfway the head part 51. The head part 51 of pin 5 is in the shape of a bar and nearly straight. The puncturing part 52 is bar-shaped and straight. When the puncturing part 52 pierces a blood vessel wall together with a graft, the graft is fixed at the blood vessel wall. The backbone part 53 is bar-shaped and curved or bent so that the side of the puncturing part 52 can dent. The axis 520 of the puncturing part 52 is inclined with the axis 510 of the head part 51 so that an angle θ between these axes 520 and 510 may be 90° or less. <P>COPYRIGHT: (C)2010,JPO&INPIT |
