SUBSTRATE FOR FORMING ARTIFICIAL VALVE AND ARTIFICIAL VALVE

摘要

The present invention provides: a substrate for forming an artificial valve, the substrate allowing a connective tissue to be easily inserted into a flap-forming space to thereby reduce the time needed for forming the flap; and an artificial valve. Specifically, a columnar substrate body 6 is provided. A plurality of concave parts 7 are formed on the external circumferential surface of the substrate body 6. A cover substrate 9 is mounted on the substrate body 6. The concave part 7 is covered with the cover substrate 9 to define a flap-forming space 8. An opening 10 for inserting the connective tissue 2 is defined between the edge of the cover substrate 9 and the rim of the concave part 7. A slit 11 is formed in the cover substrate 9 to allow communication between the flap-forming space 8 and the outside of the substrate. The slit 11 is formed parallel to a substrate central axis 15 and is long enough to reach the edge of the cover substrate 9. The substrate 1 for forming an artificial valve is placed in an environment where biological tissue material is present. The connective tissue 2 is formed on the surface of the substrate. The cover substrate 9 is pulled away from the substrate body 6 in the direction of the substrate central axis. The connective tissue 2 which is removed from the substrate is used as an artificial valve 5.
