摘要
The present invention provides a base material which can be formed into valved lumen shape tissue having an ampulla and a leaflet consisting of body tissue. Specifically, the base material includes a first column 5 that forms an upstream tubular section 4 of a blood vessel 3, a second column 7 that forms a downstream tubular section 6 of the blood vessel 3, a plurality of bulges 10 for forming an ampulla 8 and a leaflet 9 of the blood vessel 3, and engagement means 11 that causes the bulge 10 to engage the first column 5 and/or the second column 7. The engagement means 11 includes recesses 15a and 15b in axial end surfaces of one or both of the first column 5 and the second column 7, and an engagement section 18 that overhangs from a bulge body 17 and engages the recesses. An outer peripheral surface of the body 17 of the bulge 10 is an ampulla forming surface 20, and a gap provided between the bulge body 17 and the first column 5 and/or the second column 7 is a leaflet forming section 22. 展开▼
