BASE MATERIAL FOR FORMING ARTIFICIAL BLOOD VESSEL WITH VALVE, METHOD FOR PRODUCING ARTIFICIAL BLOOD VESSEL WITH VALVE USING THE SAME, AND ARTIFICIAL BLOOD VESSEL WITH VALVE

摘要

PROBLEM TO BE SOLVED: To provide a base material allowing the formation of an artificial blood vessel with a valve which includes an enlarged part and the valve which are formed of biological tissue, a method for producing the artificial blood vessel with the valve using the base material, and the artificial blood vessel with the valve.;SOLUTION: The base material 1 for forming the artificial blood vessel with the valve includes a first columnar body 5 forming an upstream tubular part 4 of the blood vessel 3; a second columnar body 7 forming a downstream tubular part 6 of the blood vessel 3; a plurality of bulging bodies 10 forming the enlarged part 8 with a blood vessel wall bulging radially outward and valve lobes 9; and locking means 11 for locking the bulging bodies 10 to the first columnar body 5 and/or the second columnar body 7. The locking means 11 includes recesses 15a, 15b formed at one or both axial end faces of the first columnar body 5 and second columnar body 7 and recessed in the axial direction, and a locking part 18 projecting radially inward from a bulging body 17 and locked to the recess. The outer peripheral surface of the body 17 of the bulging body 10 serves as an enlarged part forming surface 20, and a clearance provided between the bulging body 17 and the first columnar body 5 and/or the second columnar body 7 forms a valve lobe forming part 22.;COPYRIGHT: (C)2012,JPO&INPIT
