ARTIFICIAL CARDIAC BLOOD VESSEL

摘要

PROBLEM TO BE SOLVED: To provide an extensible artificial cardiac blood vessel for solving the problem that blood vessels and a valved patch cannot follow the growth of the pulmonary artery and that the heart valve cannot function sufficiently since its form and the directivity of extension/contraction are not suitable for biological tissues.

SOLUTION: The cardiac blood vessel has a blood vessel wall part which has a sheet body having directivity in extensibility as constitution element. That is, artificial cardiac blood vessel has cloth having directivity in extensibility and a valve having directivity in extensibility.
