Prosthetic material for living organ

Abstract

The object is to provide a prosthetic material for a living organ, which can withstand the venous pressure satisfactorily, can prevent the leakage of blood or the rupture of blood vessels, can serve as a scaffold for the regeneration of a blood vascular tissue, and does not need further surgery or the like. Thus, disclosed is a prosthetic material for a living organ, which comprises a laminate composed of a film layer comprising a bioresorbable material and a porous layer comprising a bioresorbable material.

Description

Repair materials for biological organs Technical field The present invention relates to a prosthetic material for biological organs capable of withstanding arterial pressure, preventing blood leakage or rupture of blood vessels, becoming a stent for vascular tissue regeneration, and requiring no reoperation. Background technique Left heart dysplasia syndrome is a disease of imperfect formation of blood vessels from the left ventricle to the aortic valve and aorta. It is the disease with the highest mortality rate and difficult treatment in the current pediatric cardiovascular surgery. In addition, aortic arch stenosis and severing disease are diseases in which the middle of the aorta is extremely narrowed or a part of the aorta is severed. These children with congenital heart disease are characterized by defects in the blood vessels of the aorta. Therefore, the following surgical procedures are currently performed: using other arteries that are less important than the aorta (...

AI Technical Summary

Problems solved by technology

However, especially when the prosthetic material for biological organs made of these non-absorbable materials is used for children, there is a big problem that the blood vessels in the part filled with the prosthetic material for biological organs cannot grow as the child grows. Sufficient growth, or very high likelihood of healing or calcification, necessitating reoperation for replacement
