Abstract

The invention provides a valved conduit and a method for making the valved conduit. The valved conduit comprises a tubulous body, and at least three valve cusps which are respectively sewed to the inner side of the tubulous body, wherein the upper edge of each valve cusp is separated from the tubulous body, the side edge of each valve cusp and the tubulous body are in sewed connection, and a valvepocket is formed between each valve cusp and the tubulous body; and the depth of the valve pocket is determined based on the minimum connecting line length of two end points at the upper edge of eachvalve cusp on the tubulous body. The valved conduit is connected between the right ventricle and the lung, and the opening of the valve pocket faces the lung; when the right ventricle is in contraction, blood output from the right ventricle flows to the lung through a blood flow passage between the valve cusps; and when the right ventricle is in diastole, the blood flow passage is closed, so thatreflowing blood flows in the valve pocket having certain depth. Therefore, the scheme can relieve the problem of blood reflow during diastole of the right ventricle.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a valve-bearing pipeline and a method for making the valve-bearing pipeline. Background technique [0002] Between the heart and the lungs is the pulmonary artery, which carries venous blood through the right ventricle to the lungs. [0003] At present, in the surgical treatment of many complex heart diseases, polymer material pipelines and artificial biological pipelines are usually used to replace the pulmonary artery to reconstruct the pulmonary artery and the right ventricular outflow tract of the heart. [0004] When the right ventricle contracts, venous blood can flow to the lungs through the artificial biological pipeline. However, when the right ventricle is diastolic, ordinary polymer material pipes and artificial biological pipes are prone to blood backflow, resulting in right ventricular insufficiency. Contents of the invention [0005] The invention provides a pi...
