Abstract

A seamless prosthetic valve comprising a continuous tubular member having an outer abluminal surface, a triple walled intermediate portion, and at least a first valve leaflet that is configured to selectively restrict fluid flow through the valve, the triple walled intermediate portion being formed by everting a first end of member over the member, whereby a double walled end is formed, and reverting the first end over the double walled end of the member, the first valve leaflet being formed by suturing the triple walled intermediate portion at a first commissure connection point.

Description

technical field [0001] The present invention relates generally to prosthetic valves for replacing defective cardiovascular valves. More particularly, the present invention relates to a seamless tubular extracellular matrix (ECM) prosthetic valve for replacing defective aorta, pulmonary artery, Cube, tricuspid and / or peripheral venous valves. Background technique [0002] As is well known in the art, the human heart has four valves that control the circulation of blood through the human body. On the left side of the heart are the mitral valve and the aortic valve, the mitral valve is located between the left atrium and left ventricle, and the aortic valve is located between the left ventricle and the aorta. These two valves direct oxygenated blood from the lungs to the aorta for distribution through the body. [0003] But the tricuspid valve, located between the right ventricle and right atrium, and the pulmonary valve, located between the right ventricle and the pulmonary...
