Abstract

The invention discloses a support for an involvement type artificial cardiac valve and a preparation method thereof and belongs to the technical field of involvement type medical apparatus and instruments. The support is an elastic support capable of extending and contracting in the radial direction, the support comprises a tubular structure part and a skirt-shaped opening structure part, the diameter of the skirt-shaped opening structure part is larger than that of the tubular structure part, and the tubular structure part and the skirt-shaped opening structure part are fixedly connected in a coaxial mode. Due to the fact that the support is capable of extending and contracting in the radial direction, so that the support is convenient to install, convey and release in the involvement treatment, the support and a natural valve are fitted with each other in physiologic structure, the support has a certain self-location function, the support is convenient to locate and release rapidly and accurately, and displacement and perivalvular leakage are not prone to occurring after releasing.

Description

technical field

[0001] The invention belongs to the technical field of interventional medical devices, and in particular relates to a bracket of an interventional artificial heart valve and a preparation method thereof. Background technique

[0002] The heart is a very important organ of the human body, which provides power for the blood circulation of the human body. The heart is divided into two parts, the left and the right. Each part contains a ventricle and an atrium. There are valves between the atria, ventricles, and arteries that prevent blood from flowing back. The valve between the left atrium and left ventricle is the mitral valve, the valve between the right atrium and right ventricle is the tricuspid valve, the valve between the left ventricle and the aorta is the aortic valve, and the valve between the right ventricle and the aorta is the aortic valve. The valve between the pulmonary arteries is the pulmonary valve.

[0003] The above-mentioned valves will op...
