Embodiment Construction

[0027] The interventional artificial heart valve proposed by the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0028] Before describing the present invention in detail, the main principles and ideas of the present invention will be described here. For minimally invasive interventional treatment, the stent of the interventional artificial heart valve of the present invention can expand and contract in the radial direction. Afterwards, it can be stretched rapidly, so that it can fit closely with the target tissue and form a sufficient blood flow channel; the structure of...

Abstract

The invention provides an involved artificial heart valve prosthesis.A support of the involved artificial heart valve prosthesis sequentially comprises a first sub-support, a second sub-support and a third sub-support connected in sequence.The first sub-support is a net pipe in a cone frustum shape, the second sub-support is a cylindrical net pipe, and the third sub-support is a trumpet-shaped net pipe.The maximum pipe diameter of the first sub-support is the same as the pipe diameter of the second sub-support.The minimum pipe diameter of the third sub-support is the same as that pipe diameter of the second sub-support.Due to the fact that the first sub-support is designed as the net pipe in the cone frustum shape, compared with an existing support designed as a cylindrical net pipe, the length of the support is reduced through the structure of the first sub-support, and harm caused by the fact that a too long part of the support punctures into the surrounding heart tissue to the heart is avoided.In addition, due to the fact that barbs with a locating function are arranged on the first sub-support, it is avoided that the involved artificial heart valve prosthesis shifts after being released; meanwhile, the structure is matched with the surrounding tissue, a blocking structure can be conveniently formed through membranae tectoria, perivalvular leakage can be avoided, and the success rate of an operation is increased.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an interventional artificial heart valve. 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. [0003] The mitral valve is located between the left atrium and the left ventricle, like a one-way valve, ensuring blood flows from the left atrium to the left ventricle and through a certain flow. The mitral valve complex is a functionally and anatomically complex group of devices generally considered to include the annulus, leaflets, chordae, and papillary muscles. The function of the mitral valve depends on the integrity of its physiological structure. When the normal m...
