Problems solved by technology

Therefore, if the prosthetic valve through the stent is implanted, the original mitral valve's interaction with the left ventricle contraction will be lost, and there is a risk of reduced cardiac function.

Embodiment Construction

[0055] Hereinafter, the form for implementing this invention is demonstrated using drawing. The present invention is not limited to the aspects described below, and includes those that are appropriately modified from the following aspects within the range clearly understood by those skilled in the art.

[0056] figure 1 It is a conceptual diagram showing an example of the artificial heart valve of the present invention. figure 1 (a) shows an external view. figure 1 (b) Conceptual diagram showing the first leaflet. figure 1 (c) Conceptual diagram showing the second leaflet. figure 1In the example shown, the leaflet fixing part 2 is a ring 3 and is used for the mitral valve. The leaflet fixing part 2 is fixed to the leaflet so that the first leaflet and the second leaflet can be kept above the heart valve (in the atrium). In addition, the leaflet fixing part 2 can be stably arranged and held in the atrium by being connected to the atrium wall. For example, since the ring h...

Abstract

The issue of the invention is to provide an artificial heart valve capable of aiding the functions of the mitral valve of a patient in a minimally invasive manner. The artificial heart valve 1 includes a valve leaflet securing part 2 and valve leaflets (a first valve leaflet 5 and a second valve leaflet 7), wherein the valve leaflets are connected to the valve leaflet securing part 2 at the top portion of the artificial heart valve 1, the valve leaflets each have a region which narrows in width toward the bottom of the leaflet, and the artificial heart valve is an artificial mitral valve or anartificial tricuspid valve.

Description

technical field [0001] The present invention relates to artificial heart valves. More specifically, the present invention relates to a medical artificial heart valve which is provided near the mitral valve or the tricuspid valve and assists the function of the mitral valve or the tricuspid valve. Background technique [0002] Mitral valve insufficiency is a disease in which the closing function of the mitral valve is impaired, and a part of the blood flowing from the left ventricle to the aorta flows backward to the left atrium. For example, in mitral valve insufficiency, functional mitral valve insufficiency (FMR) is a disease that causes blood reflux due to function reduction or deformation of the left ventricle or left atrium, regardless of whether the mitral valve itself is normal. . [0003] For example, Japanese Patent No. 5392539 describes a stentless artificial mitral valve and an artificial heart valve for treating mitral valve insufficiency. This artificial mitr...
