Abstract

The invention discloses a heart valve external-stent and a heart valve prosthesis. The heart valve external-stent comprises a mesh-tube-shaped external-stent body, the external-stent body is providedwith a blood outflow end and a blood inflow end, the blood outflow end is of a waveform structure, and one or more wave peaks are bent at an interval of one or more peaks in the waveform structure tothe external-stent body to form a bending part, and the unbent wave peaks are connected with outward barbs or connected with outward barbs at intervals. According to the heart valve external-stent andthe artificial heart valve, the waveform structure is designed on the blood outflow end of the external-stent body, and the wave peaks in the waveform structure are bent inwards at intervals, an outflow end opening formed by the inward bending wave peaks is inclined to the posterior lobe of a mitral valve, the inward bending wave peaks are connected with an internal stent, a valve is arranged inan attached mode, and good fixation is ensured while an outflow tract is prevented from obstruction.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an external stent for a heart valve and an artificial heart valve. Background technique [0002] The heart is divided into two parts, left and right, each part includes a ventricle and an atrium, between the ventricle and the ventricle and between the atrium and the atrium are separated by the interventricular septum and the atrial septum, and there is a function between the atrium, the ventricle and the artery to prevent blood backflow valve. Among them, 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 aforementioned valves will open and close ...
