Embodiment 1

[0061] This example 1 provides a heart valve adjustable auxiliary device 100, according to Figure 1-5 , 12. The adjustable auxiliary device mainly includes an annular support 10 arranged near the annulus tissue 300 and / or the atrial wall 400 of the human body, and a blocking member 30 arranged in the middle of the annular support 10 . Specifically, it includes an annular support 10 , a plurality of connecting elements 20 and an occluding member 30 ; the annular support 10 and the occluding member 30 are capable of radially collapsing and expanding between a radially collapsed configuration and a radially expanded configuration.

[0062] The annular support 10 has an expandable annular mesh structure, which can be anchored to the annulus tissue 300 and / or the atrial wall 400 of the human body; specifically, it is preferably a rhombic mesh structure, so as to be folded into the catheter 41 . It preferably includes a single layer of diamond-shaped grids distributed around, and m...

Embodiment 2

[0087] Embodiment 2 provides different specific structures of the blocking member 30, mainly reflected in the difference in the adjustment mechanism, and brings about the difference in the adjustment method and effect. according to Figure 7A with 7B , on the basis of Embodiment 1, the adjustment mechanism further includes a radial adjustment mechanism 35, and the radial adjustment mechanism 35 is used to apply a radial force to the frame structure 31, thereby adjusting the shape of the frame structure 31. The radial adjustment mechanism 35 preferably includes a push rod and a spiral telescopic rod. The spiral telescopic rod passes through the fixing part 33 and is fixedly connected to the radial adjustment coupling part 332 on the outer surface of the fixing part 33 . The roughly axial telescopic movement produced by the spiral telescopic rod acts on the push rod. Since the push rod has a hinge fixed point, the axial telescopic movement of the spiral telescopic rod is transf...

Embodiment 3

[0094] In Example 3, according to Figure 9 , the adjustment mechanism includes a balloon 36 placed in the frame structure 31, the balloon 36 has a fluid channel 333 passing through the fixture 33; the balloon 36 can be filled and released with fluid to adjust the height of the frame structure 31 and / or shape, to achieve the adjustment of the shape of the matching surface on the blocking member 30. Fluids include gases or liquids, preferably contrast media.

[0095] The upper end of the balloon 36 is fixed to the fixing member 33 , and the connection between the balloon 36 and the fixing member 33 communicates with the fluid channel 333 . The fluid channel 333 is connected to operating equipment, such as a balloon 36 inflation pressure pump, through the fluid conduit 41 . After the balloon 36 is expanded, the collapsed frame structure 31 can be stretched out to achieve the desired height, radial size and shape. In another embodiment, the frame structure 31 is made of a shap...

Abstract

The invention relates to a heart valve adjustable auxiliary device and system. The heart valve adjustable auxiliary device comprises an annular supporting piece, a plurality of connecting elements and a plugging piece, the annular supporting piece is provided with an expandable annular net-shaped structure and can be anchored to human body valve ring tissue and / or an atrium wall, the annular supporting piece and the plugging piece are connected through the plurality of the connecting elements, the plugging piece can be kept in an area roughly defined by the annular supporting piece through the plurality of the connecting elements, the plugging piece is used for providing a matching surface in mutual contact with a human valve leaflet, the plugging piece comprises a frame structure, a fixing piece fixed to one side of the inflow end of the frame structure, a flexible covering piece covering the frame structure and at least one adjusting mechanism arranged in the frame structure, the adjusting mechanism is used for adjusting the height and / or shape of the frame structure. The auxiliary device and system are small in damage to the human body, good in durability and capable of effectively relieving mitral valve or tricuspid valve reflux. The size and shape of the plugging piece can be adjusted in a multi-dimensional mode so as to meet the requirements of different patients.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an adjustable assisting device and system for a heart valve. Background technique [0002] Heart valves are membrane-like structures that can open and close in the organs of humans or certain animals. Each human heart has four valves, the aortic valve connecting the left ventricle to the aorta, the pulmonary valve connecting the right ventricle to the pulmonary artery, the mitral valve connecting the left atrium to the left ventricle, and the mitral valve connecting the right atrium to the right ventricle. tricuspid valve. They all act as one-way valves, so that blood can only flow from one direction to the other and not back. [0003] Mitral regurgitation is a heart condition in which the leaflets of the mitral valve fail to coapt shut under peak systolic pressure, causing abnormal leakage of blood from the left ventricle into the left atrium. There are a number of structural f...
