Embodiment 1

[0065] This example 1 provides a heart valve adjustable auxiliary device 100, according to Figure 1-4 , the adjustable auxiliary device mainly includes an annular support 10 arranged near the human annulus tissue 300 and / or the atrium wall 400 , 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.

[0066] 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 multiple stacked...

Embodiment 2

[0099] Example 2 provides a heart valve adjustable assisting device 100'. Different from Embodiment 1, Embodiment 2 provides different position adjustment mechanisms, which are mainly reflected in the differences in position adjustment methods, and bring about differences in adjustment methods and effects. The connecting element 20' has a position adjustment mechanism for adjusting the position of the blocking member 30' within the area substantially enclosed by the annular support member 10. In this embodiment, the fixing member 33' will not assume the function of position adjustment, but only have the function of adjusting the height and / or shape of the frame structure. Therefore, the size of the fixing part 33' in this embodiment can be relatively small, for example, the diameter of the disc-shaped fixing part 33' does not exceed 4mm. The adjustable auxiliary device 100' of this embodiment is easier to collapse and accommodate in the catheter 41.

[0100] according to F...

Embodiment 3

[0107] In Embodiment 3, the adjustment mechanism includes a balloon placed in the frame structure, and the balloon has a fluid channel 337 passing through the fixing member 33'; the balloon can be filled and released with fluid, so as to adjust the height of the frame structure and / or 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.

[0108] The upper end of the balloon is fixed to the fixing part 33, and the connection between the balloon and the fixing part 33' communicates with the fluid channel 337. The fluid channel 337 is connected to an operating device, such as a balloon dilation pressure pump, through a fluid tube. After the balloon is inflated, the collapsed frame structure can be stretched to achieve the desired height, radial size and shape. In another embodiment, the frame structure is made of a shape memory metal, and expansion of the balloon enables ...

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, wherein the annular supporting piece is provided with an expandable annular net-shaped structure and can be anchored to the human body valve ring tissue and / or the atrium wall; the annular supporting piece and the plugging piece are connected through the connecting elements; the plugging piece is used for providing a matching surface making contact with the human body valve leaflets; the plugging piece comprises a frame structure and a flexible covering piece covering the frame structure; and the plugging piece or the connecting elements are provided with position adjusting mechanisms used for adjusting the position of the plugging piece in the area roughly defined by the annular supporting piece. 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 regurgitation. The position of the plugging piece can be accurately adjusted, and the size and shape of the plugging piece can be adjusted 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...
