Problems solved by technology

[0005] At present, there are few minimally invasive transcatheter products approved in China for the treatment of secondary and tricuspid regurgitation. These products need to change the structure of the heart during the healing process. Brings a lot of pressure and incompatibility to cardiac surgery

Embodiment Construction

[0048] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the embodiments of the present application shall fall within the protection scope of the embodiments of the present application.

[0049]The "proximal end" refers to the end implanted in or close to the atrium when the self-expandable occlusion device is placed in the heart. The "distal end" refers to the end implanted in or close to the ventricle when the self-expandable occlusion device is placed in the heart.

Abstract

The invention provides a self-expanding plugging device which is used for being implanted between heart valves. The device comprises a self-expanding body which is provided with an elastic surface which extends in the circumferential direction of an axis A and forms a hollow inner cavity, a first port which is arranged at the near end of the elastic surface and circumferentially surrounds the axis A, and a second port which is arranged at the far end of the elastic surface and circumferentially surrounds the axis A, wherein the first port, the inner cavity and the second port communicate with one another, and the size of the second port is larger than that of the first port. The structure of the self-expansion plugging device is ingeniously combined with flowing of blood during cardiac systole and diastole. For a patient with heart valve reflux, the self-expansion plugging device in the systolic period can cooperate with a native valve to effectively solve the problem of blood reflux, and blocking to a blood flowing channel can be reduced in the diastolic period.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, and in particular to a self-expanding occlusion device. Background technique [0002] Mitral valve, tricuspid valve, aortic valve, pulmonary valve and other common diseases are valvular insufficiency. Taking the mitral valve as an example, during systole, part of the blood of the left ventricle flows to the left atrium through the insufficient mitral valve orifice. reflux. The left atrium receives blood from the left ventricular regurgitation and blood from the pulmonary vein at the same time, and the blood volume and pressure of the left atrium increase significantly, resulting in left atrial hypertrophy. [0003] During the diastolic period, more blood flows from the left atrium to the left ventricle, causing the left ventricle to hypertrophy due to the strengthening of contraction. After the compensation period progresses to the decompensation period, heart...
