Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a left atrial appendage occluder with strong adaptability. On the one hand, it solves the problem that the existing left atrial appendage occluder will still cause thrombus when there is a gap between the left atrial appendage and the left atrial appendage. On the other hand, it solves the problem that the large size of the existing occluder causes the delivery sheath to be thick and easy to cause damage to human blood vessels

Abstract

The invention relates to the technical field of medical devices, in particular to a left atrial appendage occluder with strong adaptability. The left atrial appendage occluder includes a occluding disc, an anchoring part, and a connecting part connecting the occluding disc and the anchoring part; the opening of the left atrial appendage is blocked by a occluding disc, wherein the setting of the supporting disc frame and the blocking membrane , compared with other metal braided occlusion discs, the contraction volume is smaller and lighter, and the flow-blocking membrane is used to prevent blood from entering and exiting the left atrial appendage; especially the unique design of the cuff, specifically, the cuff is set on the supporting disc frame On the peripheral support ring, the cuff is filled with elastic material during the operation. When the cuff matches the left atrial appendage orifice, the elastic and flexible cuff filled with elastic material can adapt to the irregular shape of the left atrial appendage orifice and completely seal it. Blocking the opening of the left atrial appendage solves the problem that traditional blocking devices cannot solve the problem of lax closure of the opening of the left atrial appendage in different cases, and completely eliminates the hidden danger of thrombosis in the left atrial appendage caused by atrial fibrillation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a left atrial appendage occluder with strong adaptability. Background technique [0002] In the field of cardiovascular and cerebrovascular medicine, atrial fibrillation is the most common clinical persistent arrhythmia. Atrial fibrillation leads to thromboembolism, which in turn leads to symptoms such as palpitations, chest tightness, and dizziness. The biggest hazard is stroke, which can be fatal or severe. Disabling, seriously affecting people's health and quality of life. Therefore, stroke prevention is the fundamental goal of AF treatment. [0003] The left atrial appendage (LAA) is an important part of the origin of thromboembolism in patients with atrial fibrillation (AF). 60% of patients with rheumatic heart disease and atrial fibrillation have cardiogenic thrombus from the left atrial appendage. Patients with non-valvular atrial fibrillation More than 90% of th...
