Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a bracket for occluding body cavities and a left atrial appendage occluder. The problem of failure, on the other hand, solves the problem of closure failure caused by the tails of the left atrial appendage occluder being entangled and entangled under complex stress fields (such as the inner cavity of the human body).

Abstract

The invention relates to a stent for plugging a body cavity and a left auricle plugging device. The left auricle plugging device comprises the stent, and the stent is provided with a head part and a tail part which are opposite; the tail part comprises a plurality of bulges, and the farthest ends of any two adjacent bulges are on different cross sections. The stent has the advantages that the problem that the tail of the stent is tangled is solved, it is guaranteed that the stent can be successfully released in the conveying process, and after being released, the stent can effectively plug the body cavity.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bracket for blocking a body cavity and a left atrial appendage occluder. Background technique [0002] Atrial fibrillation ("AF" for short) is the most common clinically sustained heart rhythm, which has the risk of inducing ischemic stroke, so the prevention of atrial fibrillation is of great significance. Recent studies have shown that closure of the left atrial appendage can effectively prevent the risk of ischemic stroke caused by atrial fibrillation. [0003] The occluders used for left atrial appendage occlusion in the prior art can be basically divided into two categories: one is a cage-shaped occluder represented by Watchman. The fixed hook is fixed to the left atrial appendage to achieve fixation. The feature is that the skeleton part is integrally formed and easy to process; the other type is the split occluder represented by LAmbre, which is characterize...
