Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0022] figure 2 It is an exploded view of a left atrial appendage occluder whose occluding surface is absorbable material according to the present invention, image 3 It is a schematic diagram of a left atrial appendage occluder whose occluding surface is absorbable material according to the present invention, please refer to figure 2 and image 3 As shown, a preferred embodiment of the left atrial appendage occluder whose occluding surface is absorbable material is shown, which includes a fixed disk 2, which is formed by a number of wires 21, and the fixed disk 2 is provided with several Outwardly extending barbs 22.

[0023] In a preferred embodiment, the fixed disk 2 is braided by several elastic metal wires 21 to form a conventional shape such as a disk or a column. The barbs 22 are al...

Abstract

The invention discloses a left auricle occluder with an occluding surface made of an absorbable material. The left auricle occluder comprises: a fixing disc, wherein the fixing disc is formed by a plurality of metal wires, and the fixing disc is provided with a plurality of barbs extending outwards; an occluding disc, wherein the occluding disc is made of a bioabsorbable material; and a flow choking film, wherein the flow choking film is made of a bioabsorbable material, and the flow choking film is arranged in the occluding disc in the radial direction. A plurality of brackets extending outwards are arranged at the near end of the fixing disc, and the fixing disc is connected to the occluding disc through the brackets. By using the left auricle occluder, after the left auricle occluder isoccluded on the left auricle, the occluding disc and the flow choking film can be partially or completely degraded and absorbed, so that the risks of allergy, inflammation, metal fatigue fracture andthe like possibly caused by high metal content in a human body are effectively reduced. Meanwhile, through the use of the brackets, the metal brackets are used for effectively rebounding and restoring the occluding disc to the preset shape and fixing the occluding disc to the corresponding part of the left auricle.

Description

technical field [0001] The invention relates to the technical field of heart surgery medical instruments, in particular to a left atrial appendage occluder whose occluding surface is made of absorbable materials. Background technique [0002] Atrial fibrillation (AF) is the most common persistent cardiac arrhythmia clinically, and the incidence rate of atrial fibrillation in the general population is 0.5% to 1.3%. The main hazard of atrial fibrillation is the promotion of thrombus formation. After the thrombus falls off, it is easy to cause complications such as stroke and peripheral vascular embolism, which significantly increases the disability rate and mortality rate. Stroke is the most common and most harmful complication of atrial fibrillation. About 15 million people worldwide suffer from stroke every year, of which 20% to 25% are attributed to atrial fibrillation. Studies have shown that 60% of patients with rheumatic heart disease and atrial fibrillation have cardio...
