Abstract

The invention provides a left auricle occluder and occluding device. The left auricle occluder comprises an occluding structure and a guiding structure; and the guiding structure is used for positioning a pushing structure to the occluding structure, is located in the occluding structure and can be pulled out from the occluding structure, and the near end of the guiding structure is exposed out ofthe near end of the occluding structure. The guiding structure can guide the pushing structure after the pushing structure is separated from the occluding structure and when the pushing structure needs to be connected with the occluding structure, thus the pushing structure can be very easily connected with the occluding structure again, and repositioning is carried out.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a left atrial appendage occluder and a left atrial appendage occluder. 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 cardiogenic thrombus from the left atrial a...
