The invention provides a left atrial appendage blocking device, which includes a blocking stent and a pushing hollow tube. The blocking stent includes a stent body and a connecting part. The connecting part is provided on the stent body, and the connecting part has a first delivery channel. and a first connecting end and an output end located at both ends of the first conveying channel. The push hollow tube has a second conveying channel and a second connecting end and an input end disposed at both ends of the second conveying channel. The second connecting end is connected to the first When the first connection end and the second connection end are connected, the first delivery channel is connected with the second delivery channel, and is used to deliver filler to the inside of the left atrial appendage through the input end and the output end. The present invention fills the filler into the left atrial appendage by blocking the first delivery channel on the stent and pushing the second delivery channel in the hollow tube. Subsequently, the filler is converted into a solid state and fills the entire left atrial appendage. Since the filler can be flexible It is adaptable to various left atrial appendages, so the blocking effect is good.
Description
Technical field [0001] The present invention relates to the technical field of medical devices, and in particular to a left atrial appendage blocking device. Background technique [0002] Atrial fibrillation (abbreviated as atrial fibrillation) is the most common sustained arrhythmia in clinical practice. The incidence of atrial fibrillation in the general population is 0.5% to 1.3%. The main hazard of atrial fibrillation is the promotion of thrombosis, which can lead to complications such as stroke and peripheral vascular embolism after the thrombus breaks off, significantly increasing the disability and mortality rates. Stroke is the most common and 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 cardiogenic thrombi in patients with atrial fibrillation from rheumatic heart disease originate from the left atrial appendage, ...
