Left atrial appendage occlusion device

Abstract

The invention provides a left atrial appendage occlusion device. The left atrial appendage occlusion device includes an occlusion support and a pushing hollow pipe; the occlusion support includes a support body and a connection portion, and the connection portion is arranged on the support body; the connection portion has a first conveying channel, and a first connection end and an output end which are positioned on two ends of the first conveying channel; the pushing hollow pipe has a second conveying channel, and a second connection end and an input end which are arranged on two ends of thesecond conveying channel; the second connection end matches the first connection end; and when the first connection end and the second connection end are connected, the first conveying channel and thesecond channel communicate with each other and are used for conveying a filler to the interior of a left atrial appendage via the input end and the output end. The filler is added in the left atrialappendage via the first conveying channel arranged on the occlusion support and the second conveying channel in the pushing hollow pipe, and then the filler is converted into a solid state, and the left atrial appendage is full with the filler; and the filler can flexibly adapt to various left atrial appendages, and then the left atrial appendage occlusion device has an excellent occlusion effect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a left atrial appendage occlusion device. Background technique [0002] Atrial fibrillation (abbreviated as atrial fibrillation) is the most common clinical sustained arrhythmia, 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, which leads to complications such as stroke and peripheral vascular embolism after the thrombus falls off, which significantly increases the disability and mortality rates. 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 appendage, and ...
