Abstract

The present invention provides a medical device comprising a left atrial appendage occluder, a stent delivery member, a fixing portion and a fixed delivery member; the stent delivery member has a first channel and a first connection end disposed at the distal end of the first channel , the left atrial appendage occluder comprises a bracket body and a bracket connector arranged on the bracket body, the bracket connector has a second channel and a second connection end arranged on the second channel; the first and second The connecting ends are combined so that the first and second channels are connected to form a push channel, and the distal end of the fixed conveying member is combined with the fixed part, so that the fixed conveying part drives the fixed part into the preset area in the push channel, so as to Connect the LAA occluder to the preset area. The medical device of the present invention helps the left atrial appendage occluder to easily achieve repeated positioning and recovery, and neither damages the sheath nor the problem of fixation failure caused by the anchor thorn falling off due to contact with the sheath. Improve the safety of surgery.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical 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 more than 90% of patients wi...
