Abstract

The application discloses a ventricular volume reduction device that can be expanded or stretched into a strip shape. The ventricular volume reduction device includes a first bracket and a second bracket with the axes coinciding with each other. The first bracket includes a closed first connecting end and an expanded first edge. The first bracket is gradually expanded along a direction from the first connecting end to the first edge. The second bracket includes a closed second connecting end and an expanded second edge. The second bracket is gradually expanded along a direction from the secondconnecting end to the second edge. The first edge is connected with the second edge, and the first bracket is rotatable around the connecting part of the first edge and the second edge. The first connecting end is provided with a first connecting member, and the second connecting end is provided with a second connecting member. The first connecting member and the second connecting member are respectively used for connecting a delivery system. At least one surface of the first bracket and the second bracket is covered with a flow blocking membrane. The application further provides a delivery system that achieves accurate operation and recycling.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a ventricular volume reduction device and a delivery system thereof. Background technique [0002] Coronary atherosclerotic heart disease is a heart disease caused by atherosclerotic lesions in the coronary arteries that cause stenosis or blockage of the vessel lumen, resulting in myocardial ischemia, hypoxia or necrosis. It is usually called coronary heart disease. Coronary heart disease is a serious disease that threatens human life and health, and is an important cause of death from cardiovascular diseases. In the United States, there are more than 6 million patients with symptomatic coronary heart disease, and 1.5 million people suffer from myocardial infarction every year. At present, there are more than 500,000 new patients with myocardial infarction every year in my country, and it is in a significant rising stage. [0003] 20% to 50% of patients with m...
