Embodiment Construction

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] In each embodiment of the present invention, the "far" and "near" refer to the operator. For example, the "distal end" of the first catheter refers to the end of the first catheter away from the operator, whereas the "proximal end" of the first catheter refers to the end of the first lumen close to the operator.

[0036] The embodiments of the present application provide a cardiac coronary venous blood flow occlusion device...

Abstract

The invention provides a cardiac coronary venous vascular exclusion device, and relates to the field of medical devices. The exclusion device includes a first catheter and a first sacculus. A proximalconnection part of the first catheter is connected to a filling mechanism; the first sacculus has an accommodation space therein; the first sacculus is communicated with the distal end of the first catheter; and the filling mechanism makes the first sacculus to be in a filling state through the first catheter. The device is placed in the vein to push the blood in the vein back into the cardiac muscle, thus avoiding myocardial ischemia caused by the inability of continuously supplying blood to the cardiac muscle due to arterial microvascular obstruction. By pushing the blood back to the cardiac muscle from the vein, the myocardial blood supply is guaranteed, and myocardial damage caused by no reflow is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a heart coronary vein blood flow blocking device. Background technique [0002] Coronary circulation is to provide the heart itself with the nutrients and oxygen it needs, and to remove metabolic waste. It is a circulation in which blood flows directly from the coronary artery at the base of the aorta to the capillary network inside the myocardium, and finally flows back to the right atrium and right ventricle from the vein, and then enters the lungs for exchange and then flows into the left atrium and left ventricle. Stenosis or obstruction of coronary arteries in the coronary circulation can result in myocardial ischemia, hypoxia or necrosis. [0003] Acute myocardial infarction is myocardial necrosis caused by acute and persistent coronary ischemia and hypoxia. Clinically, there are often severe and persistent retrosternal pains, which cannot be completely relieved by rest and...
