Abstract

The invention discloses an ascending aortic stent graft, and relates to the field of medical instruments. The ascending aortic stent graft includes a stent, a cover at least partially covering the stent and a valve leaflet for reconstructing an aortic valve, and the valve leaflet is disposed at a proximal end of the stent and connected with the stent and the cover. The ascending aortic stent graftis provided with the valve leaf for reconstructing the aortic valve adapted to allowing blood from a left ventricle to flow into aortas and preventing the blood from flowing back from the aortas to the left ventricle; the stent graft is provided with two windows adapted to being aligned with two coronary artery openings. Therefore, for aortic root lesions involving both an aortic sinus and the aortic valve, minimally invasive endovascular treatment can be used for implanting the ascending aortic stent graft into an ascending aortic root, which repairs the ascending aortas, and reconstructs the aorta valve, the aortic sinus and the coronary artery openings, and the goal of integrated healing is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device suitable for treating ascending aortic dissection and aortic aneurysm involving the aortic sinus, coronary ostia, aortic valve, aortic valve stenosis or insufficiency with aortic aneurysm and other ascending aortic stent grafts. Background technique [0002] Aortic dissection refers to the high-speed and high-pressure blood flow in the aorta entering the media-adventitia or the junction of the media-adventitia through the intimal tear on the aortic wall, thereby forming a true and false aortic cavity, and expanding along the aortic axis , can lead to aortic rupture or branch artery ischemia (myocardial infarction, cerebral infarction, visceral or lower extremity ischemia), etc., is one of the most serious diseases involving the aorta. Previous studies have made statistics on the dissection of different parts of the aorta according to the location of the proximal...
