Abstract

The invention discloses a branching type aortal vascular stent system comprising an aortal vascular stent and three branch arterial vascular stents, wherein a concave part is formed in the middle section of the aortal vascular stent, and provided with three side holes; and the three branch arterial vascular stents are separately mounted in the three side holes. The branching type aortal vascular stent system is capable of isolating aortal lesion involving the aortic arch and the ascending aorta, reestablishing the blood flow of the branch artery and avoiding the customization of the stent; and the branching type aortal vascular stent system is suitable for batch production and can be used for emergency operations.

Description

technical field [0001] The invention relates to an aortic stent vascular system, in particular to a branched aortic stent vascular system. Background technique [0002] Thoracic aortic aneurysm and aortic dissection are aortic lesions that seriously threaten the life of patients. If not treated in time, the tumor size of thoracic aortic aneurysm will increase, leading to rupture and death; aortic dissection may rupture, leading to death, and at the same time, aortic dissection can lead to branch arterial ischemia, liver and kidney failure, and paraplegia , Serious complications such as lower limb dysfunction. In some cases, thoracic aortic aneurysms and aortic dissections require emergency surgery. [0003] With the development of endovascular technology, Thoracic Endovascualr Aortic Repair (TEVAR) has become the main method for the treatment of thoracic aortic aneurysm and aortic dissection. It puts a stent in the thoracic aorta, isolates the aortic lesion from the stent...
