Abstract

The invention relates to a covered stent, which is used for aortic vasculopathy involving aortic arches. The covered stent can be widely applied to various people, does not need to be customized for individuals, and has a good treatment effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a covered stent. Background technique [0002] Cardiovascular disease poses a great threat to human health, especially aortic disease such as aortic aneurysm is one of the most dangerous acute and severe cardiovascular diseases. At present, the treatment methods for aortic lesions include drug therapy, surgical treatment, interventional therapy, etc. Among them, the principle of interventional therapy is: the compressible stent is delivered to the lesion in the blood vessel and released, and after the stent is expanded in the blood vessel, The diseased part is isolated from the vascular lumen, and the blood passes through the stent, thereby protecting the diseased blood vessel and achieving the purpose of repairing the diseased blood vessel. Interventional therapy has been widely used because of its small trauma, safety, and effectiveness. [0003] For aorti...
