An assembled aortic stent system

Abstract

The invention discloses an assembled large aortic stent system, comprising a plurality of stent segments, each stent segment including a coating, a mesh stent is arranged along the outer side of the coating, and between the mesh stents of adjacent stent segments The connection is carried out through a buckle assembly; the buckle assembly includes a connection buckle 90 and a connection buckle tenon, and the connection buckle tenon can be inserted into the connection buckle 90 to realize a snap connection. The assembled large aortic stent can greatly improve the applicability of the traditional large stent structure to the characteristics of aortic lesions of individual patients, and achieve precise and individualized treatment of different aortic diseases.

Description

technical field [0001] The invention belongs to the technical field of vascular stents, and in particular relates to an assembled large aortic stent system. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] Aortic disease mainly includes aortic aneurysm and aortic dissection. Aortic aneurysm is a pathological change in which the diameter of the aorta is greater than 50% of the normal diameter due to local expansion of the aorta due to various reasons. Aortic dissection is due to local damage of the aortic intima, high-pressure blood flow into the blood vessel wall, resulting in a tear in the media, and the complete aortic wall structure is divided into two, forming a dissection cavity. In the minimally invasive interventional treatment technology utilizing the principle of endoluminal isolation, a covered stent is usually used to isolate aortic aneurysm or aor...

AI Technical Summary

Problems solved by technology

[0005] At present, large aortic stents are produced in limited models in the manufacturer's factory, but the inventors found that in the clinical application process, the existing stent models often cannot meet the patient's lesion characteristics, and it is necessary to customize the stent in advance in the factory. Waiting for several months, and many patients cannot wait for a long custom-made stent due to urgent conditions, which leads to on-site modification or the use of mismatched stents in their actual surgical treatment, which often results in poor postoperative results The phenomenon
