a vascular stent

Abstract

The invention discloses a vascular stent and belongs to the technical field of implanted medical devices and aims at solving the problem that an existing vascular stent has large contact area with the inner wall of a blood vessel, often damages the inner wall of the blood vessel, causes thrombosis and is high in restenosis rate. The vascular stent comprises a first S-shaped stent and a second S-shaped stent, wherein the first S-shaped stent is hinged to the second S-shaped stent, the first S-shaped stent comprises a first front section, a first rear section and a first limiting nail for connecting the first front section and the first rear section, and the second S-shaped stent comprises a second front section, a second rear section and a second limiting nail for connecting the second front section and the second rear section. By adopting the vascular stent, the contact area between the vascular stent and the inner wall of the blood vessel is effectively decreased, the blood vessel inner wall damage probability is reduced, and the restenosis occurrence probability of the blood vessel is reduced.

Description

technical field [0001] The invention belongs to the technical field of implantable medical devices, in particular to a blood vessel stent. Background technique [0002] Vascular stent refers to the placement of internal stents in the diseased segment on the basis of lumen balloon expansion to support the stenotic and occluded segment of the vessel, reduce elastic recoil and reshaping of the vessel, and maintain smooth blood flow in the lumen. Some internal stents can also prevent restenosis. Mainly divided into coronary stents, cerebrovascular stents, renal artery stents, aortic stents, etc. [0003] However, due to the large contact area between the existing vascular stent and the inner wall of the blood vessel, damage to the inner wall of the blood vessel often occurs, resulting in thrombosis and a high rate of restenosis. Contents of the invention [0004] The purpose of the present invention is to provide a vascular stent to solve the problem that the existing vascul...
