Problems solved by technology

Ordinary stents do not match the deformation characteristics of the intima of the blood vessel wall, which will cause damage to the biological tissue of the blood vessel wall, increase the risk of restenosis of the blood vessel wall, and bring uncertainties to the long-term health of the patient

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] see figure 1 and figure 2 , a chiral-antichiral mixed vascular stent, comprising a circular corner point 1, a chiral ligament 2, and an antichiral ligament 3, both of the chiral ligament 2 and the antichiral ligament 3 are tangent to the circular corner point 1 ;

[0033] The antichiral ligament 3 is arranged circumferentially along the vascular stent, and the chiral ligament 2 is arranged axially along the vascular stent to form the first four-ligament chiral antichiral cell 101; the antichiral ligament 3 is arranged along the vascular stent Axially arranged, the chiral ligaments 2 are ...

Abstract

The invention provides a chirality and inverse chirality mixed intravascular stent. The chirality and inverse chirality mixed intravascular stent comprises round angular points, chirality ligaments and inverse chirality ligaments, and the chirality ligaments and the inverse chirality ligaments are all tangent to the round angular points. By means of the chirality and inverse chirality mixed intravascular stent, both the structure of the stent and the endarterium have negative Poisson's ratio features, mechanical properties of the vascular wall can be well matched, the injury in the biologicaltissue of the vascular wall by the stent is reduced, and clinical tissue regeneration is promoted.

Description

technical field [0001] The invention relates to the field of vascular interventional treatment, in particular to a chiral antichiral hybrid vascular stent. Background technique [0002] The number of patients with cardiovascular disease in my country has reached 290 million, and 1 in every 5 adults suffers from cardiovascular disease. About 3.5 million people die of cardiovascular disease every year, 2 out of 5 deaths, and one person dies of cardiovascular disease every 10 seconds, ranking first in the incidence and mortality of all diseases in my country , the situation is grim. With the increasing incidence of cardiovascular and cerebrovascular diseases in recent years, interventional medical engineering has also developed rapidly, and the vascular stent technology as a representative of it has also been favored by clinicians and patients due to its many advantages, thus promoting the development of this technology. [0003] Vascular stents are important medical devices ...
