Abstract

The invention discloses an arterial stent which comprises a stent body and a covering film, the covering film covers the stent body to form the film, the stent body comprises a cylindrical stent and a fixed stent, and the end of the cylindrical stent is connected with the fixed stent. Meanwhile, each circle of fixing support is bent oppositely and reversely, the connecting face of the blood vessel and the fixing support is bent through the elasticity of the blood vessel, the connecting area between the blood vessel and the support is increased, and gaps are reduced; therefore, the problem that blood vessels are slowly healed due to the fact that a gap between the covered stent and the blood vessels is difficult to seal under the impact of blood flow and the blood flow continues to impact the middle membrane and the outer membrane is solved.

Description

technical field [0001] The invention relates to the technical field of arterial stents, in particular to an arterial stent. Background technique [0002] Normal human arterial blood vessels are composed of three layers, intima, media and adventitia. The three layers closely fit together and jointly carry blood flow. Arterial dissection refers to the local tear of the intima, which is affected by strong blood flow. Impact, the intima gradually peels off and expands, forming two true and false lumens in the artery. This results in a series of manifestations including tear-like pain. The aorta is the main blood vessel of the body. It bears the pressure directly from the beating of the heart. The blood flow is huge and the intimal layer is torn. Without proper and timely treatment, the chance of rupture is very high, and the mortality rate is also very high. According to the location of the rupture and the location of the artery, dissection can involve all parts of the body. T...
