Problems solved by technology

During the implantation of the stent, the vessel wall is mechanically damaged, resulting in the shedding of vascular endothelial cells and the induction of protein adsorption and platelet adhesion and aggregation in the blood, causing inflammation and intimal tissue hyperplasia, leading to in-stent restenosis

Embodiment Construction

[0018] Such as figure 1 and 4 As shown, a novel vascular stent includes: a metal stent 2, on which a rubber adsorption strip 1 is fixed, and the metal stent 2 is made of medical stainless steel or nickel-titanium alloy material, such as image 3 As shown, the adsorption strip 1 is concave in the middle, the thickness of the adsorption strip 1 is 0.02 mm, and the width of the adsorption strip 1 corresponds to the metal bracket 2 . Such as image 3 As shown, the existing vascular stents are easy to cause local vascular injury, cause inflammatory response, intimal hyperplasia and even acute thrombosis, etc., thus leading to the occurrence of clinical acute events.

[0019] Specific method: the vascular stent is compressed and transported to the lesion position, the internal balloon is stretched, the vascular stent is attached to the blood vessel wall 3, the adsorption strip 1 is adsorbed on the blood vessel wall 3, the balloon is deflated, and withdrawn Out of the body, the st...

Abstract

The invention discloses a novel intravascular stent, which comprises a metal bracket and a rubber adsorption strip. The bracket is composed of a wavy ring and a metal material connecting the ribs, andthe rubber adsorption strip is made of a rubber material. A rubber suction cup coats the outer surface of a wire, and the two are connected by a binder. Compared with the existing stent structure, the rubber suction cup of the invention not only can increase the contact area between the stent and the blood vessel wall, reduce the damage to the blood vessel wall, reduce the possibility of restenosis in the stent, and increase the stent in the blood vessel. The adsorption force of the surface prevents the stent from moving. Moreover, the rubber-like material contacts the blood vessel wall surface, so that the novel intravascular stent provided by the invention has the advantages of good biocompatibility and low rejection reaction.

Description

technical field [0001] The invention relates to a novel vascular stent, which is a device for reducing damage to the vascular wall and inhibiting the displacement of the stent in the host blood vessel, and belongs to the technical field of medical device manufacturing. Background technique [0002] With the development of society and the continuous improvement of people's living standards, health has become the most concerned topic in people's daily life. Vascular occlusive diseases caused by atherosclerosis seriously endanger people's health. Nowadays, cardiovascular and cerebrovascular diseases are the number one killer of human health. [0003] At present, the treatment methods for cardiovascular and cerebrovascular diseases caused by vascular stenosis include drug treatment, surgical treatment and stent interventional treatment. Vascular stent interventional therapy has become the first choice for the treatment of occlusive cardiovascular diseases due to its definite c...
