Abstract

The invention discloses a kind of novel vascular stents, it includes: metallic support and rubber suction item.Bracket is made of the metal material of wave ring and dowel, and rubber suction item uses rubber type of material.Rubber suction cups overlays on wire outer surface, is that the two is connected by binder.Compared with existing supporting structure, rubber suction cups of the invention can not only increase the contact area of bracket and vascular wall, reduce the injury to vascular wall, reduce a possibility that in-stent restenosis occurs, and the adsorption capacity on bracket surface in the blood vessels can be increased, prevent bracket from moving.Moreover, rubber material contacts blood vessel wall surface makes the present invention also have good biocompatibility, the low advantage of rejection.

Description

A kind of novel vascular stent
Technical field
The present invention relates to a kind of novel vascular stent, it is a kind of for reducing to vascular damaged, inhibits bracket in host The intravascular device being subjected to displacement, belongs to manufacture technology field of medical appliance.
Background technique
With the development and continuous improvement of people's living standards of society, health becomes in people's daily life to be paid close attention to the most Topic.The angiemphraxis disease due to caused by atherosclerosis seriously endangers people's health.Nowadays cardiovascular and cerebrovascular disease It has been the first killer for endangering human health.
There are drug therapy, surgical operation therapy for the treatment method of the cardiovascular and cerebrovascular disease as caused by hemadostewnosis at present With bracket interventional therapy.Intravascular stent interventional therapy is because of curative for effect, operation wound is small, rehabilitation duration is short and expense is relatively low The features such as honest and clean, has become the prefered method for the treatment of occlusion type cardiovascular disease, but is still faced with severe postoperative clinic and asks Topic, such as in-stent restenosis and acute thrombus.
It is one of the basic reason for inducing in-stent restenosis to the localized vascular injury of host blood vessel wall after stenter to implant. Vascular wall is made mechanical damage occur in stent implantation procedure, so that vascular endothelial cell be caused to fall off and induce albumen in blood Matter absorption and platelet adhesion reaction and aggregation, cause inflammatory reaction and neointimal tissue proliferation, lead to the generation of in-stent restenosis.Such as What is still the major issue that cardiovascular Jie's implantation instrument faces to the damage of vascular wall bring after reducing stenter to implant.
Summary of the invention
The present invention provides a kind of novel aiming at the problem that post stent implantation restenosis and the technological deficiency of existing intravascular stent Intravascular stent, comprising: metallic support is fixed with adsorption bar on the metallic support.
Preferably, the metallic support is medical stainless steel or nickel-titanium alloy material.
Further, the adsorption bar surface is rubber material.Using rubber material, reduce the injury to vascular wall, Adsorption capacity is also enhanced simultaneously.
Preferably, the adsorption bar is bonded on the metallic support by biogum.
Further, the adsorption bar with a thickness of 0.02mm, the adsorption bar width and the metallic support are corresponding.
Preferably, being in umbilicate type among the adsorption bar.
The utility model has the advantages that the present invention can not only increase the contact area of bracket and vascular wall, reduce the injury to vascular wall, A possibility that in-stent restenosis occurs is reduced, and the adsorption capacity on bracket surface in the blood vessels can be increased, prevents bracket from sending out Raw movement.Moreover, the present invention has good biocompatibility, the low advantage of rejection.

Specific embodiment
As shown in figs. 1 and 4, a kind of novel vascular stent, comprising: metallic support 2 is fixed on the metallic support 2 Rubber suction item 1, the metallic support 2 are medical stainless steel or nickel-titanium alloy material, as shown in figure 3, during the adsorption bar 1 is Between umbilicate type, the adsorption bar 1 with a thickness of 0.02mm, 1 width of adsorption bar and the metallic support 2 are corresponding.Such as Fig. 3 Shown, existing intravascular stent easily leads to localized vascular injury, causes inflammatory reaction, endometrial hyperplasia even acute thrombus etc., thus Lead to the generation of clinical acute event.
Concrete mode: transporting lesion locations after the intravascular stent bracket compression, inner balloon effect struts, the blood Pipe holder sticks vascular wall 3, and the adsorption bar 1 is adsorbed on vascular wall 3, Deflation, withdraws from vitro, bracket stays, and adopts The contact area of bracket Yu vascular wall 3 can not only be increased with the adsorption bar 1, reduce the injury to vascular wall 3, reduce bracket A possibility that interior restenosis occurs, and the adsorption capacity on bracket surface in the blood vessels can be increased, prevent bracket from moving.
