Abstract
The utility model discloses a novel coronary artery intravascular stent. The novel coronary artery intravascular stent of a cylindrical structure is formed by welding a plurality of hexagon single structures in a combination mode, and laser technology is used for polishing after welding. Each corner of the hexagon single structures is a round corner. The novel coronary artery intravascular stent is made of titanium alloy or stainless steel or magnesium alloy. Compared with a traditional coronary artery intravascular stent, the novel coronary artery intravascular stent has the advantages that the shape is reduced, toughness is improved, a space area of an inner supporting bar is increased, radial support force is strengthened, and meanwhile, the novel coronary artery intravascular stent can enter lateral branches easily. With the advantages, after the novel coronary artery intravascular stent is used in an angioplasty, intimal hyperplasia resisting agents of sufficient amount can be applied and stored effectively on an artery wall, and reagents can be transported to the inner layer of the artery wall close to a damaged portion provided with the stent effectively at the same time.
Description
Technical field
This utility model relates to a kind of medical instruments field that is used for the treatment of coronary heart disease, particularly a kind of Novel coronary artery intravascular stent.
Background technology
Coronary heart disease is called for short coronary heart disease.Refer to that because lipid metabolism is undesired lipid calmness in the blood is piled up at the lipid material of some similar medicated porridge samples of endarterium and to be formed white speckle, is called atherosclerotic lesion on the endarterium of otherwise smooth.These specklees gradually increase and cause lumen of artery narrow, and blood flow is obstructed, and cause heart ischemia, produce angina pectoris.Its Therapeutic Method is mainly Coronary Artery Bypass and stenting:
Bypass operation of coronary artery is to get one section blood vessel from other positions of patient self, then it is connected on respectively two ends coronarius narrow or that stopped up, blood flow can be taken a devious route by " bridge ", thereby make the cardiac muscle of ischemia obtain the oxygen confession, and the symptom of alleviate myocardial ischemia.
Percutaneous coronary intervention (pci) (PCI), it is stenting, interventional therapy is not surgical operation and a kind of cardiac catheter technology, specifically be by the femoral artery of thigh root or the radial artery on the wrist, through vascular puncture support or other apparatus are put into the coronary artery the inside, reach the purpose of removing coronary stricture.The wound of interventional therapy is little, definite effect, risk little (<1%).The restenosis rate of common metal bare bracket is 15%-30%.The application of coating stent of medicine has further improved the long-term efficacy of stenting, population restenosis rate 3%, and diabetes/complex lesions is about 10%, and its effect can compare favourably with coronary artery bypass surgery.
The intracoronary stent iatrotechnics is emerging in recent years a kind for the treatment of technology, namely the stainless steel metal support is sent into the Coronary Artery Lesions position and be retained in the there through peripheral blood vessel, expands narrow arteria coronaria and reaches therapeutic purposes to increase blood flow.
In recent years clinical research shows, support the concurrent tunica intima interlayer of coronary angioplasty, serious endarterium tear or the acute occlusion situation under, can keep vascular patency, thereby avoid the acute coronary Coronary Artery Bypass, and reduce myocardial infarction and occur.The someone thinks that the support implantation can prevent or alleviate the coronary restenosis of percutaneous tranluminal coronary angioplasty postoperative simultaneously.
The utility model content
For above-mentioned technical problem, this utility model provides a kind of Novel coronary artery intravascular stent, and this support can be placed in the coronary artery, treats the diseases such as the angina pectoris that causes because of coronary artery pathological changes or myocardial infarction.
The technical scheme that its technical problem that solves this utility model adopts is that this Novel coronary artery intravascular stent is cylindrical structure, is combined by a plurality of hexagon monomer structure welding, polishes with laser technology after the welding; Each angle of described hexagon monomer structure is fillet, and described Novel coronary artery intravascular stent is made by titanium alloy, rustless steel or magnesium alloy.
The beneficial effect that this utility model produces is, this Novel coronary artery intravascular stent is different from traditional support, its profile reduces, pliability increases, be easier to enter side shoot, the inner supporting rod spatial area increases, and radial support power strengthens, thereby in the anti-neointimal hyperplasia agent of adopting this support can effectively use and preserve sufficient amount after carrying out angioplasty on arterial wall, the while can be transported to reagent near the damaged part with this support the arterial wall internal layer effectively.
Description of drawings
Be elaborated below in conjunction with the drawings and specific embodiments:
As shown be structure chart of the present utility model
Among the figure, 1, hexagon monomer structure 2, fillet
The specific embodiment
As shown in the figure, this utility model is a kind of Novel coronary artery intravascular stent, is cylindrical structure, is combined by a plurality of hexagon monomer structure 1 welding, polishes with laser technology after the welding; Each angle of described hexagon monomer structure 1 is fillet 2, and described Novel coronary artery intravascular stent is made by titanium alloy, rustless steel or magnesium alloy.
This Novel coronary artery intravascular stent can be adjusted according to actual needs and make length and thickness, is applicable to the treatment of different coronary artery diseases.
This utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
The technology that this utility model is not described in detail, shape, structure partly are known technology.
