What Are the Different Types of Endovascular Stent?

Intravascular stents are used to effectively treat cardio-cerebral vascular diseases such as coronary heart disease. Intravascular stents are used to support narrow or even blocked coronary arteries to ensure smooth blood flow.

Endovascular stent for effective treatment

At present, the number of intravascular stent applications in the United States exceeds 1 million per year, and there is considerable room for growth in the application of intravascular stent in China. The current application is about 40,000 per year, with an annual growth rate of more than 50% in the past three years. The price of the internal stent is more than 3-4 million yuan / piece, which is a heavy burden for our patients. At present, the major problems in the application of intravascular stent at home and abroad are the restenosis of the intravascular stent implantation, insufficient anticoagulation, the harmful metal ions of stainless steel such as nickel and chromium release, which may lead to tissue proliferation.

Only two US companies have reduced restenosis through drug-coating technology. With the support of the national "973" major project, we have developed a vascular stent that can overcome the above problems, and animal tests have obtained good results. It has advanced properties that can simultaneously suppress tissue proliferation and excellent blood compatibility, and can inhibit the release of harmful ions.
