Arsenic trioxide drug stent is a degradable stent with arsenic trioxide drug coating. As an original product of China, the drug eluting stent and drug delivery system project has obtained 8 invention patents (utility models) from China, the United States, the European Union and Japan. It is the only drug stent product with independent intellectual property rights in China. The drug stent delivery system has been completed, and has passed the clinical observation and follow-up of hundreds of cases for 3-5 years, with no adverse reactions and good performance. [ 1]
principle
Arsenic trioxide drug stent has good endothelial control in the short term and can achieve long-term intimal repair function. Making full use of the medicinal properties of arsenic trioxide can effectively put endothelial cells into a dormant state, thus preventing vascular restenosis and avoiding the problem of endothelial proliferation in the acute stage.
The drug coating is degradable, which is beneficial to the long-term repair of vascular endothelium and avoids the pain of traditional drug stents taking drugs for life. The drug coating is released step by step according to a certain time, and the drug loading is only 2.95ug/mm, which has a very good dual effect on the control and repair of vascular endothelium.
The original' arsenic trioxide drug-coated biodegradable stent' has good endothelial control in the near future and can achieve long-term intimal repair function.
