Shanghai Jiaotong University develops a degradable magnesium alloy that is expected to be a cardiovascular stent

Recently, the Biomaterials Research Group of the National Engineering Research Center for Light Alloy Precision Forming at Shanghai Jiaotong University has developed a new magnesium alloy material that can be completely degraded in animals, and is expected to be used to manufacture a new generation of cardiovascular stents. The research team cooperated with the research group of Professor Rong Fan of the Department of Biomedical Engineering at Yale University to publish the research results in the internationally renowned academic journal "Nanoscale". The international core journal "Chemical World" also used "Next-generation cardiovascular stents" Comment on this topic.

It is reported that the new alloy combines the long-term functionality and the final complete degradation of the service within a certain period of time, and will be an ideal material for temporary implantation of medical devices in the body. The cardiovascular stent made of this material can be used to treat atherosclerosis and other heart diseases Vascular diseases. The National Engineering Research Center for Light Alloy Precision Forming is led by Professor Ding Wenjiang. He has devoted himself to the research of degradable medical magnesium alloy materials for many years, both in the controllable degradation of magnesium alloy materials for cardiovascular stents and high-strength medical magnesium alloy materials for bone repair. A breakthrough has been made, and the medical magnesium alloy JDBM (JiaoDa BioMg) series with independent intellectual property rights has been developed, and all of them have entered the stage of large animal testing. "In the next 3-5 years, this degradable medical magnesium alloy material, known as 'revolutionary metal biomaterial', is expected to be used clinically to benefit the majority of sick patients." Professor Yuan Guangyin, who is responsible for research in this direction, is full of this confidence.
