Title: Junying Chen - Innovator in Biodegradable Stents

Introduction

Junying Chen is an inventor based in ChengDu, CN. He has made significant contributions to the field of medical devices, particularly in the development of biodegradable stents. His innovative approach focuses on enhancing the biocompatibility and corrosion resistance of stents, which are crucial for medical applications.

Latest Patent Applications

Junying Chen's notable patent application is for a biodegradable stent. This stent is designed using degradable pure iron or iron alloy, containing 0.01 to 0.5 atom % of elements such as La, Ce, or Sr. The surface of the stent is modified through ion implantation or plasma ion implantation to incorporate oxygen, nitrogen, La, Ce, or Sr. Additionally, the stent can be manufactured by depositing a thin film of these materials onto its surface, with a thickness ranging from 10 to 1000 nanometers and a grain size of 10 to 200 nanometers. This innovative design significantly increases the corrosion resistance of the stents while ensuring good biocompatibility. The degradation process of the stents is controllable, allowing them to provide adequate support in blood vessels for 3-6 months post-intervention before degrading after 6 months.

Conclusion

Junying Chen's work in developing biodegradable stents showcases his commitment to advancing medical technology. His innovative designs have the potential to improve patient outcomes in vascular interventions.
