Title: Innovations by Dongyun Hao in Vascular Stent Technology

Introduction

Dongyun Hao is a prominent inventor based in Beijing, China, known for his significant contributions to the field of biomedical engineering. He holds 2 patents that focus on advanced vascular stent technologies, which aim to improve patient outcomes in cardiovascular treatments.

Latest Patents

His latest patents include a cobalt-chromium alloy stent and a drug-eluting stent. The cobalt-chromium alloy stent comprises several main body units, each made up of supporting rings connected by flexible ribs. The adjacent main body units are linked by connecting ribs. This innovative design enhances the stent's performance in vascular applications. The drug-eluting stent incorporates a drug coating containing arsenic trioxide and tacrolimus. The drug release curves of these composite drugs are adjusted to effectively inhibit the inflammatory response of vascular endothelial cells and the proliferation behavior of vascular smooth muscle cells, thereby reducing the vascular restenosis rate.

Another notable patent is the degradable biomedical magnesium alloy drug-eluting vascular stent and its preparation method. This stent is designed with a magnesium alloy that includes specific components such as Gd, Y, Li, Zn, and Zr, ensuring good radial support strength and strain dispersion capability. The use of a protective coating significantly improves the corrosion resistance of the magnesium alloy stent. Additionally, an arsenic trioxide/rapamycin and tacrolimus composite drug sustained-release system is employed to adapt to the damage repair process of blood vessels. The implantation results in large animals demonstrate that this vascular stent system has a favorable anti-restenosis treatment effect.
