Title: Sung Yun Hann and Biomimetic Blood Vessel Engineering.

Introduction

Sung Yun Hann is an inventor associated with The George Washington University in Arlington, Virginia. His work includes a patent describing a method for producing artificial blood vessels with flexible, multilayer structures inspired by natural blood vessels.

Latest Patents

Hann is associated with 1 patent: “3D Printing of Biomimetic Flexible Multilayer Blood Vessels — Systems and Methods for Producing Artificial Blood Vessels.” The disclosed method includes printing an elastic outer layer and removing its polyvinyl alcohol component. It then forms a first inner layer from smooth muscle cells mixed with fibrinogen solution and extruded with thrombin to create a cell gel. A second inner layer is formed similarly from endothelial cells, fibrinogen solution, and thrombin. Together, these steps describe a layered approach to fabricating artificial blood vessels.

Career Highlights

Hann’s patent work focuses on applying 3D printing and cell-based materials to the production of biomimetic blood vessels. The described process combines an elastic outer layer with distinct inner layers of smooth muscle and endothelial cells.
