Title: Frank Pk Hsu and a Calcium-Activated Liquid Embolic Material.

Introduction

Frank Pk Hsu is an inventor based in Irvine, California, whose work includes a patent for a liquid embolic material composition. The invention addresses the delivery and stability of embolic materials used in neurovascular interventions.

Latest Patents

Hsu’s patent, “Liquid embolic material composition,” describes an injectable composition made from natural polymers, water, and angiographic contrast agents. Its single-component material is activated by calcium ions in blood, triggering coagulation. The design aims to improve mechanical stability, reduce fragmentation in the target vessel, and maintain durability after deployment. Contrast compounds also support visualization under fluoroscopy.

The patent describes aqueous solutions that allow gellan gum concentrations above 0.5 wt% to remain in a liquid state at temperatures of 30–40°C. This approach is intended to preserve injectability while improving the material’s mechanical stability after delivery. Hsu is credited with 1 patent in the information provided.
