Title: Eunhee Cho: Innovator in Medical Technology

Introduction

Eunhee Cho is a prominent inventor based in Maplewood, MN (US), known for her contributions to medical technology. With a total of 2 patents, she has made significant advancements in the field of artificial blood vessels and prosthetic heart valves.

Latest Patents

One of her latest patents is the "Thermochromic polyvinyl alcohol based hydrogel artery." This invention involves a method of creating a thermochromic artificial blood vessel by physically cross-linking a polyvinyl alcohol solution in a mold shaped to mimic a blood vessel. The artificial tissue is then chemically cross-linked with a solution that includes a chemical cross-linking reagent. A coagulation solution is applied to the artificial blood vessel to inhibit the chemical cross-linking while promoting physical cross-linking. This innovative vessel can be used to test an ablation catheter, changing color and/or transparency at locations where the temperature increases.

Another notable patent is the "Prosthetic heart valve with expandable microspheres." This prosthetic heart valve features a valve assembly mounted to an expandable stent. The cuff of the valve includes a pocket formed between its outer and inner sides, containing biocompatible and irreversibly expandable microspheres. After implantation, any gaps between the cuff and the native heart valve are exposed to bodily fluid, allowing the blood to enter the pocket and interact with the microspheres. This interaction causes the microspheres to expand, sealing any gaps and preventing leakage.
