Title: Gaocan Li: Innovator in Biological Heart Valve Technology

Introduction

Gaocan Li is a prominent inventor based in Chengdu, China, known for his significant contributions to the field of biomedical engineering. He holds 2 patents that focus on innovative solutions for heart valve technology. His work aims to improve the functionality and reliability of biological heart valves, which are crucial for patients requiring heart surgery.

Latest Patents

One of Gaocan Li's latest patents is a "Pre-loadable biological heart valve capable of rapid rehydration and preparation method thereof." This invention involves a method for preparing a biological heart valve that can be rapidly rehydrated. The process includes a cross-linking treatment using an aqueous glutaraldehyde solution, followed by a hydrophilic treatment that immobilizes hydrophilic molecules on the valve through chemical grafting. Finally, a drying treatment is performed to obtain the pre-loadable biological heart valve.

Another notable patent is the "Pre-loadable dried biological heart valve and preparation method thereof." This preparation method consists of soaking a fresh animal pericardium in a solution of soluble elastin or glycosaminoglycan, followed by a first cross-linking reaction. The pericardium undergoes a second cross-linking reaction in an aqueous glutaraldehyde solution before being dried. The resulting dried biological heart valve exhibits excellent toughness and performs well in simulated folding and pressing tests.
