Introduction

Richard L. Li is an inventor associated with Holmdel, New Jersey, and Columbia University. His patent work addresses a transcatheter valve prosthesis designed to expand within the body.

Latest Patents

The provided information lists one patent for Li: “Transcatheter Dilatable Biostable Polymeric Stented Valved Tube Prosthesis.” The invention describes a tubular member that can be plastically deformed from one dimension to another, alongside a valve component with expandable leaflets. Elastomeric glue secures the valve component to the tube at two circumferential regions, creating an annular cavity. An expandable stent sits within that cavity between the valve component and the tubular member. The design aims to support a dilatable valve prosthesis for transcatheter use.
