Title: Innovations by Roger H. Tu in Natural Tissue Valves

Introduction

Roger H. Tu is a prominent inventor based in Lake Forest, CA (US), known for his significant contributions to the field of bioprosthetics. He holds a total of 8 patents, showcasing his expertise and innovative approach in developing advanced medical devices.

Latest Patents

Among his latest patents, Tu has developed methods for manufacturing natural tissue valves that feature variably compliant leaflets. These innovations include variably compliant natural tissue valve leaflets and vascular bioprosthetics that incorporate these leaflets. The design involves fixing the leaflet base section under greater pressure than the leaflet tip section, resulting in a stiffer base and a more flexible tip. This unique configuration promotes even distribution of mechanical stress on the valve assembly during the cardiac cycle, leading to improved hemodynamic performance while also retarding the calcification of the leaflet tissue.
