Title: Innovations in Cardiac Valve Replacement by Qun Zhou

Introduction

Qun Zhou is an accomplished inventor based in Lakewood, OH (US), known for his significant contributions to the field of cardiac surgery. With a total of 2 patents, Zhou has developed innovative methods and apparatuses aimed at improving the replacement of diseased cardiac valves. His work has the potential to enhance patient outcomes and streamline surgical procedures.

Latest Patents

Zhou's latest patents include an "Apparatus and method for replacing a diseased cardiac valve." This method involves inserting a delivery catheter into the heart, where a prosthetic apparatus is retained in a compressed state. The apparatus features an annular anchoring member made of Nitinol, which includes a mesh structure defining multiple circumferentially extending rows of cells. A fabric layer is attached to the inner surface of the anchoring member, while an annular support member, also made of Nitinol, is secured within the anchoring member with sutures. The prosthetic valve, made of biological tissue, is then positioned within and secured to the support member. The method allows the prosthetic apparatus to self-expand, ensuring that the anchoring member contacts the tissue of the native atrioventricular valve.

Another patent by Zhou is also titled "Apparatus and method for replacing a diseased cardiac valve." This apparatus is designed to replace a native cardiac valve, which has at least one leaflet and is surrounded by a native cardiac valve annulus. The apparatus comprises a barbell-shaped, expandable anchoring member that includes first, second, and main body portions. The main body portion features a channel defined by inner and outer surfaces, while the first and second end portions are designed to contact the superior and inferior aspects of the native cardiac valve annulus when in an expanded configuration. Additionally, an expandable support member is operably disposed within the main body portion, securing a prosthetic cardiac valve.
