King Saud University has received a US patent for a mechanical heart valve developed by cardiac-sciences professor Dr. Rakan bin Ibrahim Nazer, according to an Arab News report published on 9 October.
Three coordinated leaflets

The invention focuses on leaflet motion and flow dynamics compared with conventional mechanical valve designs.
