A continuous flow left ventricular assist device (LVAD) that the Penn State University has developed utilizes Tesla turbomachinery technology. Tesla pumping technology patented by Nikola Tesla in the early 20 th century has multiple intriguing characteristics such as simpler manufacturing process, reduced turbulent-related stress, less cavitation due to viscous flow distribution over larger surface areas, and less hemolysis by smooth transition of fluid energy. We successfully tested the 1 st version of the Penn State Tesla LVAD [1, 2]. We recently tested the 2 nd version of the Tesla pump; to make the pump usable in a wide range of patients, the size of the pump was significantly reduced while trying to avoid any degradation of hemodynamic and hemolytic characteristics.
