N2 - An electromagnetically driven univalved artificial heart (AH) has been develping to obtain a totally implantable Ventricular Assist Device (VAD) including drive system, using vibrating method in the frequency range of 3-50 Hz. This newly designed VAD consists of a vibrating tube, coils, magnets and a jelly fish valve as the outlet valve. This VAD could generate more than 10 l/min as an output volume, with 10 Hz vibration using 20 volts supplied elective voltage. The flow patterns show vibrating flow according to drive frequencies. The fluid mechanical, hemodynamic and hematologic properties using a mock circulation and adult goats showed following advantages toward the achievement of a totally implantable VAD including a powering system. 1. Unidirectional flow through the univalved pump in the high frequency pump generation. 2. Simple drive mechanism. 3. A wide variety of output volume between 0.51/-101/min. 4. High efficiency transcutaneous electric power transmission.
