Abstract

In order to develop a new totally implantable artificial herat using vibrating electroagnetic pump (VEMP) which generates flow with the frequency of 1-30 Hz, effects of VEMP drive on hemodynamic parameters were examined. Hemodynamic properties during VEMP drive were evaluated in the frequencys of 5, 10 and 20 Hz using adult goats in 10 acute experiments. This pump acted very well as a left ventricular assist device in any kinds of frequency in the satisfied physiological condition. These results suggest that the VEMP is useful for a totally implantable assist device or a total artificial heart.
