Although advantages of impeller pump as assist device are well-known,
yet associated problems have limited its application. Based on adva-
nce in solving such problems as hemolysis, bearing and sealing, generation
of pulsatile flow, and development of impeller assist heart, nonpulsatile
as well as pulsatile pump,a prototype design of impeller total heart has
been acomplished.
The device possesses a DC motor with double output shafts, ...
