ABSTRACT:
A pump and valve system having particular use as an artifical heart for human or animal implantation has long-lasting wear characteristics by imparting a relatively slow start ramp to the drive voltage for the pump drive. The ramp reduces the shock to the valves and thus reduces wear. The relatively slow ramp-down of the drive voltage also reduces wear similarly.
