Abstract
A method for controlling a pump for delivery of liquid to an organ over a series of fixed-length time intervals f, each interval f comprising a time tand a time twherein t+tequals the length of interval f. The method comprises allowing output pressure of the pump to decrease over time t, increasing output pressure of the pump over time t, comparing achieved pump output pressure to a predetermined pressure at about the end of interval f, and at least one of (i) adjusting tand tif necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f, and (ii) adjusting a rate of change of the output pressure during at least one of tand tif necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f.
