Abstract

A device for programming an implantable fluid delivery device receives a therapeutic agent concentration, wherein the therapeutic agent concentration comprises a mass of the therapeutic agent per unit of volume. The device further determines a reference rate value based on the received therapeutic agent concentration, wherein the reference rate value comprises a mass per unit of time. The device additionally displays a graphical user interface comprising a horizontal axis and a vertical axis, wherein the horizontal axis represents time and the vertical axis represents rates of delivery of the fluid by the implantable fluid delivery device. The maximum value of the vertical axis displayed in the graphical user interface is determined based on the determined reference rate value and is determined to be less than a maximum therapeutic agent infusion rate.
