A programmer device includes an interface that communicates with an implantable fluid delivery device and a user interface that displays a representation of a portion of the implantable fluid delivery device and displays an indication of a location of fluid within the implantable fluid delivery device during a delivery phase, e.g., a priming or bridging phase. The user interface may display a representation of progress of the delivery phase. The user interface may display the indication of the location of the fluid within internal tubing of the implantable fluid delivery device or within a catheter of the implantable fluid delivery device. The programmer device may display the representation of the progress of the delivery phase as a simulation of the delivery phase or during the actual delivery phase of the implantable fluid delivery device. A user may therefore observe a location of fluid corresponding to progress of the delivery phase.
