An embodiment of the present invention includes a tray and a method for loading a medical device on a catheter assembly. The tray can include a tray body defining a first receptacle for seating the handle assembly of the catheter assembly, an elongate receptacle for seating a delivery shaft of the catheter assembly, and a reservoir for holding a fluid. A portion of the elongate receptacle slopes downward towards the reservoir. The reservoir has a bottom surface that is below a portion of the elongate receptacle that is contiguous with the reservoir. Accordingly, when the reservoir is filled with a fluid and the catheter assembly is seated in the first receptacle and the elongate receptacle, the distal tip of the catheter assembly is submerged in the fluid in the reservoir. The tray body is also configured to prevent movement of a catheter assembly seated therein.
