Priming tray for priming a fluid system

A method for priming a cardiac assist system, the method comprising:

• connecting tubing of a first component of the cardiac assist system to an inlet port of a priming tray;
• connecting tubing of a second component of the cardiac assist system to an outlet port of the priming tray;
• the priming tray comprising:
• a body having a base wall and a plurality of side walls upstanding from the base wall to define an interior reservoir configured for holding a volume of fluid, the base wall defining a first planar base surface and a second planar base surface extending on an obtuse angle from the first planar base surface;
• filling the interior reservoir with the fluid while the priming tray is in a first position in which the body is supported on the first planar base surface;
• tilting the priming tray from the first position to a second position where the body is tilted to rest on the second planar base surface;
• wherein when the body is tilted from the first position to the second position, the fluid flows through the tubing of the first component and the tubing of the second component to prime the cardiac assist system with the fluid from the priming tray via gravity.
