Abstract: A system comprises a fluid supply, a pressure regulator, a pressure valve, and a vent assembly. The fluid supply stores a volume of a fluid and is fluidly coupled to an outlet tube. The outlet tube is configured to be fluidly coupled to at least a portion of an organ environment. The organ environment configured to hold an organ. The pressure regulator is fluidly coupled to the outlet tube and is configured to maintain a fluid pressure of the fluid being supplied to the organ environment from the outlet tube. The fluid being supplied is at a pressure range above ambient to maintain the organ in an inflated position. The pressure valve is fluidly coupled to the outlet tube and inhibits increase of the fluid pressure above a threshold. The vent assembly removes excess fluid from the organ environment and includes a vent tube disposed within the organ environment and a vent valve disposed outside of the organ environment.
