    摘要: A system (400) comprises a fluid supply (414), a pressure regulator (418), a pressure valve (420), and a vent assembly (422). The fluid supply is fluidly coupled to an outlet tube (416), which is configured to be fluidly coupled to at least a portion of an organ environment (404). The pressure regulator is configured to provide the fluid to an organ (402) in the organ environment via 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. In another system a fluid condenser may be provided, wherein the pressure controller provides a fluid (e.g., ambient air) through a fluid valve and to the fluid condenser, which condenses the fluid (e.g., removing gases such that the supplied fluid is primarily oxygen).

    摘要: An apparatus can include a triply periodic minimal surface. The apparatus can include a 3D scaffold formed from the triply periodic minimal surface. The apparatus can include one or more channels formed by the 3D scaffold. A method of forming a gas exchange unit can include printing a 3D scaffold formed from a triply periodic minimal surface. The 3D scaffold can include a vascular network configured to conduct a fluid. The 3D scaffold can include one or more channels configured to hold a gas. The vascular network can be embedded inside walls of the 3D scaffold. The one or more channels can be positioned between the walls of the 3D scaffold.
