Organ transporter with oxygen generation

An apparatus for perfusing an organ or tissue, the apparatus comprising:

• a perfusion circuit (i) comprising a plurality of flow paths by which liquid perfusate may flow to the organ or tissue and (ii) configured to perfuse the organ or tissue with the liquid perfusate so that perfusate flow in the plurality of flow paths is self-regulated by the organ or tissue;
• either:
• (i) an oxygenator, which is connected to the perfusion circuit and is configured to supply oxygen to each of the perfusate flow paths, and at least one on/off valve or pressure regulator, which is configured to control an amount of oxygen supplied to each of the perfusate flow paths to be different;
• or
• (ii) a plurality of oxygenators connected to the perfusion circuit and configured to supply oxygen to each of the perfusate flow paths, a separate one of the plurality of oxygenators being provided for each of the plurality of flow paths;
• an oxygen supply device that is external to and separable from the remainder of the apparatus and that is configured to supply produced oxygen to the oxygenator or the plurality of oxygenators;
• and
• an accumulator configured to reduce pulsatility of the perfusate flow in the plurality of flow paths,
• wherein (i) the oxygenator and the at least one on/off valve or pressure regulator or (ii) the plurality of oxygenators are configured to supply oxygen to each of the perfusate flow paths such that (a) the amount of oxygen supplied to each of the perfusate flow paths is separately controllable and (b) the liquid perfusate in a first flow path of the perfusate flow paths has a different level of oxygenation than the liquid perfusate in a second flow path of the perfusate flow paths, and
• wherein the oxygenator or the plurality of oxygenators is configured to oxygenate the perfusate as the oxygen is produced.
