Abstract: In a method of ventilating excised lungs, a ventilation gas is supplied to an airway of a lung and a vacuum is formed around the lung. A quality of the vacuum is varied between a lower level and a higher level to cause the lung to breathe, while the pressure of the ventilation gas supplied to the airway is regulated to maintain a positive airway pressure in the airway of the lung. The vacuum may be cyclically varied between the two vacuum levels. The levels may be maintained substantially constant over a period of time, or one or both of the lower and higher levels may be adjusted during ventilation. The lung may be placed in a sealed chamber, and a vacuum is formed in the chamber around the lung.

Abstract: The disclosure provides, in various embodiments, systems, devices and methods relating to ex-vivo organ care. In certain embodiments, the disclosure relates to maintaining an organ ex-vivo at near-physiologic conditions.

This aspect of the present disclosure may use, for example, the property of myocardial cell's unique ability to produce/generate lactate when they are starved for oxygen and metabolize/utilize lactate for energy production when they are well perfused with oxygen.

Abstract: Apparatus for perfusion of multiple types of organs include base unit configured to removably couple with a perfusion module for perfusing an organ. The base unit has conduits for connecting a source of a perfusate to the organ to circulate the perfusate through the organ; first and second pumps coupled to the conduits for driving circulation of the perfusate in the conduits; and a controller configured and connected for controlling the first and second pumps to regulate the circulation of the perfusate through the organ. The controller is operable to control the first and second pumps to perfuse the organ in accordance with organ specific perfusion parameters. The organ specific perfusions parameters are selected based on the type of the organ, and may be selected by an operator for at least two organ types selected from the group of heart, liver, kidney and lung.

Abstract: Methods and systems of maintaining, evaluating, and providing therapy to a lung ex vivo. The methods and systems involve positioning the lung in an ex vivo perfusion circuit; circulating a perfusion fluid through the lung, the fluid entering the lung through a pulmonary artery interface and leaving the lung through a left atrial interface; and ventilating the lung by flowing a ventilation gas through a tracheal interface. Maintaining the lung for extended periods involves causing the lung to rebreath a captive volume of air, and reaching an equilibrium state between the perfusion fluid and the ventilation gas. Evaluating the gas exchange capability of the lung involves deoxygenating the perfusion fluid and measuring a time taken to reoxygenate the perfusion fluid by ventilating the lung with an oxygenation gas.
