摘要： Claims relate to an organ care system for maintaining an ex vivo lung in a near physiologic functioning condition comprising:
a perfusion circuit for flowing fluid into and out of the ex vivo lung; a composition for use in the perfusion circuit to maintain the ex vivo lung in the near physiologic functioning condition, the composition comprising one or more carbohydrates that include dextran, and a plurality of amino acids that do not include asparagine, glutamine, or cysteine; and
a nutritional subsystem comprising an infusion pump.

摘要： The invention provides a system (1000) for perfusing a lung ex vivo. The system allows for connecting the lung within a fluid perfusion circuit, flowing a perfusion fluid into the lung through a pulmonary artery interface (1022) and away from the lung through a pulmonary vein interface (1026), providing a respiratory gas to the lung for use in metabolism by the lung, the respiratory gas having a pre-determined composition of oxygen, and ventilating the lung through a tracheal interface (1024).

摘要： 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.

摘要： The invention provides, in various embodiments, systems, devices and methods relating to ex-vivo organ care. In certain embodiments, the invention relates to maintaining an organ ex- vivo at near-physiologic conditions. The present application describes a method for using lactate measurement in the arterial and the venous blood lines of the Organ Care System Heart perfusion device to evaluate the: 1) The overall perfusion status of an isolated heart and 2) The metabolic status of an isolated heart and 3) the overall vascular patency of an isolated donor heart. This aspect of the present invention uses 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.
