  • Publication number: 20240397937
    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. The present application describes, for example, a method for using lactate measurement in the arterial and the venous blood lines of the Organ Care System Heart perfusion device to evaluate, for example, the: 1) overall perfusion status of an isolated heart; 2) metabolic status of an isolated heart; and 3) overall vascular patency of an isolated donor heart. 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.

  • Publication number: 20230413805
    Abstract: The disclosure, in various embodiments, provides systems, methods, and solutions for perfusing an organ. The present application describes illustrative methods for perfusing an ex-vivo organ in a functioning state under physiological or near physiological conditions, including receiving an ex-vivo organ in an organ care system, the ex-vivo organ coupled to a perfusion circuit, infusing a solution into the system, combining the solution with a perfusion fluid to create a mixed solution, pumping the mixed solution to the ex-vivo organ, and receiving the mixed solution from the ex-vivo organ.
