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.

摘要: The disclosure generally relates to a system for perfusing an ex-vivo liver including a pump configured to pump a perfusion fluid through a perfusion circuit, the pump in fluid communication with a hepatic artery interface and a portal vein interface; an oxygenator; a heater; an inferior vena cava interface in fluid communication with an inferior vena cava of the ex-vivo liver; and a reservoir configured to receive the perfusion fluid from the inferior vena cava of the ex-vivo liver and store a volume of fluid.

摘要: The disclosure provides for electrode systems and perfusion systems that may be configured to measure the electrical activity of an explanted heart and to provide defibrillation energy as necessary. The perfusion systems may maintain the heart in a beating state at, or near, normal physiological conditions; circulate oxygenated, nutrient enriched perfusion fluid to the heart at or near physiological temperature, pressure, and/or flow rate. These systems may include a pair of electrodes that may be placed epicardially on the right atrium and/or left ventricle of the explanted heart, and/or an electrode placed in the aortic blood path.

摘要: Electrode systems have been developed for use in perfusion systems to measure the electrical activity of an explanted heart and to provide defibrillation energy as necessary. The perfusion systems maintain the heart in a beating state at, or near, normal physiological conditions; circulating oxygenated, nutrient enriched perfusion fluid to the heart at or near physiological temperature, pressure and flow rate.
