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.

Disclosed are apparatuses and methods for irradiating a perfusate. The apparatus includes a tank which defines a first chamber. A separator is located inside the first chamber. The separator defines a second chamber. The first chamber and the second chamber are concentric and have substantially annular cross sections, each having at least one diameter and a substantially common longitudinal axis. A perfusate is introduced into the first chamber by an inlet. A UV radiation-emitting device is disposed inside the second chamber for providing irradiation to the perfusate. Irradiated perfusate is removed from the tank by an outlet. Other apparatuses and systems are described and methods for inactivating micro organisms by performing EVP and irradiating the perfusate.

An apparatus, a system, and methods for receiving, perfusing and maintaining and assessing excised donor heart physiological functionality. The system generally comprises an apparatus for receiving and holding an excised heart that is interconnected with: (i) a perfusate-processing system, (ii) a bi-directional perfusate pumping system, (iii) flow sensors for monitoring the flow of perfusate to and from an installed heart's aorta, pulmonary artery, pulmonary vein, and vena cava, (iv) an ECG apparatus interconnectable with the installed heart, and (v) probes interconnecting the installed heart with instruments for monitoring the heart's physiogical functionality using load independent indices and load dependent indices.

Apparatus and methods for providing extracorporeal blood circulation and oxygenation control include multi-stage de-airing of blood to provide automated cardiopulmonary replacement to preserve the viability or one or more organs in a clinically dead organ donor or harvested donor organ for subsequent transplantation to an organ receiver patient.

Compositions, methods, systems/devices and media are provided for maintaining a harvested organ in a functioning and viable state prior to implantation. The organ perfusion apparatus includes a preservation chamber for storing the organ during the preservation period. A perfusion circuit is provided having a first line for providing an oxygenated fluid to the organ, and a second line for carrying depleted fluid away from the organ. The perfusion apparatus also includes a device operably associated with the perfusion circuit for maintaining the organ at a substantially normothermic temperature.

Described are systems and methods for monitoring administration of nitric oxide (NO) to ex vivo fluids. Examples of such fluids include blood in extracorporeal membrane oxygenation (ECMO) circuits or perfusion fluids used for preserving ex vivo organs prior to transplanting in a recipient. The systems and methods described herein provide for administering nitric oxide to the fluid, monitoring nitric oxide or a nitric oxide marker in the fluid, and adjusting the nitric oxide administration.
