Systems and methods for an ex vivo tissue perfusion apparatus are provided. In certain embodiments, the disclosed subject matter includes a container to store ex vivo tissue, a plurality of tubes containing a perfusate, and a pump which cycles the perfusate through the ex vivo tissue. The perfusion apparatus can be configured for mobility and can be transported to active emergency situations in order to perform mobile perfusion of ex vivo tissues. In certain embodiments, the discloses subject matter contemplates a method for performing mobile profusion of ex vivo tissue in emergency situations, for example, active warzones. In certain embodiments, the profusion apparatus can be used as part of a method of training for doctors in the reattachment of limbs or other extremities that have been amputated.

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. In certain embodiments, the disclosure relates to testing properties of an ex-vivo heart or an organ care system, adjusting a property of the organ care system in response to certain results of the testing, and re-testing the ex-vivo heart or the organ care system. In certain embodiments, the disclosure relates to synchronizing at least one cycle of a pumping of a perfusion fluid with a state of the ex-vivo heart.

Zebrafish are a powerful model for investigating cardiac repair due to their unique regenerative abilities, scalability, and compatibility with many genetic tools. However, characterizing the regeneration process in live adult zebrafish hearts has proved challenging because adult fish are opaque and explanted hearts in conventional culture conditions experience rapid declines in morphology and physiology. To overcome these limitations, we fabricated a fluidic device for culturing explanted adult zebrafish hearts with constant media perfusion that is also compatible with live imaging. Unlike hearts cultured in dishes for one week, the morphology and calcium activity of hearts cultured in the device for one week were largely similar to freshly explanted hearts. We also cultured injured hearts in the device and used live imaging techniques to continuously record the revascularization process over several days, demonstrating how our device enables unprecedented visual access to the multi-day process of adult zebrafish heart regeneration.

The present application describes a pollinator species detection and monitoring device and system that utilizes specifically positioned and spaced receptacles for determining and conveying the numbers, health and movements of pollinator species ranging from real-time to intermittent transmittance of detected information for an area, region, areas or regions, singularly and in the aggregate. The detected information is collected and recorded via a pair of closely related sensors, residing at 180 degrees from one another, wherein pollinator species' entrance, exit, number, gender and activity are sensed, analyzed algorithmically and stored locally for eventual transmittance from a transmitting device to an external computer or mobile device for data observance, collection, storage and analysis. Detected information may be species specific or across a plurality of species.

The present invention relates to a colloidal solution free of human or animal blood derivatives for the ex-vivo perfusion, regeneration and storage of the lungs before transplantation.

An apparatus for perfusing an organ or tissue includes a perfusion circuit for perfusing the organ or tissue; an oxygenator for oxygenating perfusate that circulates through the perfusion circuit; and an oxygen supply device such as an oxygen concentrator or an oxygen generator configured to supply oxygen to the oxygenator. A method of perfusing an organ or tissue includes producing oxygen from a device such as an oxygen concentrator and an oxygen generator; supplying the produced oxygen, preferably as the oxygen is produced, to a perfusate to oxygenate the perfusate; and perfusing the organ or tissue with the oxygenated perfusate. The produced oxygen preferably has a concentration greater than the oxygen concentration in air.

An organ preservation system includes an organ container, an organ holder, a liquid supply tube, a drainage tube, and a pressure regulator. The organ container has a closed organ preservation space. The organ holder holds an organ in the organ preservation space. The liquid supply tube supplies a liquid to the organ. The drainage tube drains the liquid from the organ. The pressure regulator regulates air pressure in the organ preservation space. The organ container includes first to third connectors providing communication between the organ preservation space and an exterior space. The first, second, and third connectors are detachably connected to a liquid supply tube, a drainage tube, and a suction tube, respectively. When the organ is preserved ex vivo while being perfused with the liquid, the organ can be connected with ease to the tubes, and this ensures hermetical sealing of the space where the organ is preserved.

The invention provides a system for normothermic, ex vivo restoration and preservation of an intact mammalian brain, and other organs. In certain aspects, the system is capable of preserving a brain as well as other organs, maintaining cellular integrity and cellular function for hours post mortem or after global ischemia. The invention also provides synthetic brain perfusate formulations, including a novel brain perfusion medium (BPM), which are able to reduce reperfusion injury, stimulate recovery from hypoxia, prevent edema and metabolically support the energy needs of brain function.

A system for the hypothermic transport of biological samples, such as tissues, organs, or body fluids. The system includes a self-purging preservation apparatus to suspend a sample in preservation fluid and perfuse a tissue with preservation fluid. The self-purging preservation apparatus is placed in an insulated transport container having a cooling medium. When assembled, the system allows for transport of biological samples for extended periods of time at a stable temperature.

Oxygenation constituents and finished oxygenation media, as well as methods of making oxygenation constituents and finished oxygenation media are provided. The oxygenation constituents comprise a hemoglobin preparation, and a red blood cell preparation. The oxygenation constituents comprise from about 10% to about 99% by weight hemoglobin of the hemoglobin preparation and the balance by weight hemoglobin of the oxygenation constituents comprise a red blood cell preparation. The finished oxygenation media comprise the oxygenation constituents and one or more other ingredients such as a diluent, or excipient. The finished oxygenation media can be used to ex-vivo preserve organs or tissue.
