Drop-to-drop connection schemes are described for putting a microfluidic device in fluidic communication with a fluid source or another microfluidic device, including but not limited to, putting a microfluidic device in fluidic communication with the perfusion manifold assembly.

A perfusion manifold assembly is described that allows for perfusion of a microfluidic device, such as an organ on a chip microfluidic device comprising cells that mimic cells in an organ in the body, that is detachably linked with said assembly so that fluid enters ports of the microfluidic device from a fluid reservoir, optionally without tubing, at a controllable flow rate.

A culture module is contemplated that allows the perfusion and optionally mechanical actuation of one or more microfluidic devices, such as organ-on-a-chip microfluidic devices comprising cells that mimic at least one function of an organ in the body.

A culture module is contemplated that allows the perfusion and optionally mechanical actuation of one or more microfluidic devices, such as organ-on-a-chip microfluidic devices comprising cells that mimic at least one function of an organ in the body. A method for pressure control is contemplated to allow the control of flow rate (while perfusing cells) despite limitations of common pressure regulators. The method for pressure control allows for perfusion of a microfluidic device, such as an organ on a chip microfluidic device comprising cells that mimic cells in an organ in the body, that is detachably linked with said assembly, so that fluid enters ports of the microfluidic device from a fluid reservoir, optionally without tubing, at a controllable flow rate.

Systems and methods of the invention generally relate to prolonging viability of bodily tissue, especially an organ such as a lung, by adjusting pressure as needed to maintain a constant pressure within the organ even during external pressure fluctuations due, for example, to transportation of the organ in an airplane. Gas passing into and out of the organ may be conditioned to prolong tissue viability.

The invention provides, in various embodiments, devices and methods relating to ex-vivo organ care. In certain embodiments, the invention relates to aortic cannulas for use in perfusion systems to return perfusate to the heart or delivering perfusate from the heart while the organ is sustained ex vivo at physiologic or near-physiologic conditions.

A system for the hypothermic transport of biological samples, such as tissues, organs, or body fluids. The system includes an antimicrobial treatment mechanism to inactivate microbes flushed from the biological sample by preservation fluid flowed therethrough. 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 while simultaneously treating microbial infections to prevent transmission between a donor and a recipient.

A system for the hypothermic transport of biological samples, such as tissues, organs, or body fluids. The system includes support systems to permit arrangement of cooling media around a biological sample without potentially damaging direct contact between the cooling media and the biological sample. Systems and methods disclosed herein also include specific configurations, types, and performance characteristics of cooling media such as phase change materials to allow for extended hypothermic storage and transport.
