Abstract: An organomimetic device includes a microfluidic device that can be used to culture cells in its microfluidic channels. The organomimetic device can be part of dynamic system that can apply mechanical forces to the cells by modulating the microfluidic device and the flow of fluid through the microfluidic channels. The membrane in the organomimetic device can be modulated mechanically via pneumatic means and/or mechanical means. The organomimetic device can be manufactured by the fabrication of individual components separately, for example, as individual layers that can be subsequently laminated together.

Abstract: Provided herein relates to systems and methods for producing and using a body having a central channel separated by one or more membranes. The membrane(s) are configured to divide the central channel into at least one mesochannel and at least one microchannel. The height of the mesochannel is substantially greater than the height of the microchannel. A gaseous fluid can be applied through the mesochannel while a liquid fluid flowing through the microchannel. The systems and methods described herein can be used for various applications, including, e.g., growth and differentiation of primary cells such as human lung cells, as well as any other cells requiring low shear and/also stratified structures, or simulation of a microenvironment in living tissues and/or organs (to model physiology or disease states, and/or to identify therapeutic agents and/or vaccines). The systems and methods can also permit co-culture with one or more different cell types.

Abstract: The invention provides integrated Organ-on-Chip microphysiological systems representations of living Organs and support structures for such microphysiological systems.

Abstract: A microfluidic system includes a microfluidic device connected to a bubble trap device whereby fluid flowing to the microfluidic device passes through the bubble trap device to remove gas bubbles prior to entering the microfluidic device. The bubble trap can include a separation chamber and an exhaust chamber separated by a hydrophobic porous membrane and gas bubbles in the fluid entering the separation chamber pass through the hydrophobic porous membrane into the exhaust chamber while the fluid remains in the separation chamber. The bubble trap can be formed by bonding a first body portion to a first side of the hydrophobic porous membrane and bonding a second body portion to a second side of the hydrophobic porous membrane. The exhaust chamber can be connected to an elongated exhaust channel that limits the evaporation losses of the fluid through the hydrophobic porous membrane.

Abstract: The invention provides integrated Organ-on-Chip microphysiological systems representations of living Organs and support structures for such microphysiological systems.

Abstract: Disclosed herein are organ chips that can be individually used or integrated together to form different microphysiological systems, e.g., for use in cell culturing, drug screening, toxicity assays, personalized therapeutic treatment, scaffolding in tissue repair and/or replacement, and/or pharmacokinetic or pharmacodynamics studies.

Abstract: Described herein are microfluidic modules and methods for making the same, wherein the microfluidic modules include a substrate comprising at least one ether-based, aliphatic polyurethane, and at least one fluidic element disposed therein. The ether-based aliphatic polyurethane can be either the substrate of the microfluidic modules or a coating of another substrate material, such that at least a portion of the ether-based, aliphatic polyurethane is in fluid communication. In one embodiment, the ether-based, aliphatic polyurethane includes dicyclohexylmethane-4,4?-diisocyanate. As the ether-based aliphatic polyurethane can decrease absorption of molecules, e.g., hydrophobic molecules, in such microfluidic modules, the microfluidic modules described herein can be used in various applications such as drug screening and fluorescent microscopy.

Abstract: The technology described herein is directed to methods and devices that can be used to induce functional organ structures to form within an implantation device by implanting it in vivo within the body of a living animal, and allowing cells and tissues to impregnate the implantation device and establish normal microenvironmental architecture and tissue-tissue interfaces. Then the contained cells and tissues can be surgically removed intact and either transplanted into another animal or maintained ex vivo by perfusing it through one or more of the fluid channels with medium and/or gases necessary for cell survival.

Abstract: The present invention is directed to systems and methods for delivering aerosolized micro-droplets into microfluidic devices. In some embodiments, the microfluidic devices are designed for the culture of living cells at an air interface. In some embodiments, the systems and methods described herein can be used to deliver aerosolized micro-droplet into detection systems and small animals, tissues, organs and organisms.
