  • Patent number: 10066198
    Abstract: A device for in-vitro modelling in-vivo tissues of organs that includes a first body portion with at least one access chamber, a second body portion with at least one culturing chamber, and a culturing membrane dividing the at least one access chamber from the culturing chamber. The device further includes a third body portion with at least one actuation chamber having at least one limitation cavity, and an actuation membrane dividing the at least one culturing chamber from the at least one actuation chamber. With the device, a robust actuation system can be provided that does not depend on the mechanical properties of the actuation membrane material, nor on the pressure, and that allows to mimic three-dimensional deformations of the tissue, in particular of lung alveoli.
