  • Publication number: 20050130297
    Abstract: A device for culturing cells and tissue comprises at least one culture well (18-i), first and second reservoirs (2 and 25) each housing at least one flexible bag (6, 7; 27, 29), at least one of which is suitable for receiving a culture fluid, link means (20, 21) coupled to the wells and to the bags to allow culture fluid to flow from one reservoir to the other via the well, pressurization means (60-92) subjecting the first and second reservoirs (2 and 25) respectively to first and/or second sequences of external pressures defined by a control module (50) for the purpose of governing the flow of culture fluid in the well, and temperature regulation means (49, 51-58) controlled by the control module and arranged to maintain a first selected temperature inside the well and to subject the culture fluid leaving the first and second reservoirs in order to feed the well to a second selected temperature.

  • Patent number: 6271027
    Abstract: A cell and tissue culture device comprises several culture wells (18-i) accommodating cells and tissues to be grown, of first (2) and second (25) tanks, and connecting means (20,23,24) coupled to wells and tanks so as to enable a culture fluid to flow from one tank to another via the wells. Each tank (20,25) accommodates at least a flexible pocket (6,7;27,29), at least one of which is able to receive the culture fluid. The device further comprises at least a controller module (50,150) providing first and/or second sequences of external pressures to be applied, on the pockets of first and second tanks, respectively, and pressurization means (41,46-49) configured for applying to the pockets, pressures defined by said first and second sequences provided by the controller module.
