  • Patent number: 9478020
    Abstract: Disclosed are methods for analyzing the effect of a test substance on biological and/or biochemical samples in which a plurality of samples, each comprising a known concentration of the test substance in at least three different concentrations, are used to obtain measurements which provide raw data. An evaluation rule utilizes the raw data of the sample determining the effect of the test substance, at the particular concentration, on the sample. The evaluation rule is influenced by at least one control parameter, and at least one starting value for the at least one control parameter is determined. The raw data is evaluated and correspondence between the determined activities and a functional model resulting from theoretical considerations yields a dose/effect curve describing the dependence of the activities on the concentration of the test substance. The steps are modified and repeated until an abort criterion has been reached.

  • Patent number: 9005958
    Abstract: A cultivation apparatus and a cultivation method of a culture such as a cell or tissue. Provided are an incubator unit for accommodating a culture and a lever that penetrates through the incubator unit and can move in circular arc around a fulcrum as a center, the fulcrum being set at a wall of the incubator unit or in the vicinity thereof, then displacement is imparted to the culture by operating the lever. Bending force can be acted on the culture (cell construct) such as a cell or tissue, so that without any increase or decrease of a culture fluid in the incubator unit, namely, without any increase or decrease of pressure to the culture fluid, displacement required for cultivation can be imparted to the culture in the incubator unit. By curving, continuous compression and extension are generated in a direction of thickness from a concave portion to a convex portion of the curving.

  • Publication number: 20150093812
    Abstract: A bioartificial filtration organ can be produced from an organ scaffold by re-seeding the scaffold with endothelial cells or cell progenitors and with epithelial cells or cell progenitors in a negative pressure environment. The negative pressure encourages the re-seeding over a greater extent of the scaffold.

  • Patent number: 8986978
    Abstract: A system and method for regulating cooperatively the pressures and flows of input vessels such as both the portal vein and hepatic artery for the liver. This invention solves problems of less-than-therapeutic portal vein flow during perfusion preservation by implementing cooperative regulation between the inputs, e.g., portal vein and hepatic artery pumping systems, on an organ preservation apparatus. It includes an algorithm that adapts to the situation wherein the portal vein has reached minimum flow and maximum pressure. The cooperative regulation algorithm senses the problem with the portal vein and solves it by adjusting the hepatic artery flow conditions.

  • Patent number: 8962303
    Abstract: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. In perfusion, organ perfusion pressure is preferably controlled in response to a sensor disposed in an end of tubing placed in the organ, by a pneumatically pressurized medical fluid reservoir, providing perfusion pressure fine tuning, overpressurization prevention and emergency flow cut-off. In the hypothermic mode, the organ is perfused with a medical fluid, preferably a simple crystalloid solution containing antioxidants, intermittently or in slow continuous flow. The medical fluid may be fed into the organ from an intermediary tank having a low pressure head to avoid organ overpressurization. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate.
