A system for applying controlled pressure profiles to biological samples is disclosed. It includes at least one chamber (20), which can receive first and second biological samples (78) and receive a gas from its source (34). One sample can be in first chamber (20), the other is in second chamber (24), or both are in one chamber. A controller (32) is provided to control pressure in at least one chamber. A sensor (26) detects a pressure differential and transmits signal to the controller. A flow adjustment device (16) adjusts the flow of gas into the first chamber, controls gas's flow in response to sensor's signal, and applies a pre-selected pressure to at least one chamber. A pressure dampener is provided to reduce pressure oscillations in chambers. Also disclosed are method to detect a pressure-induced change in soft tissue sample and method of evaluating the efficacy of substance in treating effects of high-pressure in sample.
