Abstract
A multi-sample biologic material stimulation and characterization system includes individual flow paths for each sample. Each individual flow path can maintain sterile conditions and may be chemically monitored. The mean flow rate and pulsatile flow rate through each sample may be individually controlled. Pressure at the sample is controlled independently of the flow rate through downstream variable flow restrictors. An axial force may be applied to each sample. A radial force may be applied via hydrostatic pressure of chamber fluid surrounding each sample. A real-time controller manages the system and saves information gathered from the transducers and actuators of the system.
