1. A system for ex vivo testing performance of a hemostatic or sealing product attached to an animal organ and fully covering a cored channel in said organ, comprising:
a) a pressure sensor positioned proximate to said hemostatic or sealing product in said cored channel;
b) a monitoring or recording device configured to receive pressure readings from said pressure sensor; and
c) a pressurized fluid source connected to said cored channel and configured to supply said pressurized fluid into said cored channel under constant or variable pressure.
