A valve that has at least one internal port on a valve core and at least one an internal slot in a valve body. The endoscope and the fluid management system are synergistic to each other such that both enhance the efficiency of each other. A dead loop is formed in the energy absorbing member between its mounting location and the first anvil and is operative to enable the dead loop to straighten in response to application of an applied force prior to movement of the energy absorbing member across the first anvil. Banks are formed by patterning the bank material layer, and forming a resin film on a surface of the first layer by attaching a portion of the bank material layer to the first layer.
