1. A retrograde flow system for treating an artery, comprising:

  • an arterial access device adapted to be introduced into an artery and receive blood flow from the artery;

    a shunt fluidly connected to the arterial access device, wherein the shunt provides a pathway for blood to flow from the arterial access device to a return site;

    a flow control assembly coupled to the shunt and adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state; and

    a shut-off valve assembly that regulates fluid flow through the shunt, wherein the shut-off valve assembly automatically blocks fluid flow through the shunt in response to injection of the fluid into the arterial access device.
