Abstract
A retrograde flow system is configured for treating an artery. The system includes an arterial access device adapted to be introduced into an artery and receive blood flow from the artery. A shunt fluidly is 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 is coupled to the shunt and is adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state. A shut-off valve assembly automatically blocks fluid flow through the shunt in response to injection of the fluid into the arterial access device.
