SYSTEMS AND METHODS FOR ASPIRATING FROM A BODY LUMEN
An aspiration device can be used to aspirate an obstruction from a blood vessel. The aspiration device is configured to allow controlled one- handed aspiration yet maintain a syringe plunger feel of vacuum. The aspiration device also allows one-handed injection to empty the device when needed. Furthermore, mechanisms enable one-handed locking of a plunger position of the device to maintain vacuum when the user releases the device.

SYSTEM AND METHODS FOR CONTROLLING RETROGRADE CAROTID ARTERIAL BLOOD FLOW
A retrograde flow system (100) is configured for treating an artery. The system includes an arterial access device (110) adapted to be introduced into an artery and receive blood flow from the artery. A shunt (120) 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 (125) 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 (1115) automatically blocks fluid flow through the shunt in response to injection of the fluid into the arterial access device.
