Abstract
An apparatus for shunting blood includes a flow-indication chamber shaped to define an entry port and an exit port, and one or more moveable objects disposed within the flow-indication chamber and configured to move in response to a flowing of the blood from the entry port to the exit port. At least a portion of a wall of the flow-indication chamber is transparent so as to expose the moveable objects to sight. Other embodiments are also described.
