Abstract
An arterial shunt is disclosed having means for indicating the flow of blood through the shunt. The shunt comprises a movable indicator element responsive to the flow of blood. Whether or not blood is flowing through the shunt may be quickly and easily ascertained by visual inspection of the indicator element through a transparent window. Alternatively, electromagnetic or optical means may be employed to measure the velocity of the movement of the indicator element which also allows the rate of blood flow through the shunt to be quantified.
