Abstract
A valve including a living hinge coupling a leaflet to a valve body. The leaflet can be coupled through the living hinge to the valve body's inner diameter, its outer diameter, or somewhere between the two diameters. Because the living hinge design of the valve is an integrated part, it can be manufactured in a single step.
