Abstract
A pressure activated valve comprises a valve housing defining a lumen for receiving bodily fluids therein and a flexible membrane disposed in the valve housing. The flexible membrane includes a slit extending therethrough so that the flexible membrane may be moved between an open and a dosed configuration based on fluid pressure within the lumen. A nonthrombogenic coating may be formed on fluid contacting surfaces of the flexible membrane.
