In one embodiment, the device has a substantially flat valve unit and a substantially flat filter unit. In another embodiment, the device has at least one open umbrella deployed configuration. In one aspect, the device has a unitary construction with one umbrella canopy with one or more filter areas with flaps allowing unidirectional blood flow. In another aspect, the device has a valve unit and filter unit, the umbrella canopies oriented in opposite directions, and the valve unit “closes” and opens to allow blood to flow to one direction.
