1. A venous valve, comprising:
- a frame including an elongate member having a first member end, a second member end, a predetermined portion adjacent the first member end, and a predetermined portion adjacent the second member end, wherein the predetermined portions adjacent the first and the second member ends entwine to close a circumference of the entire frame, wherein the predetermined portions include a width different than the width of other portions of the frame such that where the predetermined portions are entwined the width of the entwined predetermined portions is no greater than the width of the other portions of the frame, and wherein the first and second member ends extend radially from an outer surface of the frame; and
a cover on the frame, wherein the cover includes surfaces defining a reversibly sealable opening for unidirectional flow of a liquid through the valve.
