An elongated frame dimensioned and configured for implantation in a blood vessel. The frame has two axially spaced apart ring portions, which may be in the form of an expandable crown or a similar structure. At least one linking member connects the two ring portions to one another to form an integral structure. A valve membrane is supported between the axially spaced apart ring portions of the frame. The valve membrane is adapted and configured for movement between a first position in which blood flow through the frame is permitted and a second position in which blood flow through the frame is inhibited.
