1. An implantable device for regulating blood flow through a blood vessel, comprising:
- a) an elongated frame dimensioned and configured to be implanted in a blood vessel, the frame including axially spaced apart ring portions, and at least one linking member connecting the axially spaced apart ring portions to one another; and
b) a valve membrane supported between the axially spaced apart ring portions of the frame and adapted 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.

Abstract
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.
