1. An implantable medical device for regulating fluid flow through a body vessel, comprising:
- a support frame having radially compressed and radially expanded configurations;
means forforming a leak path between the support frame and an interiorwall of said body vessel; and
at least one flexible valve member attached to the support frame, the valve member moveable between a first position that permits said fluid flow in a first direction and a second position that substantially prevents said fluid flow in a second direction.

Abstract
Medical devices that provide valves for regulating fluid flow through a body vessel are provided. The valves include a support frame having one or more adaptations for forming a leak path between the support frame and an interior wall of a body vessel in which the valve is implanted. A controlled amount of retrograde flow is able to flow through the leak path when the valve is implanted in a body vessel.

14. An implantable medical device for regulating fluid flow through a body vessel, comprising:
-
a support frame having radially compressed and radially expanded configurations;
means forforming a leak path between the support frame and an interiorwall of said body vessel; and
a first flexible valve member attached to the support frame and having first and second edges, the first edge attached to the support frame and the second edge being free of the support frame; and
a second flexible valve member attached to the support frame and having third and fourth edges, the third edge attached to the support frame and the fourth edge being free of the support frame;
wherein the second and fourth edges cooperatively defining a closeable valve opening through which said fluid flow can pass. - View Dependent Claims (15, 16, 17, 18)

19. An implantable medical device for regulating fluid flow through a body vessel, comprising:
-
a support frame having radially compressed and radially expanded configurations and defining an interior space, the support frame defining adaptations that space a portion of the support frame from an interior wall of said body vessel to form a leak path between the support frame and an interior wall of said body vessel; and
a tubular graft member attached to the support frame and having first and second ends, the first end defining a valve orifice that permits said fluid flow in a first direction and a second position that substantially prevents said fluid flow in a second direction. - View Dependent Claims (20)
