1. An implantable device for regulating blood flow through a blood vessel, comprising:
- a) an elongated support dimensioned and configured to be implanted in a blood vessel, the support including axially spaced apart first and second support portions, and at least one linking member connecting the axially spaced apart portions to one another; and
b) a valve membrane including a body portion and a neck portion extending therefrom, the body portion attached to one of the first and second support portions and the neck portion being attached to the other of the first and second support portions, the valve membrane adapted for movement between a first position wherein the body portion extends substantially across the elongated support with the neck portion in close proximity with a wall of the blood vessel inhibiting blood flow through the support, and a second position wherein the neck portion moves away from a wall of the blood vessel permitting blood flow through the support, in the first position the valve membrane having a convex outer surface and in the second position the valve membrane having a wavy shape.

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

11. An implantable device for regulating blood flow through a blood vessel, comprising:
-
a) an elongated support dimensioned and configured to be implanted in a blood vessel, the support including first and second axially spaced apart portions and a curved linking member joining the first and second portions at about 90 degrees apart; and b) a valve membrane including a body portion and a neck portion extending therefrom, the body portion attached to one of the first and second support portions and the neck portion being attached to the other of the first and second support portions, the valve membrane adapted for movement between a first position wherein the body portion extends substantially across the elongated support with the neck portion in close proximity with a wall of the blood vessel inhibiting blood flow through the support, and a second position wherein the neck portion moves away from a wall of the blood vessel permitting blood flow through the support. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An implantable device for regulating flow within a body, comprising:
-
a) an elongated support dimensioned and configured to be implanted in a tubular structure of the body, the support including axially spaced apart first and second support portions, and at least one linking member connecting the axially spaced apart portions to one another; and b) a valve membrane including a body portion and a neck portion extending therefrom, the body portion attached to one of the first and second support portions and the neck portion being attached to the other of the first and second support portions, the valve membrane adapted for movement between a first position wherein the body portion extends substantially across the elongated support with the neck portion in close proximity with a wall of the tubular structure inhibiting blood flow through the support, and a second position wherein the neck portion moves away from a wall of the tubular structure permitting blood flow through the support. - View Dependent Claims (20, 21)
