Vascular device for treating venous valve insufficiency

A vascular device insertable into a vessel for treating vein valve insufficiency comprising:

• a support having a first upstream portion, a second downstream portion and an intermediate portion between the upstream portion and the downstream portion, the support including first and second elongated portions positioned on opposite sides of the intermediate portion such that the first and second elongated portions extend axially from the intermediate portion;
• a first looped retention portion at the first upstream portion, the first looped retention portion movable from a first elongated insertion position to an expanded position;
• a second looped retention portion at the second downstream portion, the second looped retention portion movable from a first elongated insertion position to an expanded position:
• a third looped portion positioned between the first looped portion and the second looped portion, the third looped portion movable to different diameters dependent on an inner diameter of a vessel wall of the vessel;
• and
• a valve supported by the third looped portion such that the support does not extend axially through the valve, the valve being movable between an open position to allow blood flow therethrough and a closed position to inhibit blood flow therethrough, wherein the valve is moved to different diameters dependent on the diameter of the third looped portion which is dependent on the inner diameter of the vessel wall.
