Abstract: An implantable valve system comprises a flexible tube and a flexible valve structure. The flexible tube and flexible valve structure can be made of a synthetic polymer material. The flexible valve structure is disposed within the flexible tube. The flexible valve structure can comprises a first leaflet, a second leaflet, and a valve orifice between the first leaflet and the second leaflet. Additional leaflets are possible. Each of the first leaflet and the second leaflet comprises an upper portion forming the valve orifice and a lower portion attached to the flexible tube. The valve orifice has a maximum circumference less than an internal circumference of the flexible tube.

Abstract: A vascular valve constructed from a biocompatible material that is designed to be surgically implanted in a patient's blood vessel, such as the right ventricular outflow tract. At the first end of the valve there is an orifice defined by at least two opposing free edges, and which can occupy either a first, closed position or a second, open position. At the second end of the valve there are at least two flexible members attachable to an anterior and a posterior wall of a patient's blood vessel. A length of the orifice between said at least two opposing free edges when the orifice is generally closed is equal to about 1.5 to 2 times the diameter of a patient's blood vessel. Optionally, the two flexible members to a stent or tubular graft. The valved stent or tubular graft can be inserted into a patient's blood vessel or heart.

Abstract: A heart valve constructed from a synthetic resin that is designed to be surgically implanted in the right ventricular outflow tract of the heart comprising a plurality of flexible members, and an orifice.
