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.
