Abstract:
1. A two-piece prosthetic valve assembly, consisting of: a bioremodelable first conduit member having first and second ends, and an internal lumen, said first conduit member lumen having an inner surface; and a separate bioremodelable second conduit member having first and second ends, and an internal lumen, said first and second conduit members comprising an extracellular matrix (ECM) material from a mammalian tissue source, said tissue source comprising small intestine submucosa (SIS), said first end of said first conduit member being configured to receive said second end of said second conduit member therein, wherein said second end of said second conduit member is disposed in said first end of said first conduit member, said second end of said second conduit member being directly attached to said first conduit member lumen inner surface at a first commissure connection point, wherein said first conduit member lumen and said second conduit member lumen are in communication, and wherein a first valve leaflet is formed by said second end of said second conduit member within said first conduit member lumen, said first valve leaflet being configured to selectively restrict fluid flow through said two-piece valve assembly, and wherein, following attachment of said valve assembly to a cardiovascular vessel, said first and second conduit members are remodeled by cardiovascular tissue to form an integral valve member comprising remodeled cardiovascular tissue.
