Abstract: Devices and methods for reinforcing a tissue-based heart valve are provided. A reinforced tissue valve can provide structure and rigidity to withstand stresses that occur within the vasculature. In some instances, thickened tissue provides structure or rigidity. In some instances, a biocompatible filler is utilized within folded, rolled, or layered tissue. In some instances, a mesh is included with a reinforced tissue valve for further strength. In some instances, a mesh frame is utilized along the sidewall of a tissue-based heart valve. In some instances, a leaflet assembly is provided within a conduit having thickened tissue at the leaflet commissures.
