Abstract
A replacement heart valve structure including a structure of tissue which is an intact, mammalian heart valve that has been harvested and treated to preserve it. A conventional fabric sleeve is typically disposed concentrically around the outside of the tissue structure. A support structure is included to facilitate implanting the heart valve by somewhat increasing the stability of the heart valve structure, but without unduly rigidifying it. An annular sewing cuff may be added adjacent the blood inflow end of the valve structure to facilitate making the annular suture line that is required at that end.
