ABSTRACT:
An improved heart valve having an annular valve housing and two leaflets supported for pivotable movement within the annular valve housing. Each leaflet is pivoted about an axis displaced from the center of the valve housing. When open, the leaflets pivot away from the center of the valve housing allowing for central flow. The valve leaflets are provided with curved indentations with engage curved projections from the valve housing which serve both to retain the valve leaflets within the housing and to define and control their pivotal movement during opening and closing.
