Abstract
A heart valve assembly has a frame comprising an anchoring section, a generally cylindrical leaflet support section, and a neck section that transitions between the anchoring section and the valve support section. The anchoring section has a ball-shaped configuration defined by a plurality of wires that extend from the leaflet support section, with each wire extending radially outwardly to a vertex area where the diameter of the anchoring section is at its greatest, and then extending radially inwardly to a hub. A plurality of leaflets are stitched to the leaflet support section. The heart valve assembly is delivered to the location of a native pulmonary trunk, the vertex area of the anchoring section is deployed into the native pulmonary arteries such that the vertex area is retained in the pulmonary arteries, and then the leaflet support section is deployed in the pulmonary trunk.
