Abstract:
1. A prosthetic stented heart valve comprising: a radially compressible and expandable tubular metal frame structure having a longitudinal axis and extending from an inflow end along the longitudinal axis to an outflow end along the longitudinal axis; a first material layer positioned inside of the metal frame structure and extending longitudinally at least to the inflow end of the metal frame structure, the first material layer secured to the metal frame structure; and a leaflet structure comprising dual-layer materials forming a generally tubular shape, the leaflet structure permits fluid flow from the inflow end of the metal frame structure through the leaflet structure and for preventing fluid flow through the leaflet structure back toward the inflow end of the metal frame structure, the leaflet structure comprising a plurality of leaflets, each leaflet structure comprising a second material layer provided inside of the first material layer and having an arcuate edge sutured to at least an inner surface of the first material layer, an open edge spaced from the arcuate edge, and opposite side edges extending from the arcuate edge, each of which is operatively connected to a side edge portion of an adjacent leaflet between the arcuate edge and the open edge; wherein the plurality of leaflets are longitudinally positioned between the inflow and outflow ends of the metal frame structure and are longitudinally spaced from the inflow end.
