Claim Text:
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 edge along the longitudinal axis to an outflow edge along the longitudinal axis; and a valve segment comprising a multi-layer portion defining an inflow edge of the valve segment and a single-layer portion defining an outflow edge of the valve segment that are formed into a generally tubular shape and provide a plurality of leaflet pockets, each leaflet pocket comprising a first material layer of the multi-layer portion attached to a second material layer of the multi-layer portion with the plurality of leaflet pockets arranged together in the generally tubular shape and providing a leaflet-defining pattern that is longitudinally spaced from the inflow edge of the metal frame structure and that permits fluid flow from the inflow edge of the metal frame structure through the leaflet-defining pattern and that prevents fluid flow back through the leaflet-defining pattern toward the inflow edge of the metal frame structure, each leaflet pocket comprising an arcuate portion having a continuous arc extending from the first side edge portion to the corresponding second side edge portion, and an open edge spaced longitudinally from the arcuate portion between the first and second side edge portions, the entire arcuate portion being longitudinally spaced apart from the inflow edge of the valve segment; wherein at least a portion of the valve segment is longitudinally positioned within the metal frame structure, and wherein the metal frame structure is attached to the first material layer of at least one leaflet pocket with the first material layer extending longitudinally at least to the inflow edge of the metal frame structure.
