1. A stentless prosthetic heart valve, comprising:

  • a plurality of thin, flexible leaflets, each of the leaflets having an inner face, an outer face, an in-flow edge, an out-flow edge, and side edges, the plurality of leaflets being sewn directly together along at least a portion of their side edges so as to form a substantially tubular valve structure having an in-flow end and an out-flow end, adjacent leaflets being arranged so that their side edges are substantially aligned and the inner faces of the leaflets engage each other adjacent the side edges, wherein the valve structure is movable between a closed position in which the out-flow edges of adjacent leaflets engage each other, and an open position in which the out-flow edges of adjacent leaflets are separated from each other except along the side edges, the sewn portions of the side edges of the leaflets biasing the leaflets toward a partially closed position.
