Abstract
A prosthetic valve includes an annular frame and a skirt. The frame is radially expandable and compressible between a radially compressed configuration and a radially expanded configuration. The skirt has a fold around an inflow end of the frame so as to cover at least a portion of an outer surface of the frame and at least a portion of an inner surface of the frame. When the frame is in the radially expanded configuration, an outer portion of the skirt tightly conforms to the outer surface of the frame and the inflow end of the frame is axially spaced from the fold to form an axially extending gap between the frame and the fold. When the frame is in the radially compressed configuration, the inflow end of the frame extends axially so as to at least partially fill the axially extending gap.
