17. A method of radially compressing a prosthetic valve, comprising:
partially inserting the valve while in a radially expanded configuration into a crimping device comprising crimper jaws such that a portion of the valve comprising an outer skirt extends outside of the crimper jaws, wherein the valve comprises:
a frame; and
the outer skirt positioned around an outer surface of the frame, the outer skirt comprising an inflow edge secured to the frame at a first location on the frame, an outflow edge secured to the frame at a second location on the frame, and an intermediate portion between the inflow edge and the outflow edge that comprises slack that buckles radially outwards from the inflow and outflow edges of the outer skirt when the valve is in the radially expanded configuration;
crimping the valve to a first partially collapsed configuration such that partial flattening of the outer skirt against the frame occurs;
further inserting the valve into the crimping device, such that the outer skirt is between the crimper jaws; and
crimping the valve to a second partially collapsed configuration such that additional flattening of the outer skirt against the frame occurs, wherein a distance between the outflow edge and the inflow edge of the outer skirt is larger in the second partially collapsed configuration than in the first partially collapsed configuration.
