1. A prosthetic valve, comprising:
- a radially compressible and expandable annular frame;
a leaflet structure comprising a plurality of leaflets supported within the frame and configured to regulate the flow of blood through the prosthetic valve in one direction; and
a skirt disposed around an outer surface of the frame and configured to seal against surrounding tissue when the prosthetic valve is implanted in a patient'"'"'s body, wherein the skirt comprises an elastomer;
wherein the skirt comprises a first layer comprised of the elastomer and a second layer comprised of a fabric.

Abstract
A method of crimping an implantable prosthetic valve can include placing protective material over at least a portion of the implantable prosthetic valve. The protective material can be configured to occupy space between open cells of a frame of the implantable prosthetic valve to prevent damage to a leaflet structure of the implantable prosthetic valve. The method can also include crimping the implantable prosthetic valve with the protective material on the implantable prosthetic valve, and removing the protective material from between the frame and the leaflet structure of the implantable prosthetic valve.
