Abstract
Embodiments of a radially collapsible and expandable prosthetic heart valve and method for crimping the prosthetic heart valve are disclosed. A method of radially compressing a prosthetic valve can include partially inserting the valve while in a radially expanded configuration into a crimping device comprising crimper jaws, wherein a portion of the valve comprising an outer skirt extends outside of the crimper jaws. The method can further include crimping the valve to a first partially collapsed configuration, 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, wherein a diameter of the valve is smaller in the second partially collapsed configuration than in the first partially collapsed configuration.
