Abstract: A crimper configured to radially compress a transcatheter valve prosthesis into a crimped configuration for delivery within a vasculature. The transcatheter valve prosthesis includes a frame and at least one leaflet secured within the frame. The crimper is configured to apply pressurized fluid to the at least one leaflet of the transcatheter valve prosthesis during the crimping process to prevent protrusion of the leaflet into the frame of the transcatheter valve prosthesis that may cause leaflet pinching and damage. The crimper includes a plurality of crimper elements that collectively define a crimper chamber of the crimper, and at least one crimper element of the plurality of crimper elements includes an integral channel extending therethrough for applying the pressurized fluid to the at least one leaflet.

Abstract: A leaflet folding accessory or tool configured for use with a crimper when radially compressing a transcatheter valve prosthesis into a crimped configuration for delivery within a vasculature. The crimping accessory is configured to apply or remove fluid to or from the at least one leaflet of the transcatheter valve prosthesis during the crimping process to prevent protrusion of the leaflets into the frame of the transcatheter valve prosthesis that may cause leaflet pinching and damage.
