Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. The transition portion includes a plurality of axial frame members, and three of the plurality of the axial frame members are commissure posts. At least two of the plurality of the axial frame members are commissure posts having a first end connected to a crown of the inflow portion and an unattached second end disposed within the outflow portion such that a pair of struts of the outflow portion intersect each commissure post at a mid-portion thereof. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent.

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 transcatheter heart valve prosthesis and a method of assembling the transcatheter heart valve prosthesis are disclosed. The heart valve prosthesis includes a valve-skirt assembly having an inner skirt, a frame, an outer wrap backing and an outer wrap. The method includes: tacking the valve-skirt assembly within the frame; attaching the inner skirt below commissure posts of the frame; attaching commissures of the valve component to the commissure posts; attaching a plurality of outer wrap backings to the inner skirt; attaching the outer wrap backings and the inner skirt to the frame; attaching tissue bumpers to struts in an outflow section of the frame; attaching an outer wrap and the inner skirt to the frame; attaching the outer wrap to the inner skirt proximate inflow edges thereof; and attaching the outer wrap to the inner skirt and to the outer wrap backings proximate respective outflow edges thereof.

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.
