    Abstract: A skirt-reinforcement member for supporting or reinforcing an unsupported portion of a skirt that spans across a side opening of a stent or frame of a valve prosthesis. The skirt-reinforcement member is configured to prevent billowing of the skirt material that spans across the side opening of the inner frame of the valve prosthesis, as such billowing may undesirably result in contact between the skirt and leaflets of the valve prosthesis after the valve prosthesis is deployed in situ.

    Abstract: Composite skirts for a stent or frame of a valve prosthesis are configured to prevent billowing of the skirt material that spans across the side openings of the frame of the valve prosthesis, as such billowing may undesirably result in contact between the skirt and leaflets of the valve prosthesis after the valve prosthesis is deployed in situ. In a first embodiment, a composite skirt is formed by alternating first and second segments of a first stiffness and a second stiffness, respectively, that alternate in a circumferential direction. The second stiffness is higher than the first stiffness. Each segment of the alternating first and second segments extends in an axial direction for substantially an entire length of the composite skirt. In a second embodiment, a multi-layer skirt is formed by a porous fabric material and a thin polymeric coating covering the fabric material.

    Abstract: An assembly including a transcatheter valve prosthesis and a leaflet folding accessory configured for use when compressing the transcatheter valve prosthesis into the crimped configuration. The transcatheter valve prosthesis includes a stent and a prosthetic valve component including at least one leaflet disposed within and secured to the stent. The transcatheter valve prosthesis has a crimped configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The leaflet folding accessory includes a plurality of guide fingers. Each guide finger is configured to contact the prosthetic valve component and hold the at least one leaflet in a predetermined configuration when the transcatheter valve prosthesis is compressed into the crimped configuration.

    Abstract: A prosthesis includes a frame and a skirt coupled to a surface of the frame. The skirt extends over at least one side opening of a plurality of side openings of the frame. The prosthesis also includes a skirt-reinforcement member that spans the at least one side opening from a first crown or strut edge defining the at least one side opening to a second crown or strut edge defining the at least one side opening. The skirt-reinforcement member has a first end, a second end, and a length therebetween. The first end of the skirt-reinforcement member is attached to the first crown or strut edge and the second end of the skirt-reinforcement member is attached to the second crown or strut edge. The skirt-reinforcement member is attached to the skirt along an unsupported portion of the skirt that spans the at least one side opening.
