    Abstract: A delivery apparatus for an expandable prosthetic heart valve includes a handle, and a shaft having a proximal end portion coupled to the handle and a distal end portion including a delivery capsule. The delivery capsule having an inner surface, an outer surface, and a plurality of elongate and axially extending inner and outer guide rails, the inner guide rails being spaced apart circumferentially around and extending radially inwardly from the inner surface and the outer guide rails being spaced apart circumferentially around and extending radially outwardly from the outer surface. The inner guide rails are configured to engage the prosthetic heart valve in a radially-compressed configuration and the outer guide rails are configured to contact an inner surface of an outer shaft.

    Abstract: A transcatheter delivery system including an expandable transition element is disclosed. As one example, an assembly may comprise a prosthetic valve and a delivery device. The delivery device may comprise an outer shaft with a distal end portion forming a sheath adapted to enclose the prosthetic valve therein in a radially compressed configuration; an inner shaft arranged within the outer shaft and including a nosecone arranged at a distal end of the inner shaft, the nosecone arranged outside of the outer shaft, at the distal end portion of the outer shaft; and an expandable transition element adapted to expand from a non-expanded state within the outer shaft to an expanded state outside the outer shaft, wherein, in the expanded state, the transition element forms a continuous transition from the nosecone to the prosthetic valve when the sheath is moved away from the nosecone to uncover the prosthetic valve.

    IPC: A61F2/24

    Abstract: An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration includes an annular frame including a plurality of angled strut members, a plurality of leaflets disposed within the frame and secured to the frame, and a skirt member secured to the frame. The skirt member is disposed about an edge portion of a leaflet of the plurality of leaflets, and the skirt member includes a plurality of extension portions wrapped around at least one strut member. A cord member is threaded through at least a portion of the plurality of extension portions in a direction along an axis of the at least one strut member to secure the skirt member to the at least one strut member.

    Abstract: In one embodiment, a prosthetic valve can comprise a radially expandable and compressible frame, which can include a plurality of struts which are pivotally joined together without requiring individual rivets. In some embodiments, the struts are interwoven, and can be joined using integral hinges formed in the struts, such as by performing alternate cuts on the struts, bending the struts to form stopper tabs adjacent to joints and/or drilling holes in the struts to facilitate interconnecting struts at joints, or otherwise forming integral hinges and corresponding holes at junction points between the struts. In another embodiment, the frame comprises a plurality of inner struts and outer struts which are connected by a plurality of chains of interconnected rivets, avoiding the need to provide individual rivets at each junction between struts. In still another embodiment, separate hinges or flanged rivets are provided to interconnect the struts.
