  • Patent number: 10653540
    Abstract: The present disclosure comprises a highly conformable stent graft with an optional portal for a side branch device. Said stent graft comprises a graft being supported by a stent, wherein said stent comprises undulations each which comprise apices in opposing first and second directions and a tape member attached to said stent and to said graft such that the tape member edge is aligned to the edge of the apices in the first direction of the each of the undulations, thus confining the apices in the first direction of the undulations to the graft and wherein the apices in the second direction of the undulation are not confined relative to the graft; wherein said graft forms unidirectional pleats where longitudinally compressed and wherein said apices in the first direction of said undulation is positioned under an adjacent pleat when compressed.

  • Publication number: 20190269505
    Abstract: Described embodiments are directed toward prosthetic valves and systems and methods of making prosthetic valves. In accordance with an embodiment, a prosthetic valve comprises and leaflet frame, and outer frame and a film. The leaflet frame has a generally tubular shape defining a plurality of leaflet windows. The outer frame has a generally tubular shape. The leaflet frame is coaxially disposed at least partially within the outer frame. The leaflet frame and outer frame is coupled at least in part by a contiguous portion of the film. At least a portion of the contiguous portion of the film is contained between and coupling the leaflet frame and outer frame operable to prevent relative movement and contact therebetween. The film defines a leaflet extending from each of the leaflet windows.

  • Publication number: 20190091014
    Abstract: Aspects of the disclosure relate to prosthetic valves having a frame, a frame cover, and a leaflet construct. Some aspects are directed to a diametric taper for the prosthetic valve for achieving enhanced performance of the prosthetic valve under operational conditions, enhanced compressibility and delivery characteristics, and other additional or alternative advantages. Other aspects are directed toward unique assembly and attachment methods for securing leaflet constructs to support structures. Other aspects are directed toward features for interacting with transcatheter delivery systems. Still other aspects are directed to such apparatuses, systems, and methods for valve replacement, such as cardiac valve replacement.

  • Publication number: 20180353293
    Abstract: Described embodiments are directed toward prosthetic valves having a support structure and at least one leaflets. The leaflet comprises means for allowing fluid that is behind the leaflet to pass through to the front of the leaflet when the leaflet is not in the closed position. The prosthetic valve includes a leaflet moveable between an open position that permits antegrade flow through the prosthetic valve and a closed position that prevents regurgitant flow through the prosthetic valve, the leaflet having an aperture or gap, or a separation of portions of the leaflet to allow a flow or exchange of fluid between a front and back of the leaflet, when the leaflet is not in the closed position.

  • Publication number: 20180125646
    Abstract: Described embodiments are directed toward prosthetic heart valve leaflets of particular shapes that control bending character. In accordance with an embodiment, a prosthetic heart valve comprises a leaflet frame having a generally tubular shape with attached film. The leaflet frame defines a plurality of leaflet windows. The film defines at least one leaflet extending from each of the leaflet windows. Each leaflet attachment zone on the leaflet frame has substantially the shape of an isosceles trapezoid having two leaflet sides, a leaflet base and a leaflet free edge opposite the leaflet base. The two leaflet sides diverge from the leaflet base, wherein the leaflet base is substantially flat.
