  • 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.

  • Patent number: 10376360
    Abstract: Described embodiments are directed toward centrally-opening leaflet prosthetic valve devices having two frames. A leaflet frame is coaxially disposed within a body frame. The body frame has a tubular shape defining a body frame lumen. The leaflet frame has an annular shape defining a plurality of U-shaped portions each defining a base and a plurality of posts. The leaflet frame is located coaxial with and at least substantially within the body frame lumen. A first film is coupled to the body frame and a second film is coupled to and extends across each of the U-shaped portions defining a leaflet having a free edge. At least one of the first film and second film couples the body frame to the leaflet frame. The leaflets are moveable between an open and closed position with the leaflet free edge of each of the leaflets abutting an adjacent leaflet free edge when in the closed position.

  • Publication number: 20180318070
    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.

  • Publication number: 20180303611
    Abstract: Described embodiments are directed toward centrally-opening leaflet support devices having a frame and one or more support leaflets coupled to the frame forming a hinge where coupled. The described support leaflets have one or more stiffer regions that facilitate the function of a support leaflet to decrease or prevent prolapse of a native valve leaflet. Methods of making and using such valve devices are also described amongst others.
