Patent ID: 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.
