Abstract
A replacement heart valve device is disclosed. In some embodiments, the device includes a frame coupled to one or more leaflets that are moveable between open and closed configurations.

In some embodiments, the device may be geometrically accommodating to adapt to different vasculature shapes and sizes and/or to be able to change size while implanted within a growing patient.
Claims14
A valve replacement device, comprising:
- a valve frame comprising first and second U-shaped frame sections connected at one end by a pair of commissures, the valve frame defining an opening for the passage of fluid, the first and second frame sections each having first and second arms, the valve frame being expandable to permit an increase in a diameter of the opening over a diameter size range of the opening;
- a valve leaflet coupled to the valve frame, the valve leaflet having an open configuration in which the opening is exposed, and a closed configuration in which the valve leaflet at least partially covers the opening, wherein the valve leaflet is configured to be moveable between the open and closed configurations over the diameter size range of the opening;
- and
- a sleeve coupled to the valve frame, the sleeve having a first expandable direction orientated to permit the increase in the diameter of the opening of the valve frame,
- wherein the sleeve further comprises a film, wherein the film is configured to minimize native tissue ingrowth into the sleeve.
