Abstract
A frame assembly includes a valve body, a plurality of arms that each extend radially outward from the valve body to a respective arm-tip, and a plurality of ventricular legs that are coupled to the valve body and that extend radially outward from the valve body and toward the plurality of arms. A liner lines the lumen. Prosthetic leaflets are attached to the liner within the lumen. A first sheet of flexible material is attached to the plurality of arms. A second sheet of flexible material is attached to the first sheet and extends radially inwards and downstream, and is attached to the valve body. The first sheet, the second sheet, and the liner define an inflatable pouch therebetween. The apparatus defines a plurality of windows from the lumen into the pouch.
