Abstract
A stented valve suitable for use in body ducts. The valve includes an expandable support structure and an attached flexible membrane that changes shape when the valve opens and closes. The expandable support structure has the shape of a stent with a series of interconnected expandable unit cells and elongated support beams. When the valve is open, body fluid can flow around the membrane and pass through the gap between it and the inner stent surface. In one configuration, a set of two valves is combined with an intermediate inflatable balloon to create a cardiac assist pumping device. In another embodiment, valve closure can be achieved by remotely controlled valve leaflets actuation. A double aorta valve frame is used to accommodate shape and diameter variations of the annulus in an outer valve frame, while the inner valve frame has dimensions for optimized performance of the valve membrane.
