Abstract
Prosthetic valves and their component parts are described, as are prosthetic valve delivery devices and methods for their use. The prosthetic valves are particularly adapted for use in percutaneous aortic valve replacement procedures. The delivery devices may be adapted for use in minimally invasive or endovascular surgical procedures.

31. A medical device, comprising:
an expandable support structure comprising a plurality of panels with hinges between the panels, the expandable support structure having an inner lumen, wherein each panel surface includes at least one longitudinal depression, wherein the inner surface of the longitudinal depressions are relatively more adjacent to each other in the center of the expandable support structure when said expandable support structure is in a collapsed state. - View Dependent Claims (32)
-
33. A medical device, comprising:
-
an expandable support structure comprising a plurality of panels, wherein each panel includes a plurality of apertures, the density of the apertures in each panel forming a gradient where the density of apertures proximal to the lower periphery of the panel is greater than the density of apertures proximal to the upper periphery of the panel.
