Abstract
An implantable prosthetic valve having a stentless support structure. The valve has a tubular annular support structure with a first inflatable ring at a proximal end, a second inflatable ring at a distal end, and an inflatable intermediate support in between the first and second inflatable rings. There is at least one moveable occluder that controls the flow of blood through the tubular support structure. The tubular support structure can be filled with inflation media in the first inflatable ring, the second inflatable ring and inflatable intermediate support structure to convert the tubular support structure from a collapsed configuration to a patent tubular configuration.
