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.
