1. A valve prosthesis for implantation in an aortic annulus, the valve prosthesis comprising:

  • a collapsible, elastic valve member comprised of physiologically acceptable material, an elastic stent member in which said valve member is mounted, said stent member having internal and external surfaces, and a support coupled to the valve member and positioned between the valve member and the stent member, wherein said stent member forms a continuous surface and comprises strut members that provide a structure sufficiently rigid to prevent eversion, wherein the support extends from the internal surface of the stent member to the external surface of the stent member, and wherein the stent member has sufficient radial and longitudinal rigidity to withstand the radial force necessary for implantation, to resist aortic recoil forces, and to provide long-term support to the valve structure.
