1. A prosthetic valve assembly comprising:
- a support structure having an inlet end and an outlet end, wherein the support structure includes a plurality of longitudinally rigid support beams, said support structure configured to be radially collapsible and expandable;
a valve comprising a pliant material having an inlet and an outlet, wherein said pliant material has a plurality of tabs at said outlet, and wherein said plurality of tabs are attached to said support beams at said outlet end of said support structure; and
a cuff operably attached to an outer surface of said support structure at said inlet of said support structure, wherein said cuff is disposed radially outside of said support beams, wherein said cuff has a radial lip configured to facilitate positioning and securing said valve assembly in a body lumen, wherein said cuff comprises a first cylindrical portion and a second cylindrical portion, said first cylindrical portion having greater thickness than said second cylindrical portion, wherein the first cylindrical portion is disposed downstream of the second cylindrical portion, and wherein said radial lip is defined by an interface of said first cylindrical portion and said second cylindrical portion.
