A valve prosthesis, comprising:
- a support frame radially expandable between a compact condition and an expanded condition, said support frame having an outer surface and defining a central orifice about an axis along an inflow-outflow direction;
- a plurality of flexible leaflets attached to the support frame to provide a one-way valve in the orifice when the support frame is in its expanded condition;
- and
- at least one valve clasper movably attached to said support frame such that said at least one valve clasper is movable relative to said support frame along said, axis between a nesting position with the outer surface of the support frame and an engagement position with the valve annulus wherein said at least one valve clasper is physically separated from said support frame.
