Abstract:
1. A method of implanting a prosthetic heart valve in a patient, comprising: providing a two-part heart valve, each part being expandable from a compressed state, a first part comprising an external scaffolding frame expandable into a substantially cylindrical shape having an interior surface defining an opening, and a second part comprising a collapsible valvular structure fastened within an internal frame, the valvular structure comprising valve leaflets formed of a biological material; delivering the external scaffolding frame in its compressed state to an annulus of a native semi-lunar heart valve in a human heart; expanding the external scaffolding frame into an expanded state to secure the external scaffolding frame within the annulus of the native semi-lunar heart valve; delivering the second part to within the opening of the expanded external scaffolding frame; and expanding the internal frame against the interior surface of the external scaffolding frame such that the internal frame is fixed to the external scaffolding frame.
