Controlled Expression of Expandable Heart Valve

A method of implanting a prosthetic heart valve into a native heart valve annulus, the method comprising:

• delivering the prosthetic heart valve to a location at or adjacent the native heart valve annulus while the prosthetic heart valve is maintained in a collapsed condition within an overlying sheath of a delivery device, the prosthetic heart valve including a collapsible and expandable outer frame, a collapsible and expandable inner frame positioned radially inward of the outer frame and coupled to the outer frame, a prosthetic valve assembly coupled to, and positioned radially inward of, the inner frame, and a constraining band extending around a circumference of the inner frame;
• deploying an outflow end of the prosthetic heart valve from the delivery device;
• and
• deploying an inflow end of the prosthetic heart valve from the delivery device after deploying the outflow end of the prosthetic heart valve, so that the inner frame has a first diameter after deployment of the inflow end of the prosthetic heart valve;
• wherein the constraining band prevents the inner frame from expanding to a second diameter larger than the first diameter during deployment of the outflow end of the prosthetic heart valve.
