A method of assembling a prosthetic heart valve includes providing a collapsible and expandable stent having an annulus section and an aortic section. The annulus section has a first diameter in a relaxed condition and a second diameter less than the first diameter in a collapsed condition. A constraint is applied to the stent to constrain the annulus section to a predetermined diameter between the first and second diameters. Applying a cuff and/or a plurality of leaflets to the stent in the constrained condition enables less material to be used. The resultant prosthetic valve is therefore able to be collapsed to a smaller diameter for introduction into a patient.

An assembly for loading a self-expanding prosthetic heart valve into a delivery device, includes a compression member having a longitudinal axis, a first open end with a first diameter, a second open end with a second diameter less than the first diameter, and a wall decreasing in diameter from the first open end to the second open end, a support member having a longitudinal axis, a base and a recess extending along the longitudinal axis and adapted to receive an end of the valve, the support member and the compression member being movable between an initial position and an operative position, and a substantially tubular restrainer disposed within the support member and, in the operative position of the compression member and the support member, defining a passageway for accepting a portion of the delivery device and leaflets of the valve when the valve is assembled on the support member.
