Valve assembly for crimp profile

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 constr...

More Information
Summary: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.
