Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A constraint for assembling a prosthetic heart valve including a collapsible and expandable stent having an annulus section, the annulus section having a first annulus diameter in a relaxed condition and a second annulus diameter less than the first annulus diameter in a collapsed condition, the constraint comprising: a cylindrical body having a proximal opening, a distal opening, and a lumen defined between the proximal opening and the distal opening and sized to constrain the annulus section to a predetermined annulus diameter between the first annulus diameter and the second annulus diameter, the body further comprising at least one window configured and arranged to permit assembly of the prosthetic heart valve therethrough. 2. The constraint of claim 1 , wherein the constraint further comprises a cone portion at the distal opening. 3. The constraint of claim 1 , wherein the constraint comprises three rings.
