摘要： A prosthetic heart valve includes a collapsible and expandable stent extending in a longitudinal direction between an inflow end and an outflow end, the stent including a plurality of struts defining a plurality of cells, and a plurality of commissure attachment features disposed on the stent, each commissure attachment feature having a first end, a second end opposite the first end, and at least two bodies connected via one or more suspension struts, each of the at least two bodies having at least one eyelet.

摘要： 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.

摘要： A prosthetic heart valve includes a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end. The stent is formed of a plurality of struts. A cuff is coupled to the stent. The cuff has one or more features configured to reduce abrasion and/or perivalvular leakage.

摘要： A prosthetic heart valve includes a stent having a collapsed condition and an expanded condition, the stent having a proximal end, a distal end and a plurality of commissure features. The heart valve further includes a valve assembly secured to the stent, the valve assembly including a cuff and a plurality of leaflets, each of the leaflets having a free edge having a first end and a second end, and a second edge secured to the cuff, the second edge having a first end, a second end, a first folded portion adjacent the first end, a second folded portion adjacent the second end, and an unfolded portion between the first and second folded portions. The first and second folded portions couple the leaflet to ones of the commissure features.
