Abstract
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 including a plurality of struts. A plurality of commissure features is disposed on the stent and coupled to selected ones of the struts, each commissure feature including a body having a proximal end and a distal end, and at least one eyelet in the body. The heart valve further includes a collapsible and expandable valve assembly including a plurality of leaflets. At least one leaflet is connected to the at least one eyelet and to at least one of the selected ones of the struts via a suture pattern.

A prosthetic heart valve, comprising:
- 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 including a plurality of struts;
- a plurality of commissure features disposed on the stent and coupled to selected ones of the struts, each commissure feature including a body having a proximal end and a distal end, and at least one eyelet in the body;
- a collapsible and expandable valve assembly, including a plurality of leaflets, at least one of the leaflets being connected to the at least one eyelet and to at least one of the selected ones of the struts via a suture pattern.
A method of assembling a prosthetic heart valve, comprising:
- providing 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 including a plurality of struts and a plurality of commissure features disposed on the stent and coupled to selected ones of the struts, each commissure feature including a body having a proximal end and a distal end, and at least one eyelet in the body;
- coupling a collapsible and expandable valve assembly to the stent, the valve assembly including a plurality of leaflets, and the coupling step including connecting at least one of the leaflets to the at least one eyelet and to at least one of the selected ones of the struts via a suture pattern.
