Commissure attachment feature for prosthetic heart valve
First Claim
1. 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 including at least one eyelet, the body being coupled to upper struts near the aortic section and lower struts near the annulus section; and
a collapsible and expandable valve assembly including a plurality of leaflets and a cuff;
a first suture for coupling the cuff to the stent;
a second suture for coupling each of the plurality of leaflets to portions of the cuff; and
a group of third sutures, each of the third sutures being configured to couple at least one of the leaflets to the at least one eyelet and to at least one selected strut from the upper struts and the lower struts via a suture pattern.

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.

14. 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, each commissure feature including a body having a proximal end adjacent the annulus section and a distal end adjacent the aortic section, and at least one eyelet in the body, the body being coupled to the upper struts near the distal end of the body and to lower struts near the proximal end; and coupling a cuff to the stent via a first suture; coupling each of a plurality of leaflets to portions of the cuff via a second suture; and coupling each of the leaflets to the at least one eyelet and to at least one selected strut from the upper struts and the lower struts via a third suture. - View Dependent Claims (15, 16, 17, 18, 19, 20)
