Abstract:
1. A prosthetic heart valve, comprising: a stent having a collapsed condition and an expanded condition, the stent extending in a longitudinal direction between a proximal end and a distal end and including a plurality of cells arranged in annular rows around a circumference of the stent, each cell being formed by a plurality of struts so that the cells have substantially a diamond shape with a first end pointing toward the distal end of the stent and a second end pointing toward the proximal end of the stent, the plurality of cells including subsets of cells in which the first end of one cell is aligned in the longitudinal direction with the second end of another cell, the plurality of struts including ancons at which multiple struts merge; a plurality of commissure features disposed on the stent, each of the commissure features being disposed in the longitudinal direction between the first end of the one cell and the second end of the another cell so that the commissure feature is aligned in the longitudinal direction with the first end of the one cell and the second end of the another cell; and a valve assembly secured to the stent and including a cuff and a plurality of leaflets disposed between the plurality of commissure features and the proximal end of the stent, each of the plurality of leaflets being sutured only to the cuff between respective pairs of the commissure features with a repeating pattern of sutures, the pattern of sutures including a descending seam at a spaced distance from one group of the plurality of struts, an ascending seam at the spaced distance from another group of the plurality of struts, and a vertex between the descending seam and the ascending seam, the pattern of sutures passing between two pairs of adjacent ancons near the vertex.
