    Abstract: A prosthetic heart valve for replacing a native valve includes a stent, a valve assembly, and a radiopaque element. The stent has a plurality of commissure attachment features. The valve assembly includes a plurality of leaflets and first and second cuffs. The first cuff has a proximal edge relatively close to the inflow end of the stent. The second cuff may be annularly disposed about the stent radially outward of the first cuff and radially outward of the stent. The proximal edge of the first cuff is coupled to the proximal edge of the second cuff substantially continuously along a circumference of the inflow end of the stent so that a pocket is formed between the first cuff and the second cuff. The radiopaque element is disposed within the pocket and aligned in a longitudinal direction of the stent with at least one of the plurality of commissure attachment features.

    Abstract: A prosthetic heart valve may include a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end, and a plurality of cells connected to one another in annular rows around the stent, a cuff attached to the stent, and a sealing member attached to the cuff and extending from a proximal end of the cuff to a free edge. The sealing member may be movable between an extended condition in which the free edge is located proximally of the proximal end of the stent, and an inverted condition in which the free edge is located distally of the proximal end of the stent and a first surface of the sealing member confronts an outward-facing surface of the cuff. Various mechanisms for moving the sealing member are also described.

    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.
