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.
