Abstract
A prosthetic heart valve includes an expandable stent and a leaflet assembly coupled to the expandable stent. The expandable stent is radially expandable from a first size for intraluminal delivery through a body passageway to a second size for implantation of the prosthetic heart valve in the body passageway. The leaflet assembly includes leaflets movable between an open position permitting flow past the expanded stent and a closed position substantially restricting flow past the expanded stent. Each of the leaflets is coaptable with each of the other leaflets in the closed position to define a coaptation region of about 15 percent to about 35 percent of the overall height of each of the plurality of leaflets.
