Abstract
A prosthetic heart valve includes a support frame and a plurality of leaflets disposed inside the support frame. The support frame extends between an inflow end and an outflow end and includes a leaflet frame and a plurality of positioning members coupled to the leaflet frame. The leaflet frame has an undulating shape at the outflow end of the support frame and includes a plurality of commissure regions spaced apart from each other. The positioning members are disposed between the commissure regions of the leaflet frame and extend radially outwardly relative to the leaflet frame. The positioning members are configured to contact native tissue and anchor the support frame relative to the native tissue. The leaflets are coupled to the commissure regions of the leaflet frame. The leaflets are configured to allow flow in a first direction and to substantially block flow in an opposite direction.
