Abstract:
1. A prosthetic heart valve, comprising: (a) a stent body having a longitudinal axis and a generally tubular annulus region extending from a first position to a second position along the longitudinal axis; (b) one or more prosthetic valve elements mounted within the stent body and operative to allow flow in an antegrade direction through the annulus region but to substantially block flow in a retrograde direction through the annulus region; and (c) a cuff including one or more pockets outside of the annulus region and between the first position and the second position, each of the pockets having an outer wall, an opening facing in a first axial direction and a closed side facing in a second axial direction opposite to the first axial direction so that a flow of blood in the second axial direction will tend to force blood into the pocket.
