Abstract
A prosthetic heart valve includes (a) a stent body including a generally tubular annulus region having a tubular wall and a proximal-to-distal axis, the stent body having a radially expanded condition when the stent body is implanted, (b one or more prosthetic valve elements mounted to the stent body and operative to allow blood flow in a distal direction through the annulus region but to substantially block blood flow in a proximal direction through the annulus region, (c) a cuff coupled to the stent body, and (d) one or more biasing elements connected to the stent body and to the cuff, the biasing elements being adapted to bias at least a portion of the cuff outwardly with respect to the stent body.
