Abstract
A prosthetic heart valve, comprising (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) a water-absorbing polymer coupled to the cuff.
