ABSTRACT:
A plastic stent for a prosthetic trileaflet heart valve consisting of a cylindrical body portion terminating at one end in three apical, spaced commissure posts, and at the other end, in a skirt comprising three arcuate extensions, each extension being provided with an interrupted channel adjacent the outer edge thereof. An optional metal ring may be mounted over the skirt adjacent the body portion. A cloth cover is secured to the stent by stitching directly through the skirt in the area of reduced thickness resulting from the interrupted channel.
