Abstract
Abstract The present invention includes a prosthetic heart valve having a stent and a piece of biocompatible material. The stent includes an inflow ring and a plurality of posts, each post extending from the ring to a post tip. The piece of material extends over the stent and substantially conforms to a profile of the stent. The piece of material includes a portion which extends adjacent a post tip. A clip is provided which has a shape generally conforming to the post tip to thereby clamp the portion of the piece of material to the post tip.
