Abstract
A prosthesis for an inadequate or diseased heart valve, the prosthesis being formed of a porous fabric comprising multifilament synthetic yarns supported on a plural-lobed frame. The frame has generally parallel legs each comprising a pair of rod portions. The fabric is inserted between the rod portions of the legs to form flexible leaflets. Each leaflet consists essentially of a textile of filaments having a substantial number of open interstitial spaces in the range of 20 to 40 microns evenly distributed throughout the fabric. The resulting composite structures are free of thrombogenic complications.
