Abstract

A cardiac valve (40) comprises a plurality of flexible membranes (42, 44), each having an edge joined by sutures (58, 60) to an edge of another of the membranes to form an unsupported closed body. The body has an oval end .portion (46, 48) and forms a plurality of flexible flap portions (51, 53) extending Pram the end portions, the flap portions of unequal size being formed by sub-stantially parabolic scallops. The sutures (58, 60) extent from the oval end (46, 48) to the apical ends (54, 56) and provide streng-thening for the valve.
