Abstract

1293014 Cardiac valve implant RHONEPOULENC SA 3 Feb 1970 [4 Feb 1969 19 Dec 1969] 5171/70 Heading A5R A cardiac valve support adapted to fit against the cusps of the human heart comprises an annular or part annular member composed of an asymmetric channel-shaped, rigid frame 3, Fig. 2, preferably of stainless steel with a cord 6 held in place in the groove of the member by a filament 8, preferably of P.T.F.E., within the cord, and a woven, textile sheath 7, preferably also of P.T.F.E., enclosing said frame and cord. An embodiment, Fig. 1, adapted to fit around the cusps of the mitral valve is in the form of a ring 1 with a substantially straight part 2. An alternative embodiment, Fig. 5 (not shown) is in the form of a broken ring, the said straight part being omitted. In use the member is fixed around the cusps of the valve in question by means of stitches placed through the cord 6 and the natural heart tissue. In alternative embodiments the member may be of circular or oval configuration or in a trifoliate form of three arcuate segments with intermediate cusps and ethyleneglycol polyterephthalate may be used instead of P.T.F.E. as the inert material.
