ABSTRACT:
A sewing ring for a heart valve prosthesis to allow the valve to be sutured into operative position in association with a region of a human heart from which a defective valve has been excised. The generally cylindrical exterior surface of a valve body of circular cross-section is provided with either an encircling groove or a protruding annular band. To interconnect with such groove or band, a metal split sleeve is provided which has either a radially inward directed projection or an annular cavity for mating, respectively, with the groove or band of the valve body. A tubular fabric sleeve from which a sewing cuff is constructed is first fitted about the valve body, and a central portion of such fabric sleeve is sandwiched between the split sleeve and the valve body so that it is entrapped and preferably compressed between the interconnecting elements. A continuous locking ring, e.g. a rigid tubular metal sleeve, is frictionally fit about the exterior surface of the split sleeve to lock the fabric sleeve in place, which is then fashioned into a sewing cuff. The components may be sized so that the cuff is rotatable on the valve body or non-rotatable, as desired.
