Abstract
A suture ring including a continuous compression ring formed of a ductile, electrically conductive material and a layer of fabric secured around the compression ring. The compression ring is dimensioned slightly larger than the circumferential surface of a heart valve upon which it is to be secured, so that the suture ring can be slipped over the heart valve to a position adjacent the circumferential surface without radial expansion of the compression ring. The compression ring is deformed inwardly by electromagnetic forming to securely clamp the heart valve while permitting relative rotation between the suture ring and heart valve.
