Abstract
An expandable annuloplasty ring which may either expand spontaneously, in situ, as the patient grows or be expanded by surgical intervention by balloon dilatation. The distensible annuloplasty ring of the invention may be usable in pediatric patients whose growth, subsequent to surgical implantation of the ring, will necessitate subsequent enlargement of the ring to accommodate growth of the annulus. The ring may include a solid core of non-elastic material which plastically retains its shape upon natural expansion of the annulus, or after surgical expansion. A discontinuity may be positioned along the anterior side of the ring or around the posterior side.
