Abstract
An expandable annuloplasty ring which may be enlarged in situ comprising essentially uniform ring distension in the circumferential direction. The expandable annuloplasty ring is usable in pediatric patients whose growth necessitates enlargement of the ring by application of shape-memory material by way of heat activation or other non-mechanical means to accommodate growth of the annulus. The invention includes a non-contact method for post-implantation enlargement of the annuloplasty ring via a magnetic circuit or an external heat source.
