Abstract
The distensible annuloplasy ring which may be enlarged, in situ, by application of dilatory pressure by way of a balloon or other dilating apparatus. The distensible annuloplasy ring of the invention is 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 invention includes a transluminal and/or transeptal method for post-implantation enlargement of the annuloplasty ring via catheter.
