<p>An annuloplasty ring prosthesis has a flexible, annular body including one or more defined lengths (16,30), which are more rigid than the remainder of the body. The flexible body increases in flexibility about its circumference in a direction away from the, or each rigid, defined length and is formed from a plurality of individual wire elements. The elements may be wire strands (14,24) secured in a bundle, positioned in respective lumens (26) of a multiple lumen enclosure (28), or may be layers (38) of one or more wire bands wrapped on one another. <IMAGE></p> |
