Abstract

See full text

An annuloplasty repair segment for heart valve annulus repair and a method for forming. A multi-stranded cable replaces solid core wire for both the tricuspid and mitral valves which allows for greater deployment flexibility for minimally-invasive surgical (MIS) implant, while still maintaining the required strength and similar tensile properties of solid-core wire. The particular shape of the annuloplasty ring is fixed using a heat setting process including heating the flexible core member to a temperature higher than 500° C. and holding it in a desired heat-set saddle shape for a period of time. The core is then rapidly cooled to impart physical properties such that the flexible core member can be straightened, during implantation, to fit through a tubular access device and regain the heat-set saddle shape after exiting the access device and, when attached to the native heart valve, the flexible core member is strong enough to remodel the native heart valve.
