Abstract

An annuloplasty implant is disclosed comprising first and second support members having a coiled configuration in which the first and second support members are arranged as a coil, with two free ends,around a central axis, wherein, in said coiled configuration, said two free ends are displaced from each other with a peripheral off-set distance extending in a coil plane, said coil plane being substantially parallel to an annular periphery of said coil and perpendicular to said central axis, wherein the first and second support members and the respective free ends are configured to be arrangedon opposite sides of native heart valve leaflets of a heart valve. A method of implanting an annuloplasty implant at a target site in the heart is also disclosed.

Description

technical field [0001] The present invention relates generally to the field of replacement and repair of heart valves. More particularly, the present invention relates to annuloplasty implants, such as annuloplasty rings or helices, for positioning at the heart valve annulus. Background technique [0002] Diseased mitral and tricuspid valves often require replacement or repair. The mitral and tricuspid leaflets or supporting chordae may degenerate and weaken, or the annulus may dilate causing valve leakage. Mitral and tricuspid valve replacement and repair are often performed with the aid of an annuloplasty ring, used to reduce the diameter of the valve annulus, or to alter the geometry of the valve annulus in any other way, or during valve replacement or repair procedures The period aid serves as the overall support structure. [0003] A problem with prior art annuloplasty implants is to achieve reliable fixation at the annulus while at the same time accommodating the mo...
