Annuloplasty ring and method for producing same

Abstract

The present invention relates to an annuloplasty ring having a core part 10 and an outer layer 20. The core part 10 is curved such that a band-shaped plate member made of a spring material defines an opening part in a shape along a mitral valve annulus and presents a C-shape. The outer layer 20 is a layer made of a polymer material and covering a surface of the aforementioned core part 10. A longitudinal axis 10a of the cross section of the aforementioned band-shaped plate member when the core part is cut along a flat plane containing the central axis Z passing through the opening part in the blood flow direction F is inclined with respect to the central axis Z, and the inclination is such that the diameter of the opening part decreases as the central axis Z moves in the blood flow direction F.
