Claim 10:
11. An asymmetrical mitral annuloplasty band adapted for implant against a mitral valve annulus, the annulus having a posterior aspect to which a posterior leaflet attaches and an anterior aspect to which an anterior leaflet attaches, the annulus defining a D- or kidney-shape looking at an inflow side thereof with the anterior aspect being straighter than the more rounded posterior aspect and a minor axis intersecting and extending across the annulus between mid-points on the anterior and posterior aspects being shorter than a major axis perpendicular thereto intersecting and extending across the mitral valve annulus, and the annulus defining a saddle shape where the annulus rises up toward the left atrium at mid-points of both the anterior aspect and the posterior aspect, the band comprising:
an inner elongated discontinuous rigid or semi-rigid core surrounded by a suture-permeable interface, the core defining an asymmetric shape of the band as viewed in top plan view when implanted that generally conforms to a portion of the shape of the mitral annulus extending around the entire posterior aspect and including an upward bow corresponding with the rise in the posterior aspect and defining a reference point at a mid-point of the upward bow, wherein the band extends clockwise along a first span from the reference point to a first free end and extends farther counterclockwise along a second span to a second free end, the band defining a gap between the first and second free ends, wherein the band has a partial saddle shape with a first high point at the reference point, two low points located approximately at an intersections of the band with the major axis, and a second high point at the second free end.
