Mitral and tricuspid annuloplasty rings
First Claim
1. A mitral annuloplasty ring, comprising:
- an inner core and an outer band located around the outside of the inner core for anchoring the ring to a mitral annulus;
the ring having an anterior region and a posterior region opposite the anterior region, and two side regions between the anterior and posterior regions, the ring having a vertical dimension extending between the anterior region and posterior region and a transverse dimension extending between the side regions, wherein the transverse dimension is greater than the vertical dimension and the ring is saddle-shaped and describes a three-dimensional path that gradually curves up at the anterior and posterior regions and down at the side regions; and
wherein a width dimension of the outer band as seen in cross-section through the ring is greater in the posterior region of the ring than in the anterior region.

Abstract
A mitral annuloplasty ring with an inner core and an outer band located therearound is disclosed. The ring has an anterior region, a posterior region opposite the anterior region, and two side regions therebetween. A cross-sectional width dimension of the outer band is greater in the posterior region of the ring than in the anterior region. A cross-sectional width dimension of a semi-flexible core is thinner in the anterior and posterior regions than in the side regions so that the mitral ring is more rigid in the anterior-posterior direction. A tricuspid annuloplasty ring of the invention has an inner core and an outer band located therearound. The inner core has an anterior region separated across a gap from a septal region, and a posterior region. A cross-sectional width dimension of the outer band is greater in the septal region than either the anterior or posterior regions.

14. A tricuspid annuloplasty ring, comprising:
-
an inner core and an outer band located around the outside of the inner core for anchoring the ring to a tricuspid annulus; the inner core having an anterior region separated across a gap from a septal region, and a posterior region, wherein a width dimension of the outer band as seen in cross-section through the ring is greater in the septal region than either the anterior region or posterior region; and wherein the inner core defines a spiral shape that mimics the shape of the healthy tricuspid annulus shape, with the anterior region and anterior half of the posterior regions lying in the same plane, and the posterior half of the posterior region and the septal region sloping down from the plane. - View Dependent Claims (15, 16)
