Tricuspid ring
First Claim
1. A tricuspid ring for use in an annuloplasty procedure, comprising:
- an inner core comprising a plurality of parallel and separate layers stacked along and defining a periphery around a Z axis, each of the layers comprising a coplanar structural portion and a lubricious shim portion, and wherein the structural portion of each layer is a separate and distinct element from the structural portions of the other layers, wherein at least one weld point couples the layers of the inner core together;
an elastomeric interface at least partially covering the inner core; and
a biocompatible flexible layer at least partially covering the elastomeric interface.

Abstract
A prosthetic tricuspid remodeling annuloplasty ring having two free ends can be configured to be stiff in the XY plane and relatively flexible along the Z axis. A tricuspid ring can be provided with a substantially elliptical shape in the XY plane, and a saddle shape in the Z direction. Disclosed tricuspid rings can include an inner core, an elastomeric interface, and an outer fabric covering. In some embodiments, the inner core can include a plurality of stacked layers of different materials. In some embodiments, the inner core can be formed of a single material and sized specifically to create a tricuspid ring that has a greater stiffness in the XY plane than along the Z axis.

13. An annuloplasty ring, comprising:
an inner core comprising a plurality of parallel and separate layers stacked along and defining a periphery around a Z axis, each of the layers having a structural portion that extends around the periphery a different distance than the structural portion in any adjacent layer such that the structural portion in adjacent layers partially overlap, and each layer having a coplanar shim portion that extends between adjacent structural portions where they do not overlap. - View Dependent Claims (14, 15, 16, 17, 18)

19. An annuloplasty ring, comprising:
an inner core comprising a plurality of parallel and separate layers stacked along and defining a periphery around a Z axis, each of the layers having a relatively rigid structural portion that extends around the periphery a first distance and a coplanar shim portion that extends around the periphery a second distance different than the first distance, wherein the ring is configured such that a gap exists between a first free end and a second free end, and in any one layer the structural portion extends from one of the first or second free end while the shim portion extends from the other of the first or second free end, and the end from which the structural portion extends alternates in sequential layers. - View Dependent Claims (20, 21, 22, 23, 24)
