TRICUSPID RING
First Claim
1. A tricuspid ring for use in an annuloplasty procedure, comprising:
- an inner core comprising a plurality of layers stacked along the Z axis;
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.

24. A tricuspid ring for use in an annuloplasty procedure, comprising:
-
an inner core having a substantially rectangular cross section defined by a thickness and a width; an elastomeric interface at least partially covering the inner core; and a biocompatible flexible layer at least partially covering the elastomeric interface, wherein the inner core is configured such that its width and thickness result in a stiffness in the XY plane that is approximately 25 times the stiffness along the Z axis or greater. - View Dependent Claims (25, 26)
