Abstract
An annuloplasty ring (for use as a heart valve prosthesis) has a non-planar shape and different lateral flexibilities at different points as one proceeds annularly around the ring. These different lateral flexibilities may be achieved in different ways such as by changing the material and/or cross-sectional size, shape, or other stiffness-imparting characteristics of the cross section.
