Abstract
Annuloplasty rings reduce or eliminate tricuspid regurgitation and/or tricuspid annulus dilation. An adjustable annuloplasty device includes a ring body having a first free end and a second free end. The ring body includes a shape memory material to provide a shape change to the adjustable annuloplasty device upon activation. The ring body includes a first segment including the first free end and following a curved path corresponding to an anterior leaflet region of a tricuspid annulus, a second segment following a curved path corresponding to a posterior leaflet region of the tricuspid annulus, and a third segment including the second free end and at least partially following a linear path corresponding to a portion of a septal leaflet region of the tricuspid annulus. Activation of the shape memory material changes a dimension of the adjustable annuloplasty device.
