Abstract:
1. An adjustable annuloplasty device, comprising: a ring body having a first free end and a second free end, the ring body comprising a shape memory material to provide a shape change to the adjustable annuloplasty device in response to activation energy, the ring body including: 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, wherein application of the activation energy to the shape memory material reduces a length of the first segment, reduces a length of the second segment, and changes a dimension of the adjustable annuloplasty device, wherein the application of the activation energy reduces the length of the first segment more than it reduces the length of the second segment, and wherein the application of the activation energy reduces a distance between the first free end and an axis corresponding to the linear path of the third segment.
