This is a non-surgical tricuspid annuloplasty to treat functional tricuspid valve regurgitation, meaning regurgitation with intact valve leaflets. The device is delivered using novel catheter techniques into the pericardial space and positioned along the atrioventricular groove. A compression member is positioned along the tricuspid annular free wall and tension applied through a variably-applied tension element. In the best embodiment, the compression member has an M shaped portion with at least two inflection points between the segments of difference curvatures.
