Percutaneous annuloplasty system with anterior-posterior adjustment

An adjustable annuloplasty ring for percutaneous, transcatheter heart valve repair, the annuloplasty ring comprising:

• a body member comprising at least three sections, wherein the body member is transitionable from an elongate insertion geometry to an annular operable geometry,
• a plurality of anchors percutaneously deployable from the body member in the annular operable geometry to engage the annulus of a target valve;
• and
• at least two biasing elements, wherein each biasing element is separated from any other biasing element by at least one of the at least three sections wherein the at least two biasing elements are configured to expand or contract independently of each other, and
• wherein the two or more biasing elements bias the annuloplasty ring in the operable geometry toward a contracted state such that expansion of the annuloplasty ring to an expanded state stores a potential energy in the two or more biasing elements,
• wherein the at least two biasing elements each comprise an integral biasing portion of the body member,
• wherein the integral biasing portion of the body member comprises a spiral cut in a portion of the body member to form a spiral shape in the body member that is expandable to the expanded state and that is biased toward the contracted state.
