An adjustable annuloplasty ring comprising: a body member that is transitionable from an elongate insertion geometry to an annular operable geometry, the elongate insertion geometry to allow percutaneous passage of the annuloplasty ring, via a catheter, into a heart of a patient, and the annular operable geometry having an expanded state to conform to an annulus of a target valve of the heart and a contracted state to reduce a diameter of the annulus of the target valve; a plurality of anchors percutaneously deployable from the body member in the annular operable geometry to engage the annulus of the target valve; and a biasing element disposed between a first region and a second region of the body member, the biasing element configured to be expanded to increase an anterior-posterior distance of the annuloplasty ring in the annular operable geometry to the expanded state in abutment with the annulus of the target valve, such that subsequent deployment of the plurality of anchors fastens the body member to the annulus of the target valve, wherein the biasing element biases the annuloplasty ring in the operable geometry toward the contracted state such that expansion of the annuloplasty ring to the expanded state stores potential energy in the biasing element and releasing the biasing element releases the potential energy to force movement of the first region of the body member toward the second region of the body member to decrease the anterior-posterior distance of the annuloplasty ring to the contracted state and thereby decrease an anterior-posterior distance of the target valve to improve leaflet coaptation of the target valve and reduce regurgitation through the target valve; characterized in that, the body member is formed from an elongate hollow member; and further wherein the annuloplasty ring comprises a ring closure lock adapted to secure two open ends of the annuloplasty ring to form a closed ring of the operable geometry;; and wherein the biasing element comprises 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. a body member that is transitionable from an elongate insertion geometry to an annular operable geometry, the elongate insertion geometry to allow percutaneous passage of the annuloplasty ring, via a catheter, into a heart of a patient, and the annular operable geometry having an expanded state to conform to an annulus of a target valve of the heart and a contracted state to reduce a diameter of the annulus of the target valve; a plurality of anchors percutaneously deployable from the body member in the annular operable geometry to engage the annulus of the target valve; and a biasing element disposed between a first region and a second region of the body member, the biasing element configured to be expanded to increase an anterior-posterior distance of the annuloplasty ring in the annular operable geometry to the expanded state in abutment with the annulus of the target valve, such that subsequent deployment of the plurality of anchors fastens the body member to the annulus of the target valve, wherein the biasing element biases the annuloplasty ring in the operable geometry toward the contracted state such that expansion of the annuloplasty ring to the expanded state stores potential energy in the biasing element and releasing the biasing element releases the potential energy to force movement of the first region of the body member toward the second region of the body member to decrease the anterior-posterior distance of the annuloplasty ring to the contracted state and thereby decrease an anterior-posterior distance of the target valve to improve leaflet coaptation of the target valve and reduce regurgitation through the target valve; characterized in that, the body member is formed from an elongate hollow member; and further wherein the annuloplasty ring comprises a ring closure lock adapted to secure two open ends of the annuloplasty ring to form a closed ring of the operable geometry;; and wherein the biasing element comprises 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.
