19. A method of percutaneous transcatheter repair of a heart valve, the method comprising:

  • positioning a catheter percutaneously into a heart;

    inserting an adjustable annuloplasty ring configured in an elongate insertion geometry through the catheter and into the heart;

    transitioning the annuloplasty ring from the elongate insertion geometry to an annular operable geometry;

    actuating an expansion tool to expand the annuloplasty ring in the annular operable geometry to an expanded state, including expanding a biasing element of the annuloplasty ring, and thereby increase an anterior-posterior distance of the annuloplasty ring;

    positioning the annuloplasty ring in abutment with an annulus of a target valve of the heart;

    deploying a plurality of anchors of the annuloplasty ring to engage the annulus of the target valve to fasten the annuloplasty ring to the annulus; and

    releasing the expansion tool to release the biasing element of the annuloplasty ring and effectuate transition of the annuloplasty ring in the annular operable geometry from the expanded state to a contracted state to decrease the anterior-posterior distance of the annuloplasty ring 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.
