The method of claim 3, wherein the component includes a pulley. 5. The method of claim 3, wherein the component includes a screw. 6. The method of claim 1, wherein the adjustment mechanism is mounted on the annuloplasty ring and the elongate members all engage the adjustment mechanism and are tensioned via adjustment thereof. 7. A method of treating an atrioventricular heart valve, comprising: stopping the patient's heart and providing access to a heart chamber;implanting a device within the heart chamber, wherein the device includes an annuloplasty ring, a plurality of elongate members that extend through internal channels extending around at least a portion of the annuloplasty ring, wherein an end of a first elongate member is configured to be secured to a papillary muscle and a second elongate member is configured to alter a diameter of the annuloplasty ring, and an adjustment mechanism configured to increase tension in the plurality of elongate members, wherein the adjustment mechanism comprises a rotatable member around which the first elongate member is coiled so that rotation of the rotatable member alternately tensions or relaxes the first elongate member;securing the annuloplasty ring to an annulus of the atrioventricular heart valve;securing the first elongate member to a papillary muscle within the heart chamber;closing the implant site and restarting the patient's heart; andactuating the adjustment mechanism to alter a diameter of the annuloplasty ring and reduce the distance between the annuloplasty ring and the papillary muscle to which the first elongate member is secured. 8. The method of claim 7, wherein actuating the adjustment mechanism simultaneously alters a diameter of the annuloplasty ring and reduces the distance between the annuloplasty ring and the papillary muscle to which the first elongate member is secured. 9. The method of claim 8, wherein the adjustment mechanism is mounted on the annuloplasty ring and the first and second elongate members both engage the adjustment mechanism and are tensioned thereby. 10. The method of claim 9, wherein the second elongate member is also coiled around the rotatable member so that rotation of the rotatable member alternately tensions or relaxes both first and second elongate members. 11. The method of claim 7, wherein the annuloplasty ring include a stiffening member therein, and wherein the second elongate member extends through the internal channels around at least a portion of the annuloplasty ring and attaches to one end of the stiffening member such that tension in the second elongate member alters a diameter of the annuloplasty ring. 12. The method of claim 7, wherein the step of actuating the adjustment mechanism occurs after a step of closing up the implant site and restarting the patient's heart, and further including the step of monitoring a function of the heart valve while actuating the adjustment mechanism. 13. A method of treating an atrioventricular heart valve, comprising: stopping the patient's heart and providing access to a heart chamber;implanting a device within the heart chamber, wherein the device includes an annuloplasty ring, a first pair of elongate members that extend through internal channels in the annuloplasty ring, exit through openings in a lower portion of the annuloplasty ring, and are each configured to be secured to a papillary muscle, the device further including a second pair of elongate members that extend through internal channels in the annuloplasty ring and are configured to alter a diameter of the annuloplasty ring, and an adjustment mechanism mounted on the annuloplasty ring and which engages each of the elongate members, wherein the first pair of elongate members extend in opposite directions from the adjustment mechanism, and the second pair of elongate members extend in opposite directions from the adjustment mechanism, wherein the adjustment mechanism comprises a rotatable member around which the first pair of elongate members is coiled so that rotation of the rotatable member alternately tensions or relaxes the first pair of elongate members;securing the annuloplasty ring to an annulus of the atrioventricular heart valve;securing the first pair of elongate members to different papillary muscles within the heart chamber;closing the implant site and restarting the patient's heart; andactuating the adjustment mechanism to increase tension in both the first and second pairs of elongate members to alter a diameter of the annuloplasty ring and reduce the distance between the annuloplasty ring and the papillary muscles. 14.
