Myocardial implant load sharing device and methods to promote LV function

The devices and methods described herein may be used to restore left ventricular function to address mitral valve regurgitation. One variation of an implant comprises a plurality of tethered anchors and a plurality of force-distribution members slidably disposed on the tether between the anchors. One or more of the force-distribution members can comprise a bioabsorbable material. Methods comprise deploying the implant to cardiac tissue, cinching the implant to its hard stop (e.g., where further cinching does not cause further tissue tightening), providing a pre-selected amount of slack to the implant after it has been cinched to its hard stop configuration, and securing a lock member on the tether. Also disclosed herein are lock member deployment catheters that provide a pre-selected amount of tether slack as it secures a lock member on the tether.
