1. An implantable apparatus for reshaping an annulus surrounding a heart valve, the apparatus comprising:

  • an implant body comprising a plurality of struts having a proximal end, a distal end, a central lumen extending therethrough and pairs of adjacent struts with each pair joining at an angle to form an apex, wherein the pairs of adjacent struts on the implant body join to form one or more apices on the proximal end and one or more apices on the distal end, the one or more apices on the distal end each having a series of holes configured to receive therethrough a corresponding anchor, the implant body configured to;

    compress to a first configuration during delivery into an atrium of a heart;

    expand to a second configuration larger than the first configuration, the second configuration for engaging tissue surrounding a heart valve; and

    contract to a third configuration smaller than the second configuration but larger than the first configuration, the third configuration having a width that is sufficiently small to reshape the annulus of the heart valve when implanted in the tissue surrounding the heart valve annulus; and

    a plurality of distally facing anchors rotatably carried by the distal end of the implant body, configured to embed into tissue in a vicinity of the annulus surrounding the heart valve, wherein the pairs of adjacent struts can be adjusted to change the angle and contract the implant body to the third configuration to reshape the annulus.
