1. An implant for reshaping a heart valve annulus, comprising:

  • a tubular body having a proximal end, a distal end, a central lumen and a longitudinal axis extending therethrough, the tubular body dimensioned for positioning within an atrium and attachment to tissue surrounding the heart valve;

    the tubular body comprising at least a first pair of adjacent struts joined at a proximally facing apex, and at least a second pair of adjacent struts joined at a distally facing apex;

    a plurality of distally facing anchors on the distal end of the tubular body, the anchors configured to embed into tissue surrounding the heart valve;

    a moveable restraint carried by the tubular body and configured to at least partially surround the first pair of adjacent struts, wherein the moveable restraint is axially movable relative to the proximally facing apex along the first pair of adjacent struts toward the distal end to decrease an angle between the first pair of adjacent struts; and

    a rotatable threaded member secured with the proximally facing apex, the rotatable threaded member extending through the moveable restraint, wherein rotation of the rotatable threaded member causes the moveable restraint to move axially along the first pair of adjacent struts.
