1. A method of treating regurgitation in a patient's heart having a ventricle, an intraventricular septum and an atrioventricular valve, the method comprising:
providing an implantable assembly including an active anchor, a septal anchor and a tether having a working portion extending between the active anchor and the septal anchor and a proximal portion associated with the active anchor;
positioning the septal anchor adjacent the intraventricular septum;
locating the active anchor adjacent a wall of the ventricle, the active anchor including an abutment portion adapted to abut against the wall and a tether portion rotatably coupled to the abutment portion; and
engaging the tether portion of the active anchor with an adjustment tool and applying a rotational force to the tether portion such that a relative rotation of the portions adjusts a first length of the working portion and a second length of the proximal portion of the tether;
wherein decreasing the first length of the working portion increases a tension of the working portion of the tether so as to reshape the ventricle; and
wherein the locating step includes coupling the active anchor to a distal end of the adjustment tool and positioning the abutment portion of the active anchor adjacent the wall of the ventricle using a proximal portion of the adjustment tool.
