1. A method for improving cardiac function by reducing ventricular volume, comprising the steps of:

  • inserting by percutaneous approach a tether installation device into a patient; and

    inserting said tether installation device through the lateral wall of the left ventricle of the patient'"'"'s heart;

    attaching at least one tethered papillary muscle anchor from within said tether installation device to a papillary muscle within said left ventricle;

    withdrawing said tether installation device from said left ventricle such that the tether of the tethered papillary muscle anchor tranverses the left ventricular wall and extends from the inside to the outside of the left ventricle;

    attaching a pledget to the tether portion outside the left ventricle to form a wall anchor;

    wherein said papillary anchor and said wall anchor are joined by the tether to change the geometry and reduce the volume of the left ventricle.
