1. A method comprising:

  • causing a catheter to traverse a body lumen to place a delivery tool with a valve support attached to the delivery tool at an annulus of a heart valve, the valve support having a plurality of barbs or hooks attached thereto, and the delivery tool comprising a tapered outer surface having interconnected struts defining apertures;

    pushing the delivery tool distally through the annulus from one heart chamber to another heart chamber causing the delivery tool to radially dilate the annulus to a configuration determined by the delivery tool;

    while the annulus is dilated, attaching the hooks or barbs into tissue at locations along the annulus;

    after the support is attached into the tissue, moving a tip of the delivery tool proximally to rotate the barbs or hooks about the support to embed the barbs or hooks more securely into the tissue; and

    causing the valve support to contract to a smaller diameter.
