1. An apparatus for delivering a helical anchor to tissue of a valve annulus comprising:

  • a catheter having a first lumen and a second lumen, wherein a distal tip of the catheter has an angled surface, and a distal end of the first lumen is disposed distal of a distal end of the second lumen on the angled surface of the distal tip;

    a needle slidably disposed within the first lumen and extendable from the distal end of the first lumen, wherein the needle has a lumen that is configured to retain the helical anchor in a straightened state; and

    a clip disposed within the second lumen and having a distally-extended position in which the clip is distally extended from the distal end of the second lumen, wherein in the distally-extended position the clip is disposed radially adjacent to the distal end of the first lumen for anchoring the distal tip of the catheter to the valve annulus, whereby when the helical anchor is configured to be deployed from a distal end of the needle into tissue of the valve annulus, the helical anchor is configured to be disposed distal of the clip in the distally-extended position.
