1. Apparatus, for use at tissue of a heart of a subject, the apparatus comprising:
an anchor, shaped to define a tissue-penetrating helix;
a guidewire coupled to the anchor;
an implant:
transluminally advanceable along the guidewire toward the anchor, and
intracardially couplable to the anchor to become secured to the tissue by the anchor; and
a deployment tool, reversibly coupled to the anchor, comprising a lance, and configured to:
transluminally advance the implant and the anchor to the heart,
stabilize the anchor at the tissue by driving the lance into the tissue,
anchor the anchor to the tissue by driving the tissue-penetrating helix into the tissue while the anchor remains stabilized at the tissue by the lance in the tissue, and
subsequently, retract the lance from the tissue while leaving the implant secured to the tissue by the anchor anchored to the tissue.
