Claim 22:
23. A system, comprising:
a multi-component tubular system transluminally advanceable into a heart of a subject;
a first electrode configured to contact skin of the subject;
an implant configured to treat a native atrioventricular valve of a patient by changing a shape of an annulus of a valve of the heart, and comprising:
a sleeve having a lumen and at least a proximal end, the proximal end being shaped so as to define an opening,
a closure element coupled to the sleeve in a vicinity of at least one end, the closure element comprising a flap having (1) an open state and (2) a closed state in which the lumen is in reduced fluid communication with outside of the sleeve compared to when the flap is in the open state, and configured to be biased toward assuming the closed state,
a contraction wire, and
a tissue anchor comprising a coupling head and an electrically-conductive helical tissue-engaging element, wherein the tissue anchor is configured to act as a second electrode;

an anchor driver having a distal end that is reversibly couplable to the tissue anchor and configured to advance the tissue anchor through the multi-component tubular system and out of a distal end of the multi-component tubular system, and to anchor the distal helical tissue-engaging element to tissue inside the heart; and
a control unit electrically coupled to the first electrode and the tissue anchor, the control unit comprising circuitry configured, while the first electrode is in contact with the subject and the tissue anchor is located inside the heart of the subject, to receive an electrical signal from the first electrode and the tissue anchor, and provide information indicative of a location of the tissue anchor inside the heart based on the electrical signal.
