1. A method for use at a tricuspid valve of a heart of a subject, the tricuspid valve having an annulus and being disposed between a right atrium and a right ventricle of the heart, the heart having a coronary sinus, and the method comprising:
using a first delivery device:
transluminally advancing a first anchor to the coronary sinus, and
anchoring the first anchor inside the coronary sinus;
using a second delivery device:
transluminally advancing a second anchor to the right atrium, the second anchor including a proximal portion, a center portion, and a distal portion that is pivotally coupled to the center portion, and
anchoring the second anchor at a site that is across the annulus from the coronary sinus by:
while the distal portion is disposed adjacent and parallel to the center portion, driving the distal portion from the right atrium, through the annulus at the site, and into the right ventricle,
seating the distal portion against a ventricular surface of the annulus such that (i) the distal portion is disposed perpendicular to the center portion, (ii) the center portion extends through the annulus, and (iii) the proximal portion is disposed in the right atrium;
while the first anchor remains anchored inside the coronary sinus and the second anchor remains anchored to the site, reducing a distance between the first and second anchors by applying tension to a tensioning member coupled to (i) the proximal portion of the second anchor and (ii) the first anchor; and
maintaining the tension by locking a lock member to the tensioning member.
