1. A method for use at a heart of a subject, the method comprising:
advancing a distal portion of a delivery tube into a chamber of the heart;
via the delivery tube, advancing an implant to the heart;
implanting the implant within the chamber such that:
a first portion of the implant is anchored to a first site on a wall of the chamber,
a second portion of the implant is anchored to a second site on the wall of the chamber, the implant having a mid-portion disposed longitudinally between the first portion and the second portion,
the mid-portion extends in a curved path along the wall of the chamber between the first site and the second site, and
an elongate contraction member of the implant cuts across the chamber between the first site and the second site; and
subsequently, reshaping the chamber by reducing a direct distance between the first site and the second site by tensioning the elongate contraction member such that a length of the elongate contraction member that cuts across the chamber between the first site and the second site becomes reduced.
