1. An apparatus for use with tissue of an annulus of a heart valve of a subject, the apparatus comprising an annuloplasty implant that comprises:

  • an elongate fabric member configured to be anchored to the tissue, and to move between an elongate configuration and a shortened configuration, the fabric member having a first end portion, a second end portion, and a compressible intermediate portion between the first end portion and the second end portion; and

    a tensioning member;

    having a first tensioning-member end and a second tensioning-member end,defining a first segment and a second segment by being turned back on itself at a turn such that (i) the first segment extends between the first tensioning-member end and the turn, (ii) the second segment extends between the turn and the second tensioning-member end, and (iii) the second segment is alongside the first segment, andoperatively connected to the fabric member by the first segment and the second segment being threaded, along the fabric member and alongside each other, between the first end portion and the second end portion, such that the fabric member can slide relative to the tensioning member,wherein;

    the turn of the tensioning member is disposed at the second end portion of the fabric member,the operative coupling of the tensioning member to the fabric member is such that tensioning of the tensioning member causes the fabric member to move from the elongate configuration to the shortened configuration by the tensioning member (i) pulling both the first end portion and the second end portion toward the intermediate portion, and (ii) compressing the intermediate portion, andthe implant is configured to reshape the annulus of the heart valve.
