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.

Abstract
A tissue anchor includes an anchor member formed from a generally flexible material. An activation member, which may be a tensioning member, causes proximal and distal end portions of the anchor member to move toward each other into a shortened configuration suitable for anchoring against the tissue. The tissue anchor can optionally be deployed and activated using a catheter device.

19. A system for use with tissue of an annulus of a heart valve of a subject, the system 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, and operatively 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; and a catheter device configured to facilitate securing of the second end portion to the tissue, and to facilitate securing of the first end portion to the tissue subsequently to the securing of the second end portion to the tissue; 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, and the implant is configured to reshape the annulus of the heart valve.
