Abstract
Apparatus, comprising: (i) a catheter (64); (ii) an implant (100), comprising a flexible longitudinal member (102), and a linking member (104) that extends from a first linking site (106a) of the longitudinal member to a second linking site (106b) of the longitudinal member, the implant having: (a) a delivery state in which the longitudinal member is coaxial with the catheter, and at least a portion of the linking member is disposed alongside the longitudinal member, and (b) an implanted state in which a first distance between the first linking site and the second linking site, measured along the longitudinal member, is greater than a second distance between the first linking site and the second linking site, measured along the linking member; and (iii) a plurality of tissue anchors (46), slidable through the catheter and with respect to the longitudinal member. Other embodiments are also described.

17. Apparatus for use with a heart of a subject, the apparatus comprising:
-
a catheter, transluminally advanceable to the heart; an implant, comprising; a flexible tubular member comprising a wall that defines a lumen, and a linking member that extends, outside of the tubular member, from a first linking site of the tubular member to a second linking site of the tubular member, the implant having; a delivery state in which (1) the implant is slidable through at least part of the catheter, (2) the flexible tubular member is coaxial with the catheter, and (3) at least a portion of the linking member is disposed alongside the tubular member, and an implanted state in which (1) a first distance between the first linking site and the second linking site, measured along the tubular member, is greater than a second distance between the first linking site and the second linking site, measured along the linking member, (2) the linking member has a mid-portion disposed outside of the tubular member between the first linking site and the second linking site, and (3) the mid-portion is not in contact with the wall of the tubular member for at least 0.5 cm of the linking member; a plurality of tissue anchors, slidable within the lumen; and at least one anchor driver, slidable within the catheter and within the lumen, and configured to drive the tissue anchors through the wall and into tissue of the heart. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
