Abstract

An anchor driver is provided that includes a driver head having a flexible ring. An anchor is provided that includes a coupling head, which is shaped so as to define: (a) one or more mating elements that engage mechanical coupling elements of the driver head such that rotation of the mechanical coupling elements rotates the mating elements, which in turn rotate the coupling head, and (b) an outer coupling surface, sized to be inserted into and engage the flexible ring. The anchor also includes a tissue coupling element fixed to the coupling head. The rotation of the mechanical coupling elements causes the tissue coupling element of the anchor to screw itself into tissue, thereby causing separation of: (a) the outer coupling surface of the coupling head from the flexible ring, and (b) the mating elements of the coupling head from the corresponding mechanical coupling elements. Other embodiments are also described.
