Abstract:
1. Apparatus, comprising: a tissue anchor having a central longitudinal axis; an adapter head coupled to a proximal portion of the tissue anchor, the adapter head being shaped so as to define an annular element; a connecting element coupled to the proximal portion of the tissue anchor via the adapter head, the connecting element being shaped so as to provide an annular loop surrounding a portion of the adapter head, the annular loop being centered around the central longitudinal axis, the annular loop defining an opening having a diameter that is smaller than an outer diameter of the annular element of the adapter head such that the annular loop is axially constrained between (1) the annular element of the adapter head and (2) a proximal end of the tissue anchor; and a flexible longitudinal member coupled to the connecting element, the annular loop of the connecting element facilitating rotation of the tissue anchor about the central longitudinal axis such that the tissue anchor can rotate about the central longitudinal axis with respect to the annular loop and the flexible longitudinal member.
