Abstract
A tissue anchor system is provided that includes a first tissue anchor, a second tissue anchor that is separate and distinct from the first tissue anchor, and one or more tethers, which are configured to couple the first tissue anchor to the second tissue anchor. When the first tissue anchor is unconstrained, a head thereof is coaxial with an axis of a shaft thereof, and a tissue-coupling element thereof extends from a distal end of the shaft, is generally orthogonal to the axis, and is shaped such that if the tissue-coupling element were to be projected onto a plane that is perpendicular to the axis, at least 80% of an area of a projection of the tissue-coupling element on the plane would fall within a first angle of 180 degrees in the plane having a vertex at the axis. Other embodiments are also described.
