摘要：
Apparatus is provided that includes an implantable tissue anchor for delivery in a constrained state within a deployment tool. The implantable tissue anchor includes an anchor shaft and a tissue-coupling element, which extends from a distal end of the anchor shaft. The tissue-coupling element includes a wire and a tip, which is fixed to a distal end of the wire, and has, at a widest longitudinal site along the tip, a greatest tip outer cross-sectional area that equals at least 150% of an average wire cross-sectional area of the wire. The tissue-coupling element is shaped as an open shape that is generally orthogonal to the anchor shaft when the tissue anchor is unconstrained by the deployment tool. Other embodiments are also described.
