A device and system for treating tissue includes an anchoring element at a distal end thereof for anchoring the device in a target portion of tissue and a coupling element with a magnet. The anchoring element and the coupling element are coupled to one another by a tether so that, when the anchor element is anchored in a target portion of tissue, the tether passes through the portion of tissue and the coupling element remains outside the portion of tissue. The closing device is configured to couple to a second closing device comprising a second anchoring element tethered to a second coupling element with a magnet to hold the target portion of tissue in a desired location relative to one another.
