Abstract
Apparatus is provided, including a tissue-adjusting member configured to be coupled to tissue of a patient, a rotatable structure that is configured to adjust a tension of the tissue-adjusting member, a tissue anchor coupled to the tissue-adjusting member and configured to screw into the tissue of the patient, and a delivery tool reversibly coupleable to the rotatable structure. The delivery tool comprises a first actuating element configured to rotate the tissue anchor so as to facilitate screwing of the tissue anchor into the tissue of the patient while not facilitating rotation of the rotatable structure, and a second actuating element configured to rotate the rotatable structure while not facilitating rotation of the tissue anchor. Other applications are also described.
