Patent attributes
An apparatus including an implant configured to be coupled to cardiac tissue of a patient, the implant including a sleeve; a spool coupled to the implant; a flexible contracting member coupled to the spool and the sleeve such that winding the contracting member around the spool tightens the contracting member; and a tissue anchor including a distal tissue coupling element configured to couple the tissue anchor to the cardiac tissue of the patient; and a proximal implant-receiving element configured to receive at least a portion of the implant and facilitate coupling of the implant to the tissue anchor; and a proximal implant-receiving element including an implant-restraining element coupled to a portion of the implant-receiving element, the implant-restraining element being configured to restrain the implant from separating from the implant-receiving element.
