Abstract: An implantable assembly adapted for reshaping a cardiac chamber of a heart in a patient is disclosed. The assembly is implanted by a tool having a tool proximal portion and a distal portion. The assembly includes an active anchor including an abutment portion adapted to abut against a wall of the chamber of the heart and a tether portion rotatably coupled to the abutment portion. Each of the abutment portion and the tether portion configured to independently couple with a tool. The assembly further includes an interventricular septal anchor for coupling to a septum of the heart and a tether having a working portion having a first length, extending between the active anchor and the septal anchor, and a tether proximal portion having a second length. The abutment portion is releasably locked to the tether portion and configured such that a preselected torque applied to the tether portion of the active anchor unlocks and causes a relative rotation of the tether portion with respect to the abutment portion.
