A control mechanism for a catheter with a distal anchor. Suture threads extend from the anchor to the control mechanism. A first body contains a reel with a radial port through which the suture threads extend to be received in a termination structure on a second, partially concentric and axially coextensive body of the control mechanism. Rotation of the second body wraps and unwraps the sutures about the reel thereby to remove or introduce slack into the suture threads after the anchor device forms. Removing slack in the suture threads prevents complete straightening of the anchor device and therefore inadvertent removal of the catheter from the patient.
