Incorporated into a pacemaker electrode, the adaptor essentially comprises an anchor element and an expander element insertable respectively into the spiral wound wires of a previously implanted electrode catheter, the ends of which are bared a suitable distance from their protective outer sleeve to facilitate the connection; the anchor element is inserted coaxially into and retained by the inner wire, while the expander element is hollow, coaxially encompassing the anchor element and affording a tapered profile that lodges stably between the outer wire and the insulating sheath of the inner wire. Use is made of a screw adjustment mechanism, associated with the end of the electrode farthest from the wires, to draw the electrode and the catheter together and seat the ends of the wires tightly in an encapsulating socket afforded by the electrode itself.
