Claim 12:
13. An apparatus comprising:
(a) a metal wire comprising:
(i) a proximal end defining a wire diameter, and
(ii) a distal end that includes a solderless spherical bead defining a spherical bead surface and a bead diameter that is greater than the wire diameter; and

(b) a conductor wire with a proximal end that is directly coupled with the proximal end of the metal wire at a joint, the joint being soldered or welded and
(c) an invasive probe that includes a distal end, the distal end of the invasive probe comprising:
(i) an electrically conductive dome with a wall comprising a circumferential portion and an end portion and defining a cavity therein;
(ii) an inner surface,
(iii) an outer surface,
(iv) at least one irrigation aperture at one location in the dome, and
(v) at least one assembly aperture at another location in the dome extending between the inner and outer surfaces, wherein the solderless spherical bead is positioned at least partially within the assembly aperture and fixedly sealed therein with adhesive in one of three positions of (i) the spherical bead surface protruding past the outer surface of the distal end of the invasive probe by a radius of the spherical bead; (ii) the spherical bead surface being flush with the outer surface, or (iii) the spherical bead surface being recessed from the outer surface by the radius of the spherical bead.
