Abstract
A joint assembly which may be used for affixing a helically wound lead conductor coil to an electrode of a pacemaker. The electrode has a longitudinal bore and a coaxial counterbore. One end of the coil is fittingly attached to a reduced diameter end of a press tube. The outer diameter of the extreme outer surface of the coil on the press tube is slightly greater than the inner diameter of the counterbore in the electrode. The reduced diameter end of the press tube with the coil thereon is fittingly inserted into the counterbore. This results in a solid connection between the lead conductor coil and the electrode without causing any visible alteration of the outer surface of the electrode.
