1. A header assembly for connecting a conductor terminating at a body organ with control circuitry and at least one electrical energy storage device of an implantable medical device, the header assembly comprising:

  • (a) a first electrically conductive terminal having a first lead opening sized to receive a first portion of a lead for the conductor;

    (b) a second electrically conductive terminal having a second lead opening sized to receive a second portion of the lead for the conductor;

    (c) a body of polymeric material molded as a single piece to support the first and second terminals in a partially encased relationship so that the first and second terminals are prevented from moving by the polymeric material;

    (d) a first bore communicating from outside the polymeric body to the first and second lead openings aligned in a first co-axial relationship;

    (e) a first passageway extending into the body leading to the first terminal, and wherein a second passageway extends into the body in communication with the first terminal and the first passageway;

    (f) a third passageway extending into the body leading to the second terminal, and wherein a fourth passageway extends into the body in communication with the second terminal and the third passageway; and

    (g) wherein the first and third passageways are in communication with the second and fourth passageways and provide for receiving a feedthrough wire that is directly contactable to the respective first and second terminals.
