In fabricating a header assembly of an implantable medical device, one end of a bore contact wire attached to a connector block is keyed with one guiding channel at an upper region of a feedthru adapter and through the adapter to its undersurface. An opposite end is bent into conformance with an orientation channel on the adaptor undersurface. A tip end of a feedthru wire connected to electronic circuitry of the medical device and projecting out of a casing mounting surface is bent for alignment with the orientation channel so end portions of the feedthru wire and bore contact wire are in end to end engagement, then welded together. A plastic header is molded to encapsulate the adapter, connector block, and bore contact wire and, when solidified, has an undersurface for engagement on the casing and an elongated receptacle aligned with a connector block bore to receive the lead.

Pre-molded header with universal tip-to-tip feedthru adaptor

An implantable medical device includes a sealed casing enclosing electronic circuitry and a plurality of electrical terminals connected to the electronic circuitry and projecting out of a mounting surface. A header has an undersurface for mounting engagement on the mounting surface of the casing and first and second oppositely directed elongated receptacles, the first receptacle being positioned proximate the electrical terminals. The header also includes at least one conductive connector block having a bore aligned with each of the first and second receptacles for receiving a proximal end portion of a lead extending through the elongated receptacle and carrying at least one electrical terminal and a wire electrically connects each of the connector blocks with an associated electrical terminal, at least the wire from the connector block associated with the first receptacle being of minimal length because of its close proximity to the plurality of electrical terminals.
