Abstract
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.
