Abstract
A header assembly for coupling a medical electrical lead to a medical stimulating device includes a header having a first bore for receiving a proximal terminal pin of the lead. A connector block coupled to the header has a second bore aligned with the first bore and a tapped bore transverse of, and in communication with, the second bore, and the assembly includes a setscrew with mounting threads of defined length threadedly engaged with the tapped bore. The tapped bore has first and second tapped regions spaced by a smooth bore region which is longer than the length of the threaded portion of the setscrew. As the setscrew is tightened, it has already been threaded through the first tapped region and resides within the smooth bore region, and then becomes threadedly engaged with the second tapped region such that the tip end becomes firmly engaged with the proximal terminal pin of the lead.
