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 defines a tapped region adjacent the second bore, and a smooth bore region which is longer than the length of the threaded portion of the setscrew to prevent the setscrew from being completely backed out of the tapped bore.
