Patent ID: 7818070

Claim:
An implantable lead body, comprising: an internal core portion including an outer surface, a stylet lumen, a conductor lumen positioned near the outer surface of the internal core portion such that a web region is formed between the conductor lumen and the outer surface, and an axial slit formed through the web region to form a path between the conductor lumen and the outer surface of the internal core portion; a conductor extending within the conductor lumen of the internal core portion and including a distal terminal end; a contact extending around the outer surface of the internal core portion and including a contact slot; and a coupling including a first coupling region, a second coupling region and a third coupling region, the first and second coupling regions being contained within the conductor lumen of the internal core portion, the first coupling region being crimped around the conductor, and the distal terminal end of the conductor being contained within the first coupling region, the second coupling region extending distally from the distal terminal end of the crimped conductor and defining an isolation space, and the third coupling region extending radially outward from the isolation space, through the axial slit of the internal core portion; and a weld connecting the third coupling region of the coupling to the contact at the contact slot.
