ABSTRACT:
The invention is an implantable electrical stimulation lead for chronic or long term use that has an improved electrical connection between the electrode and conductor. This is accomplished through the use of metal coils embedded in the sidewall of the lead body. A wire conductor providing electrical continuity from a proximal electrode to a distal electrode has a protruding portion extending through the sidewall. This protruding portion can reside adjacent to either a proximal or a distal electrode. In any event, the protruding portion of the lire is captured underneath a ring electrode that is physically deformed into direct contact with the metal of the wire, preferably by swaging. This serve to make electrical conductivity between the wire and the electrode with the embedded coil serving as support during the swaging process.
