1. A medical lead, comprising:
- a lead body having an insulator and having at least one conductor, and wherein the insulator comprises, a first region formed by removal of at least a portion of the insulator, the first region exposing at least a portion of the at least one conductor, and a second region formed by removal of at least a portion of the insulator, the second region exposing at least a portion of the at least one conductor;
a first conductive pad positioned within the first region and electrically connected to the at least one conductor;
a second conductive pad positioned within the second region and electrically connected to the at least one conductor; and
at least one electrode welded to the first conductive pad and welded to the second conductive pad to electrically connect the at least one electrode to the at least one conductor through the first region and to the at least one conductor through the second region.
