Claim:
1. A medical device lead comprising: an insulating tubular member having a proximal end, a distal end, and a lumen extending therebetween; an electrical conductor extending within the lumen from the proximal end toward the distal end; and a tubular conductive element disposed over the insulating tubular member and between the proximal end and the distal end, wherein the tubular conductive element is electrically coupled to the electrical conductor and has one or more kerfs formed in it to affect an electrical property of the tubular conductive element, wherein the one or more kerfs include kerfs formed in a helical pattern such that electrical current passing through the tubular conductive element travels along a helical path and the kerfs formed in the helical pattern have a variable pitch.
