The connector is configured to connect the lead to an external control module. The helically coiled conductor has a proximal end mechanically and electrically connected to the connector. The conductor includes a plurality of filars mechanically and electrically connected to the connector. The first mechanical element includes a metal tube having a plurality of longitudinally spaced grooves formed along an exterior of the tube. The plurality of longitudinally spaced grooves receives at least some of the plurality of filars. The at least some of the plurality of filars electrically connected to the first mechanical element such that the first mechanical element is configured as an electrode to deliver electrical stimulation to portions or systems of a body from the external control module. ## Claims ### Claim 1 A temporary implantable medical device lead comprising: a connector configured to connect the lead to an external control module;
