Tubular lead electrodes and methods

This document discusses, among other things, a lead assembly including an implantable lead body including a lumen, a conductor extending through the lumen in the lead body, and an electrode including a tube having an internal surface. In an example, at least a portion of the tube is formed into a helix. The conductor is electrically coupled to the internal surface of the first tube. An example method includes winding a tubular electrode around a mandrel, extending a conductor through a lumen in a lead body for a medical device lead assembly, and extending the conductor into the tubular electrode.
