Abstract
A lead body for use with medical devices and method for lead body manufacture are provided. The lead body defines a lumen. The lumen has an electrically conductive material deposited on the lumen wall. The lead body'"'"'s manufacture includes coating a lumen wall of a lead body with a conductive material to provide a conductor between the proximal and distal ends of the lead body. The manufacture further includes fitting sleeves electrically connected to electrical elements within the lumen to provide an electrical connection between the sleeve and the conductive material.
